Description:
------------

From manual page: http://www.php.net/function.glob
---
Documentation shortcoming for glob().

glob() does not seem to find any pattern that is longer than 50 characters.


In particular, if one expands the search pattern to remove case sensitivity using sql_regcase() or an equivalent function as available the glob() manual page, (eg. which transforms "cake*" into "[cC][aA][kK][eE]*"), the number of characters is reduced four times to about 12 characters.

This 50 character limitation should be documented in my opinion.


Test script:
---------------
//recursive glob() find 
function find($dir, $pattern){

 //get a list of all matching files in the current directory
 $files = glob("$dir/".$pattern);
	
 //find a list of all directories in the current directory
 //directories beginning with a dot are also included
     foreach (glob("$dir/{.[^.]*,*}", GLOB_BRACE|GLOB_ONLYDIR) as $sub_dir){
         $arr   = find($sub_dir, $pattern);  // resursive call
         $files = array_merge($files, $arr); // merge array with files from subdirectory
     }


    //return all found files
     return $files;
}



Expected result:
----------------
Nil.
Alternatively, users can use preg_find (http://www.pgregg.com/projects/php/preg_find/preg_find.phps) which does not have a 50 character limitation.
