You can try put_env('SHELL=/bin/bash');
  http://php.net/put_env

or if you making sure a script is ran under the shell you can
always call your script like:

  /bin/bash scriptname


and of course you can make it so you don't have to worry about your
environment  the file executible and add this to the first line:
  #!/bin/bash

I don't get any error.  It will ask me for the HTML code to the page and
just not work.  So I'm assuming that instead of being processed by
Apache and a preprocessor that can send it to PHP it's being printed to
the screen.

        Hi,

    sscanf does what it says, that is
it reads parameters, which means it expects to find
a string like this "33996344" and converts it
into an integer; that's why you get the result you get.
    This code does the job, but it's ugly: :).

<?php
$db='33996344,33996351,"GB","GBR","UNITED KINGDOM"
50331648,83886079,"US","USA","UNITED STATES"
94585424,94585439,"SE","SWE","SWEDEN"';

$lines=explode("\n", $db);

echo "<pre>";
print_r($lines);


foreach ($lines as $line) {
 $args = explode(",", $line);
 $array = sprintf("%010d,%010d,%2s", $args[0], $args[1], $args[2]);
 $array = explode(",", $array);
 list ($start, $end, $country) = $array;
 print_r($array);
}

print_r(printf("%010d", "33996344"));
echo "</pre>";

?>
    It uses sprintf.

Cheers,
Catalin

Hello,

Thanks for your answer!

You say that sscanf is doing it's job, so the documentation isn't very
clear.
I think it says that the format is equal to sprintf. And sprintf has %010d
in format that says that a var is a number with at least 10 digits, filled
with 0's. So I think that sscanf should do the job!

        Hi,

    sscanf is meant to READ paramaters, which means
it "transforms" the input into the desired output, which in
your case it was an integer and an integer looses, of course
the initial zeros "if any".
    What you wanted was, more or less, to transform the
parameters, job for which sprintf is better suited, at least in
this case.

Cheers,
Catalin

--- Begin Message --- Hi,

I've had troubles with an application that randomly (until now) unsets the session variable $_SESSION['editor']. I've hunted through all my code and finally managed to rule out everything else than the following couple of lines.

It unsets the session variable $_SESSION['editor'], but leaving others, like $_SESSION['admin'] untouched. At the first debug, I get "Admin: Y Editor: Y" printed (which is the way I suppose things to be), but at the second debug I just get "Admin: Y Editor:".


I can't find the error though. Any input appreciated!

You more than likely have register globals ON, so by setting $editor to some value above, you are also changing the value of $_SESSION['editor'].

Yes! Settings at ISP was with globals on, but at my local server they were off. Which added quite a lot to my confusion.

How about changing from an assignment operator "=" to a comparison
operator "==".

How about changing from an assignment operator "=" to a comparison
operator "==".

No. I want to step through each and every one of the rows in the result set, and that's done that way.

This may be the source of your problems.  i386, PPC, etc. are
architectures:

i386: x386 or higher
i586: Pentium II or higher (or equivalent)
i686: Pentium III or higher (or equivalent)
i786: Pentium IV or higher (or equivalent)
PPC: Mac Power PC
sparc: Sun Sparc

And the list goes on and on.  You have yet to tell the list if you are
running any oddball configuration.  Do you have any RAID or SCSI
controllers?  What about anything else?

I have a Pentium 4, this is probably the reason it's messing up. I don't
have any RAID or SCSI controllers and I've unplugged all my USB devices.
I'll try finding these things in i786, thanks for the help!

Well you don't need an i786 and probably won't find one.  i786 means you
can use it if you have a PIV but not a PIII -- basically it takes
advantage of architecture specific things.  You could use an i586 or
i686 or i386 fine -- you just wouldn't get any hyperthreading (I'm not
even sure if this is supported by the Linux kernel)

hi, i'm working on a function that highlights search results. problem: a search input like "te est"; two terms that match one word ("test"). the mysql query matches entries like this but my function isn't able to highlight them the right way:

<?
function highlight($src_terms, $src_terms_int, $result) {
$i = 0;
while ($i < $src_terms_int) {
$result = preg_replace('/('.$src_terms[$i].')/si', '<b>'.$src_terms[$i].'</b>', $result);
$i++;
}
return $result;
}

$search = "te est"; // user input to search for
$src_terms = explode(" ", $search);
$src_terms_int = count($src_terms);

$result = "this is just a test"; // result from database

print highlight($src_terms, $src_terms_int, $result);
?>

output: this is just a <b>te</b>st
(after the first term is highlighted the second one can't be found anymore.)

someone has an idea how to work around this?

thanks for your effort!

I don't think that would change anything. A search for "te est" then highlights "test" into "t<b>est</b>" and "te" can't be found anymore.

thanks anyway!!

Why not just allow for bold tags in the search term? What I mean is, I think you can get the results you want by allowing any number of open or close bold tags between each letter of the search term.

<?php
function highlight($src_terms, $src_terms_int, $result) {
$i = 0;
while ($i < $src_terms_int) {
$termWithOptionalBold = preg_replace('/(.)/', '(<\/?b>) *\1',$src_terms[$i]);
$result = preg_replace('/(<\/?b>)*('.$termWithOptionalBold.')(<\/?b>) */si', '<b>\2</b>', $result);
$i++;
}
return $result;
}
?>

Well yes, the kind of programming you plan on doing makes a large

I am using PHP 5 on Windows. I have downloaded the lastest from snaps. When I
try to use the mysqli functions, I get the error message: 

undefined function mysqli_connect()

I assume this means that mysqli support is not compiled into the Windows
version of PHP 5. However, there doesn't seem to be an extension dll for
mysqli either in the extension directory. And no line for it in the php.ini
file. 

Does anyone know about mysqli for Windows? Is it going to be compiled into
PHP 5? Or an extension included? When might this happen? Or is there an
extension available somewhere that I can get? Or is mysqli support available
only if I compile the Windows version myself?

Thanks,

Could you please be a little more specific about where on the manual page you
found the answers to my questions. I don't seem to be smart enough to find
them myself. If I was, I wouldn't have had to post the questions to the list.

--- Begin Message --- I'm having difficulty with understanding how to manipulate dates. It seems that there's no date object manipulate so we just pass around a bunch of values which is kinda of annoying.

A few things I'm trying to do:

1) Turn "MM/DD/YY" into an array like that returned from getdate(). I don't want to explode it or split it, I want to get an array just as if I used getdate() when the current day was MM/DD/YY.

2) Have a date string representing the first of the month and manipulate it to be the last day of the previous month.


If I can figure out how I'm supposed to do those, then the rest I will understand.

It just dawned on me that the timestamp parameter for getdate() is exactly what does this. So forget this one :)

2) Have a date string representing the first of the month and manipulate it to be the last day of the previous month.

This, I'm still wondering about. This is the code I have:

$month = $date['mon'];
$year = $date['year'];

if ($month == 1) {
$lastofprevmonth = date('t', strtotime('12' . '/01/' . ($year-1) ));
$lastofprevmonth = date('m/d/y', strtotime('12' . '/' . $lastofprevmonth . '/' . ($year-1)));
} else {
$lastofprevmonth = date('t', strtotime(($month-1) . '/01/' . $year));
$lastofprevmonth = date('m/d/y', strtotime(($month-1) . '/' . $lastofprevmonth . '/' . $year));
}


This is a far cry from the simple trick in other languages where you just subtract one from the first of the current month and your date then reflects the last day of the previous month. Can that be done in PHP?

You can use mktime() for this. To get the last day of a given month, just give the parameters for the "zeroth" day of the next month. For example, to get the date for the end of $month:

$month = 4;
$year = 2003;
$endofmonth = date('m/d/y',mktime(12,0,0,$month+1,0,$year));

$endofmonth is now the last day of the April for 2003 in MM/DD/YY format.

Hello,
I wanna create an online game in php and mysql and I have a problem. I have this

to be increased by 1. How can i do that?

Hi,

You'll need to set up some sort of scheduled task (if you're on unix, your
best bet is probably cron) - this task should call a script that connects to
your database and updates the field. If you like, you can write the script
in PHP and use something like lynx or wget to access it.

Or, if you only want the number_attacks to increase for every 10 minutes
that someone's playing (so it's not increasing throughout the night)
you'll probably just want to hold the time the game started in a
variable (or DB whatever) and just check with each page refresh to see
if it's time to increase the value.

There's other ways to do it, but your question was kinda vague so I'm
not sure what method would work best for ya.

Another way you can do it if you don't have that much access to the machine
is to record the last time it was updated and when someone loads the page,
you take the amount of time between the last incriment and now(). 

You then find out how many sets of 10 minutes have passed and incriment it
that many times (if it's less than 10 minutes, you'll be incrimenting zero
times).

The only problem with this is that if 100 people load the script in a 10
minute period, only one will be updating the database - the other 99 are
wasted traffic on the DB.

But if you have no other options...

That should work

what do you get with this:

print_r($array);

Nothing.  But it I run:

}
the data is definitely there.

I should add that the function is within a class so it is like this:

class excel_com  {
    (all tested - it works well)
    function getData() {
        etc..
    return $theArray;
    }
}

and here is an example of the call:

  $xls = new excel_com($workbook, $wks);
  $xls->Range($range, $inclHeader);
  $header=$xls->header;
  $data = $xls->getData();
  $xls->close();
  unset($xls);

Well from what is there that should work...very strange
does print_r show an empty array or nothing?

is $theArray created in the getData() function or is part of the class and
needs return $this->theArray

I think the example in the PHP manual goes something like...

function getData () {
// blah, blah
return array ('value1', 'value2', ...);
}

Then you would call it with
list ($var1, $var2, ...) = getData();
