PHP: Get File Names From A Specified Directory

Get file information from a given directory. Here the following example code to list the .php files in the particular folder.

Code:

$dir = $_SERVER['DOCUMENT_ROOT'].'/OpenInviter/';
$dh = opendir($dir);
while (($file = readdir($dh)) !== false) { 
  if (eregi("\.php",$file)) 
   { # Look at only files with a .php extension
      $string .= "$file";
    $string .= "<br>";
      $fileCount++;
   }
}

if ($fileCount > 0) {
  echo sprintf("<strong>List of Files in <br> %s</strong>
%s<strong>Total Files: %s</strong>",$filePath,$string,$fileCount);
}

Output:

autoupdate.php
config.php
