[PHP] Searching for a file.

[Vincent M.]

Hello,

I am looking for a way to search a file knowing the beginig of his name. 
For exemple, I know that the file I am looking for is:
montreal_000013_120.jpg
But I just know:
montreal_000013
And I can't know _120.jpg

So at this time I did this:
$dirthumbs = $dir."/thumbs" ;
$direc_src_obj2 = dir($dirthumbs) ;
while($entry=$direc_src_obj2->read()) {
  if( substr($entry, 0, 15) == "$begining"){
    $return[$i]["thumb"] = "$entry" ;
    break ;
  }
}
It works but it's not enough fast :-(
For resume, is there a way to do something like that:
ls montreal_000013*
without using the passthru function, I am looking for a native php 
function doing ls $mychar*

Thanks,
Vincent.
