Note Submitter: codatrix at yahoo dot com ---- The following underlisted function called "fcountext" is a function I wrote, for counting the number of file extensions within a given directory. Hope you find it satisfactory as there is no alternative solution via PHP's core filesystem's functions for counting the number of file extensions within a given directory. <?php /* * Author: ORUNTA C. N. * Email: codatrix@yahoo.com * * Name: fcountext() * Function: To count the number of file extensions within a given directory. * Argument(s): $dir, i.e. directory path - for e.g. 'htdocs/yahoo/' * Return-type: Integer */ function fcountext($dir) { //Authenticate - if directory? if(is_dir($dir)) { //Open and establish directory handle/pointer $dp = opendir($dir); //Create extensible array $afile = array(); //Set initializer array; $i = 0; //Read contents of directory into array $afile, thus: while($content = readdir($dp)) { //Concatenate filepath $filepath = $dir.$content; //Confirm any initial value within array... if(!count($afile)) { //Authenticate - if file? if(is_file($filepath)) { //Get extension using PHP's 'pathinfo' $pathinfo = pathinfo($filepath); //Store into the array $afile[$i] = $pathinfo['extension']; } } else { //Authenticate - if file? if(is_file($filepath)) { //Get extension using PHP's 'pathinfo' $pathinfo = pathinfo($filepath); //Count array into $len $len = count($afile); //Compare $pathinfo['extension'] with elements of array $afile for($i=0; $i<$len; $i++) { if($afile[$i] != $pathinfo['extension']) $stat = 'T'; else { $stat = 'F'; break; } } //If Status is true, then store into array if($stat == 'T') { $afile[$len] = $pathinfo['extension']; } } } } //Count total no. of different extensions. $extnum = count($afile); //Return no. of ext. return $extnum; //Close directory closedir($dp); } else { //Return no Value return 'Invalid Directory'; } } ?> The above function can be incorporated as you deem fit into a class situation to be accessed publicly.
