templatetamer looks like an environment that I would be interested in using; however, what support resources are available for templatetamer? Is there a news server, bulletin board, or other help resource for people new to templatetamer?

If you are going to work with templates, you can take a look at
TemplateTamer, which has IDE geared for such development.

If you're willing to purchase a commercial product I'd highly recommend
Zend's IDE.  I've been working on a large PHP development project for a
little over a year now and switched to the Zend IDE about three months
ago and it has really increased my productivity.

Hello,

currently there is only Wiki, and mail support. However, to compensate, I
try my best not to affer only answers to strictly technical support
questions, but also to all various questions on how to do something with TT,
or how to approach some problem with it. Quite often I compile answer to
such question and put it afterwards on the wiki as an example, so I have
double benefit from it. In the future I may open a mailing list or something
similar.

Hope that helps, and if you have any questions please do not hesitate to
mail me.

Hello

If you don't mind running a JVM you can use PHPEclipse with the Eclipse 
Framework. Additionally to the php plugin there are a lot of other plugins 
out there that  can assist you.

Yeah .. vim is my god too. You can do so many things with so little
keystrokes. And it basically has the best syntax highlighting I've ever
seen. With some easy tricks you can even let it highlight your own
functions. I haven't doen so, but I know it's possible :P... Also, it exists
on most servers so you can work directly on the server. Without having to
mess with (Samba) filesharing. Another advantage is that it runs both on
Linux as well as on Windows.

But when I'm done editing a certain block, what do I do to make it fold back
in again?)

Hi all.  I'm trying to install PHPDocumentor (www.phpdoc.org) and I'm
getting an error when using the pear install feature.

I've got the necessary files stored in /home/phpDocumentor-1.2.2 but
when I run pear install /home/phpDocumentor-1.2.2/package.xml I get the
following error:

Invalid checksum : 44835 calculated, 0 expected

I've been looking around on google but I haven't been able to find much
of any use.

Can anyone give me an idea as to what's causing this and how to fix it?

Cheers and TIA,

Pablo

How could I count the elements of each dimension of an array?

I have this script, but it failed, thanks for any help

<?

$ojpp[3] = "4";
$ojpp[0][1] = "1";

The problem with the code above isn't with how you count the dimensions of
the array, but how you assign values to the second and third dimensions.

Ordinarily, the code $ojpp[0][1] = "1" will create an array at $ojpp[0] and
set it's second element to be "1". On the first line of your code, however
you have *already* assigned the string value "1" to $ojpp[0].

So when PHP sees the code $ojpp[0][1] = "1" it thinks you're trying to use
the 'curly braces' syntax for accessing single characters of a string. This
syntax is not widely known, but essentially means you can access characters
in a string like elements of an array, by using curly braces. For example,<?
echo $string{2}; ?> will print the third character in $string. For reasons
unknown to me, PHP will also let you use square brackets on a string to
perform the same action ... eg <? echo $string[2]; ?> although this
alternate syntax is being phased out. ( For more info see:
http://us2.php.net/manual/en/language.types.string.php ).

So essentially PHP intereperets $ojpp[0][1] = "1" as being an attempt to
assign "1" as the second character to the string already assigned to
$ojpp[0]. Which begs the question: why assign "1" to $ojpp in the first line
of your code when you seem to want to reaplce it with an array on lines 5 -
8?

This kind of coding bug is a by-product of a type-juggling, permissive
languge that doesn't require you to pre-declare variables. To fix your code,
change the first line of your code to read:

$ojpp[0] = array();

Hope that helps,

Al

You'll have to be more specific. What exactly do you want to do? Add values
of an array together? Their keys?

1) Enable FULL error reporting.
2) For debugging purposes, instead outputting the image directly, write it
to
disk first.

Assuming you're using the gd lib functions, then whatever function you're 
using to output the image has an option to write to disk. As always see 
manual for details.

On a quick glance, three things stand out:

1) You allow underscores in the website domain, but these are not valid
characters for domain names.
2) You allow dashes in the first pattern, but do not escape the dash
character.
3) You have not provided a quantifier to the top-level domain pattern:
[a-zA-Z], so it is only looking for one character fits the class [a-zA-Z].

Hope that helps,

I'd also add (depending on the situation):

4) allow for https:// and ftp:// and other schemes 5) allow for .htaccess password combinations (guest:[EMAIL PROTECTED]) 6) allow for a trailing slash (http://example.com/) 7) allow for directories and files [paths] (http://example.com/path/to/foo.something) 8) allow for query strings (everything after the ?) and anchors (#)

#7 & #8 may seem stupid, but not everyone's base url is a full domain -- sometimes people are burried a few levels deep in directories, and you will undoubtedly get people copying and pasting things like 'example.com/index.html?id=5#foo'

Now, the above is starting to look pretty complex huh?

Take a look at http://php.net/parse_url

It returns the URL as an array of manageable chunks (scheme, domain, path, query, fragment) which you can then perform small, focused checks and regexp's on to check the url conforms to what you want.

G'day all
I have been able to the the image to display, which is a gif image of a
rectange.
But the text doesn't get displayed on the image.

There are no error messages on the screen
The other messages entitled true type fonts is a thread I started as well,
but the image was not being displayed on the screen at all.
So now I have the image but no text on the image.

What could be causing this, and what should I have a look at?


Thanks
P.S: the code I use is below

<?php
  header("Content-type: image/gif");
  $im = imagecreate(400,30);
  $white = imagecolorallocate($im, 202,112,112);
  $black = imagecolorallocate($im, 255,255,255);
  // Replace path by your own font path
  imagettftext($im, 20, 0, 10, 20, $black, "arial", "Testing... Omega:
&amp;#937;");
  imagegif($im);
  imagedestroy($im);
?>

If you had read and followed the advice given in response to your earlier 
posts I'm sure you would've solved your problem by now.

Again:

1) Enable FULL error reporting by including these lines at the top of your 
code:

  error_reporting (E_ALL);
  ini_set('display_errors', 1);

2) Output the image to file. Remember to comment out the header() for the time 
being.

3) And someone else suggested that you may have specified the name of your 
font file incorrectly. In my experience you *have* to specify a path to your 
font file. So if the font file was in the same directory as your script then 
use './name_of_font_file'. So if you had followed the above steps (at the 
least step 1) you would have seen the following error:

  PHP Warning:  imagettftext(): Could not find/open font in ...

and would have clued you into what the problem was.

PHP Gurus,
        I have a web site that helps people sign up for workshops and
classes. The classes happen away from any computer or web access. What I
want to do is be able to collect data about payment and attendance and
be able to send it to the web site for inclusion into the MySQL
database.
        Of course, I could go low tech and just have people write things
down and then later type in results when they finally get web access.
        However, if possible, I would like to take advantage of the fact
that the teachers of these classes all carry Palm Pilots. If it were
possible, could they record data in some fashion that would allow them
to copy the data over to their PC when they hot synch, and then upload
it to a page where it would automatically be integrated into the site
database.
        I have only the faintest notions about how this could work, and
I suspect it may simply not be possible.
        But on the other hand, I was wondering if it may be possible to
make use of the simple text editor on the Palm, or perhaps the newer
Excel editors (which I have not yet tried), to create a file of flat
data which could then be uploaded and interpreted by PHP and then
entered into the DB. It seems to me that a simple text file would
probably be easy to upload and read by PHP, but then I'd have to do more
work to get the teachers to conform to layout standards and do more
error checking since the text file allows for a wide range of mistakes
to happen. The Excel file would make it easier for the teachers to see
where to enter data and have less mistakes, but then it might be more
difficult to get the data out of it, through PHP, and into the database.
        If anyone has any pointers or advice about how to best approach
this problem, please let me know.

        Make a custom sheet in Excel for the
 teachers. Excel can generate a comma delimited
 (CSV) file out of a sheet. The you can very
 easily import that file into your PHP program

I need to add extra quotation marks in to the following insert command for
mysql.

I need one that is part of the info right before the |$wrapper resend and
right after the
$outgoing,nobody
$query = "insert into majordomoaliases
(domain,listname,var,address1,address2)values
(/"$domname/",\"$listname\",\"a\",\"$listdomain-$listname:\",\" |$wrapper
resend -C $domaincf -l
$listname -h $listdomain $listdomain-$listname-$outgoing,nobody\")";

The whole line should look like this when it is printed out to the page it
will be written to from the database
"|/var/wrapper resend -C /var/domaincf -l list1 -h domain.com
domain.com-list1-outgoing,nobody"

I am totaly stuped on haw to add this extra quotation mark no mater what I
do I get mysql errors.

Just curious about something I came across.
I was looking at the $GLOBAL array, to see what my script was leaving behind.
$GLOBALS contains a reference to itself.
Even though its a reference, whats the sense with that??
Once its global, why should it have to call on itself?
Im currently running php 4.3.4 on FreeBSD 4.9

Thanks

A script to try out ->
<?php

header('content-type: text/plain');

var_dump(isset($GLOBALS['GLOBALS']['GLOBALS']));  // returns true

// Prints out the $GLOBALS array
// including one reference to itself
// then starts another but quits with *RECURSION*
var_dump($GLOBALS);

?>

It's global isn't it? SOunds like completeness.

Well .. it basically just "Contains a reference to every variable which is
currently available within the global scope of the script. The keys of this
array are the names of the global variables.". Since $GLOBALS itself is
global, that too is contained.

So: 

        
var_dump(isset($GLOBALS['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS
']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBAL
S']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBA
LS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOB
ALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLO
BALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GL
OBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['G
LOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['
GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'][
'GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']
['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'
]['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS
']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBAL
S']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBA
LS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOB
ALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLO
BALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GL
OBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['G
LOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['
GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'][
'GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']
['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'
]['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS
']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBAL
S']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBA
LS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOB
ALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLO
BALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GL
OBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['G
LOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['
GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'][
'GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']
['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS']['GLOBALS'
]));

Will still print out true. the displaying of *RECURSION* is to prevent, well
.. ehmm, recursively printing out the $GLOBALS array over and over again.
This is something new in PHP 4.0.4. Read the manual on page
http://nl3.php.net/manual/en/function.print-r.php:

        Note: Prior to PHP 4.0.4, print_r() will continue forever if given
an array or object that contains a direct or indirect reference to itself.
An example is print_r($GLOBALS) because $GLOBALS is itself a global variable
that contains a reference to itself.

How can I read through a file and find a string and then replace it with a
new string and then save the whole file.

Below is a peace of what I need to search through. I need to find the string
subscribe_policy = open and replace it with subscribe_policy = open+confirm.
Then save the whole file.

I have tried str_replace but it just wipes out the original file.

$file = "/var/lib/majordomo/domain.com/lists/listname.config";
$fp = fopen("$file", "w+");
$content = fread($fp, filesize($file));
$replace= "subscribe_policy =  open+confirm";

$content2 = str_replace($search_str,$replace, $content);
fwrite($fp,$content2);
fclose($fp);

# If defined, only addresses listed in these files (colon or space

# which_access, or who_access is set to 'list'. This is less useful

# subscriber which includes a authentication number which must be
# sent back in with another subscribe command.
subscribe_policy = open

# unsubscribe_policy   [enum] (closed) <majordomo> /open;closed;auto/
# One of three values: open, closed, auto.  Open allows people to

Have php...

1) Make a copy of the original:
if ( ! copy ( $old_file, $backup_file . ".bak" ) ) {
        // Uh-oh, there's an error
}
2) Read the original and open a temp file:
$file_contents = file ( $old_file );
if ( ! $fp = fopen ( $temp_file, "w+" ) ) {
        //  Oh my, can't open the file
}
3) Parse and write:
for ( $i = 0; $i < sizeof ( $file_contents ); $i++ ) {
        $write_this = preg_replace ( $pattern, $replacement, $file_contents[$i] );
        if ( ! fwrite ( $fp, $write_this ) ) {
                // Darn, can't write to the temp file
        }
}
4) Cleanup and copy temp file:
fclose ( $fp );
if ( ! copy ( $temp_file, $old_file ) ) {
        // Zoinks, there seems to be a problem
}
It's 5:00 am for me, and I'm typing all this from memory, so there may be bugs :) You can remove the temp file if you so desire if the above runs without error.

I use PHP 4.1.2 under Linux (Kernel 2.4.18).
On files bigger than 2GB the php-function 'file_exists'
exits with 'Warning: stat failed on ... (errno=75 - 
Value too large for defined data type') ...

How can I solve this problem?
Thanks for every help.

Hi,

I'm trying to get the pdflib work...

I use pdflib 4.0.3 downloaded from pdflib.de and php 4.3.4 on Debian Linux.

I wrote this test code:
hi matthias, if you want to use this lib it's good to be familiar with classes and objects in php. the manual can help you at this. now to your code.
<?php

dl("libpdf_php.so");

$pdf = pdf_new();
you just created a php-object $pdf.
for your further methods you must explicit declare them to your objects:
pdf_begin_page($pdf, 421, 595);
$pdf->pdf_begin_page($pdf, 421, 595);
... and so on.
