Hi Achilles - try something like this (you will have to read the exact
syntax in the manual cause its quite involved but ovious if you're logical
about it) :
<?php
$im = ImageCreateFromJPEG("$imagepath/$imagename")
// Create a gd image ($im) first.
$imtext=ImageCreate (100,22); // Make new, blank image 100x22px for text
$black = ImageColorAllocate ($imtext, 100, 100, 100); // Set black point
(some level of grey)
$white = ImageColorAllocate ($imtext, 255, 255, 255); // Set white point
$coords=ImageTTFText
($imtext,10,0,4,16,$white,$fontpath."arial.ttf","© Copyrightmessage
here 2003");
// Make TTF text and overlay it onto the image.
// Adjust $fontpath to your actual fonts directory.
ImageCopyMergeGray ($im, $imtext, 0, $newheight-22, 0,0,$newwidth,22,33);
// Centre text within image : Vary left & top parameters as required.
header("Content-type: image/jpeg");
ImageJPEG($im);
?>
Hope that helps (it works for me :-)
Cheers, Neil Smith.

Uhm, reffering to my post yesterday about IE try to open my PHP document as an XML
docuemnt I think I have located the problem.
If I don't make the PHP document XHTML compliant, then the PHP document loads into IE
ok. If I make the PHP document XHTML compliant, and build up a query string using the
dot syntax to identify tables and their columns and store this in a variable, I have
the errors.
Is this a known error, or has anyone experienced this before??
Cheers

Hi All-
I have searched for a while and cannot seem to find a quality error trapping
script!!!
Here is the situation, about a week ago one of the sites I built (which is
hosted on a shared server @ an ISP) went down. It went down because the
database server got moved. If I had been notified of the page errors that
were being generated, I would have been able to address the problem more
quickly and get their site back online. Luckily I found the problem, not the
client, however they did have a few people call and ask about it.
I was very angry and spent the rest of the day looking for a good error
trapping script, but I couldn't find anything. I am not very experienced
with error trapping in PHP, so here are a couple questions.
Aside from major code errors which should be fixed in development, things
like database connections won't stop the page from processing, so I am
wondering if PHP Errors (Warnings?) are stored in an array? Maybe I can put
a script into the php.ini appending every page with a small piece of code
that checks if any errors are present and if they are immediately email me.
Does that sound like a solid process for doing some basic alerting when PHP
scripts are generating errors?
I'd love to hear other people's input on this and how they are attacking
this problem!
Thanks!

My solution to the problem was to create an error reporting function. If
something goes wrong during key parts of the code (eg database erorr, mail
sending error, file reading error etc) then the error function is called. My
error reporting function attempts to send me an email, and if the email is
not sent instructs the user to send it manually. It also displays the normal
site interface without any php features (its hard coded in HTML - that way I
know it will ALWAYS work).
for example
MySQL_query( "Do Stuff to MySQL" )
OR error_report( '1', 'A MySQL Error occured while doing XYZ', __FILE__,
__LINE__, MySQL_error() );
I suggest you come up with a similar solution.

Paul,
you have to make sure, that the file you are trying to delete via unlink is
not currently in use by you application:
Example which WILL NOT WORK
$array = File("filename");
Unlink ("filename");
Another one NOT WORKING
$fh = fopen("filename");
$data = fgets($fh);
unlink("filename"");
But this one should work
$fh = fopen("filename");
$data = fgets($fh);
fclose($fh);
unlink("filename");
Regards
Norbert

Hello,
I am having problems getting the PDF extension to work with PHP on Windows.
I am running PHP 4.2.3 on Windows NT 4.0 using IIS as my internet server. I
have enabled the PDF extension in the php.ini file, with no apparent
success. When I try to load the page, I get an empty screen (i.e., no error
messages or undefined functions). It was my understanding that the Windows
module version of PHP had PDFLib libraries already built in. What might be
my problem?
Thanks, Bill

You need to make sure that IUSR has permissions on that file. When you call
from command line it's using your credentials. When it's from a browser,
it's IUSR_MACHINE

I have been having a huge problem with session IDs for a while now and
havn't been able to find a solution.
a simple code like this:
session_start();
echo session_id();
session_unset();
session_destroy();
run on a single php page will always give me the same id no matter how many
times I refresh the window. Now my understanding of sessions may be wrong,
but I though when you kill a session the id is killed as well. that would
mean when I refresh the page, a new id should be generated. Unfortunately
this does not happen and I can't figure out why. Only after I shut all
browser windows down, I get a new id and then the same story again.
Now, I know that the damn session is erased from the temp folder because I
see it happen, however the id sticks to the browser for whatever reason.
I am running php4.2.3 on w2k pro and IIS
can anybody help me please?
thanx,
iggy

PHP will use the session id that your browser specifies. If you have
php setup to store session id in cookies, every time you refresh the
page your browser is telling php what session id to use. Then when you
close your browser, your cookies may be getting deleted.

I want to display information from my database in two columns. I run
into a problem when there are three records. Another table data cell is
produced containing template material. Does anyone know a quick
solution to this problem? Code below:
$cols = 2;
$cell_count = 0;
if($numrows < $cols){
$cells = $numrows;
}
else{
$cells = $cols;
}
$test = $numrows/$cols;
if($test <= 0){
$rows = 1;
}
else{
$rows = round($test);
}
for($i = 0; $i < $rows; $i++){
echo"<tr>";
for($j = 0; $j < $cells; $j++){
$r=$lower_news->fobject();
$l_news_id = $r->id;
$l_news_title = $r->title;
$l_news_date = $r->date;
$l_news_username = $r->username;
$l_news_image = $r->image;
$l_news_intro = $r->intro;
$l_news_views = $r->views;
echo"<td width=\"50%\" align=\"left\">\n";
echo"<table cellpadding=\"0\" cellspacing=\"0\">\n";
echo"<tr>\n";

Try setting this variable as a session.
Here is a piece of code used once a user has been validated against a MySQL
dbase. ($uname was assigned from the login.html page)
<?
session_start();
$_SESSION['valid_user'] = $uname;
?>
Then, on each page that requires a preson to be logged in to access, this
goes at the top:
<?
//start the session
session_start();
//see if this person is 'valid_user', if not, redirect to LOGIN.HTML
if (!isset($_SESSION['valid_user'])){
header( "Location: login.html" );
}
//if he is 'valid_user' then load the page as normal
else {
?>
NORMAL PAGE CODE HERE
//allows me to assign a the info from 'valid_user' to a variable
$uname=($_SESSION['valid_user']);
<?
//end ELSE statement
}
?>
