[Resolved] making function to return 2 values? how?

[Fking]

i have the following function

unction pic_array($nav_file){
  global $image_extension, $thumbs_prefix, $create_thumbs
 if ( $dh = opendir($nav_file) )
  {
    while ( false !== ( $file = readdir($dh) ) )
    { if (strpos($file, "$image_extension") && (strpos($file, "$thumbs_prefix"))===false ) {$catch[]=$file;}
          elseif(!$create_thumbs && strpos($file, "$image_extension") && !(strpos($file, "$thumbs_prefix")===false)) {$catch_thumbs[]=$file;} }

  }
    rewinddir($dh);
    closedir($dh);
    if(!empty($catch)) {natcasesort($catch);
    $catch=array_values($catch);}
    if(!empty($catch_thumbs)) {natcasesort($catch_thumbs);
    $catch_thumbs=array_values($catch_thumbs);}


}

is it possible to use return for the two arrays created there, $catch[] and $catch_thumbs[]

making them global isn't acceptable at the moment but i'm thinking about it

[AstroTeg]

You could put those two arrays in a new array and return the new array. Maybe set array[0] = $catch and array[1] = $catch_thumbs.

Another option might be to use pass by value.

I'd definitely stay away from using globals here.
