[PHP] preg_match_all : not all regular expressions ?

[Jean-Jacques Méric]

[newbie, please help]

I'm trying to extract all URLs mentionning sound files from blocks of texts.

I first tried with ereg and the following code works fine :

$texte='TEST FIND<br>\net voici un fichier son 
http://serveur/repertoire/fichier.gig  ou 
ftp://serveur/repertoire/fichier.snd et 
ftp://serveur/repertoire/fichier.mp3 la suite 
http://serveur/repertoire/fichier.wav de mon texte';

if (ereg("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]\.(mp3|snd|wav)", 
$texte, $regs)) {
       echo $regs[0]."<br>\n";
   }
   else
   {
       echo "pas trouv&eacute;<br>\n";
   }

the only problem is that it will only extract the first URL, so I did a 
small modification to use preg_match_all  :

if 
(preg_match_all("[[:alpha:]]+://[^<>[:space:]]+[[:alnum:]/]\.(mp3|snd|wav)", 
$texte, $matches)) {

       for ( $i=0 ; $i < count($matches[0]) ; $i++ ) {
           echo $matches[0][$i]."<br>\n" ;
       }
} else {
          echo "pas trouv&eacute;<br>\n";
}
but I have the following error message :  *Warning*: Unknown modifier 
'+' in *e:\program files\easyphp1-7\www\test_ereg.php3* on line *4*

where line 4 is the line with the regular expression after preg_match_all

What's that ?
