Description
array 
glob ( string pattern [, int flags] )
     The glob() function searches for all the pathnames
     matching pattern according to the rules used by
     the libc glob() function, which is similar to the rules used by common
     shells. No tilde expansion or parameter substitution is done.
    
     Returns an array containing the matched files/directories, an empty array
     if no file matched or FALSE on error.
    
    Valid flags:
    
       GLOB_MARK - Adds a slash to each item returned
      
       GLOB_NOSORT - Return files as they appear in the 
       directory (no sorting)
      
       GLOB_NOCHECK - Return the search pattern if no 
       files matching it were found
      
       GLOB_NOESCAPE - Backslashes do not quote 
       metacharacters
      
       GLOB_BRACE - Expands {a,b,c} to match 'a', 'b', 
       or 'c'
      
       GLOB_ONLYDIR - Return only directory entries 
       which match the pattern
      
Note: 
        Before PHP 4.3.3 GLOB_ONLYDIR was 
        not
        available on Windows and other systems not using the GNU
        C library.
       
       GLOB_ERR - Stop on read errors (like unreadable  
       directories), by default errors are ignored. Added in PHP 5.1.0.
      
    
     
Example 1. 
       Convenient way how glob() can replace
       opendir() and friends.
       <?php
foreach (glob("*.txt") as $filename) {
    echo "$filename size " . filesize($filename) . "\n";
}
?> |  
 The above example will output 
something similar to: funclist.txt size 44686
funcsummary.txt size 267625
quickref.txt size 137820  |  
  | 
    Note: This function will not work on 
remote files as the file to
be examined must be accessible via the servers filesystem.
Note: 
      This function isn't available on some systems (e.g. old Sun OS).

     readdir(),
     closedir(), and fnmatch().
