Warning: preg_match() expects...

Hello, the above is the error I am receiving, this is the function...

[code]
function audio_files($filelist)
{
  $clean_files = array();
  $extensions = array('\.mp3', '\.aiff', '\.wav', '\.mid'); //add audio extensions
  $read_extensions = '(' . implode('|', $extensions) . ')';

  if(preg_match("#$read_extensions$#", $filelist))
  {
      $clean_files[] = $filelist;
  }
  return $clean_files;
}
[/code]

Note, $filelist contains ftp_nlist(). Now, I'm guessing this could be a problem with my web host, so I'll go 'head and post that to.

If anyone could resolve the preg_match() error I am having, please do so...help is appreciated.

That says it all; change your code to loop through the array.

Ah.

Well, being slightly new to PHP, would I use a foreach loop to do so? 

[effigy]

Yes. Assuming $filelist will always be an array:

[code]foreach ($filelist as $file) {
  // Each iteration will have a new file in $file until the array runs out.
}[/code]
