I dont understand what you mean

do you have a url like http://myurl.com/index.php?theimage=img02&theimage3=img03 ?

ok sorry if i was confusing it really wasnt my intention. ill try to explain myself better.

 

i have a php variable - $variable - in which i have a looot of text.

example:

 

$variable = 'hell yeah i have text and a image <img src="http://www.google.com/image.gif"/>. isnt that cool? and another image maybe <img src="http://www.yahoo.com/yahooimage.gif"/>'

 

and i want to "extract" the two urls of the images:

 

1 - http://www.google.com/image.gif

2 - http://www.yahoo.com/yahooimage.gif

 

PS: Notice that the number of images is not constant ... it maybe 1 or 10.

 

thanks for your help .

Here is the code that should work

 

<?php
$variable = "this is some text, avec url= http://www.google.com/image.gif and this http://www.yahoo.com/yahooimage.gif";
$words = substr_count($variable, " ");
$words = $words+1;
$word = explode(" ",$variable);
$num = 1;
for($i = 0;$i <= $words;$i++)
{
$var = trim($word[$i]);
if(eregi("^(http|https):\/\/.+(\.gif|\.jpg|\.jpeg|\.png)$",$var))
{
	echo "{$num}. {$var}<br />";
	$num++;
}
}
?>

 

This code counts the spaces then adds one for the amount of words. then is explodes the spaces and checks to make sure if the word matches the regex. $num is just so it will say 1. url 2.url etc

 

You can thank Sasa for the regex

 

Hope this works

try

<?php
$variable = "this is some text, avec url= http://www.google.com/image.gif and this http://www.yahoo.com/yahooimage.gif";
preg_match_all('/(http|https):\/\/[^ ]+(\.gif|\.jpg|\.jpeg|\.png)/',$variable, $out);
print_r($out[0]);
?>
