Yeah this is a BIT of topic...
I have this code:
<?
header("Content-type: image/svg+xml");
print('<?xml version="1.0" encoding="iso-8859-1"?>');
?>
<?php $text="This page uses PHP and SVG"; ?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 20000303 Stylable//EN"
"http://www.w3.org/TR/2000/03/WD-SVG-20000303/DTD/svg-20000303-stylable.dtd";

<text x="50" y="70" style="text-anchor:left; fill:#cccccc; font-size:26;
font-weight:15; font-family:Tahoma, Verdana; font-style:regular"><?php echo
$text; ?></text>
</svg>
See for yourself at:
http://www.torkiljohnsen.com/xperiment/index.psvg
This produces an error message (which you can read at the same page).
Why is this?
I had an xml/svg "specialist" make this code and it works perfectly on his
server... Anyone got ANY clue as to why this is happening?
ehhh... does anyone know of any good XML/SVG mailing lists out there ? :S
Didn't know where else to ask.....

It is not an error. The server just returns the script contents in plain
text, so it is not executed as a PHP script. You need to configure your
server to either process this script as a PHP script (it could be as
simple as rename its extension to .php) or configure it to process all
files with extension .psvg as PHP scripts.

This seems to work:
<?
define("_CONSTANT","/path/");
$string = "Click <a href=\"index.php\">here</a> to return to the main page.";
echo insertpath($string);
function insertpath($string) {
return preg_replace("/(<a
href=\")(.*\">.*<\/a>)/i","$1"._CONSTANT."$2",$string);
}
?>
Preg_replace allows you to use backreferences and access them via variables
such as $1 and $2, etc. Earlier versions of PHP required you to use \\1,
\\2 instead (see the documentation for preg_replace for more info). Each
section of the regex that is in parenthesis can be accessed. In the above
example, the (<a href=\") section is reprinted in the replacement string by
using $1, so on a so forth. The ".*" in the regex basically means match
"any old junk" since the "." refers to any single character and the "*"
means match the previous character zero or more times.

Forgot to mention that the "i" at the end of the regex means to make the
match case-insensitive...

Hi
This should work:
<?
$year = date("Y");
$spring = mktime (0,0,0,3,21,$year);
$summer = mktime (0,0,0,6,21,$year);
$autumn = mktime (0,0,0,9,21,$year);
$winter = mktime (0,0,0,12,21,$year);
$now = mktime();
if($now < $spring || $now >= $winter):
echo "Winter";
elseif($now >= $autumn):
echo "Autumn";
elseif($now >= $summer):
echo "Summer";
else:
echo "Spring";
endif;
?>
BTW There may be a bug in mktime() (php4) if you use 08 or 09 in the
month part...on my system this happens
(linux/apache/php4.1)
<?
$autumn = mktime (0,0,0,09,21,2002);
echo "date = ".date("d/m/Y",$autumn)."<br>";
?>
This prints: date = 21/12/2001
Also prints the same date for a month of 08

Thanks for the code snippet.
I see that everybody defaults to a season. I was doing a && comparison
between two seasons, so that's why it messed up when it into the new year.
Thanks to Bogdan and Tom for the helpers. I can go debug my code. And make
it less complicated. ^_^;;;
(It's was a lot longer than what is here.)

Nothing noted in the error log. The lines I have tried using are the EXACT
ones stated in the install.txt file. I basically copied them from the
install doc and pasted it into the httpd.conf file.

Hey, thanks for your time. You are busy, so I'll be brief
A.) If I were to use it, for a gd or mysql library, not oftenly, certainly
not more than 100 requests per day, would it affect the server negatively?
B.) Is there a delay in using it as oppossed to compiling them during
installation (or recompile)
I ask as I am not familiar at all with this feature, but saw it in some code,
(For ming, actually, to make flash movies) and it worked well for me
So, if I use it, am I doing myself a disservice? Or not? Thanks, I have no
clue
Joel
Ps. In case one asks why I'd use such a method, I am picklehead, no
intelligent answer, can be provided, I am just curious as I wasn't really
aware of such an option earlier on. Thanks ;)

Folks running Apache/Win32 should read this:
http://www.securiteam.com/windowsntfocus/5ZP030U60U.html
If you run in CGI mode you likely have a line similar to the
following in your httpd.conf:
ScriptAlias /php/ "C:\php\"
Also, if you run SAPI mode (apache plugin mode) and used
to run CGI, make sure that that line is commented out.
Has someone else got an idea for a workaround, without having
to go into safe-mode? Would safe-mode be able to prevent this?

An array contains various values eg: list of fruits.
Now i want to retrieve only unique fruits from the

No, that was not it. It gave me different results - but still wrong.
I have, however, got a little closer by extending the loop to 0-11,
for ($i=0; $i<11; $i++), and changing the display, starting with: echo
$num_vals[1][0];;. I had alla numbers shifted one step to the right before
when counting zeroes as well.
But - still the same problem. It doesn´t count correctly - and i can´t
figure out why...

Hi
I am writing a piece of code that uses contstant names that are dynamic.
My first solution was to use the
constant() function from within PHP.
My problem now is that the code needs to be compatible with PHP 3.018 and
early versions of PHP 4.
Can anyone offer a better way of doing things?
My current code is
$expected_result = 0;
for ($i = 1; $i <= $this->total_num; $i ++) {
$information = constant('CONS_' . $i);
$information_2 = split("[,]", $information);
if ( in_array($expected_result, $information_2) ) {
$expected_result = $i;
break;
}
}
Thanks in advance for any suggestions.
Mark
