File Directory Php


            // filefind accepts two parameters: 
// $basedirectory : The root of the directory tree to search 
// $needle : The file to find 
// 
// Return Value: 
// The fully qualified file name of the target file if it is found, 
// if the target file cannot be found then an empty string is returned. 
// 
// Sample Usage: 
// $fullpath = filefind($DOCUMENT_ROOT, "scriptEngine.php"); 
// if ($fullpath != "") 
// { Some processing (presumably involving scriptEngine.php) } 
// 
// NOTE: The search is case sensitive (because UNIX is) 
// This construct is to prevent the same include file from being included more than once, 
// lest it bloat the code.
