I have a folder, inside this folder, have many subfolders, but I would like to scan all the subfolders, and scan all the .m file… How can I do so??

Here is the file:

/MyFilePath/
           /myPath.m
           /myPath2.m
           /myPath3.m
          /MyClasses/

                    /my1.m
                    /my2.m

You’ll want to look to the PHP docs for details on this: http://php.net/manual/en/function.readdir.php

Here’s an example that should do what you you want. It will return an array of all .m files in the sub directories. You can then loop through each file and read the contents if that is what you are interested in.

<?php
function get_m_files($root = '.'){ 
  $files  = array(); 
  $directories  = array(); 
  $last_letter  = $root[strlen($root)-1]; 
  $root  = ($last_letter == '\\' || $last_letter == '/') ? $root : $root.DIRECTORY_SEPARATOR; 

  $directories[]  = $root; 

  while (sizeof($directories)) { 
    $dir  = array_pop($directories); 
    if ($handle = opendir($dir)) { 
      while (false !== ($file = readdir($handle))) { 
        if ($file == '.' || $file == '..') { 
          continue; 
        } 
        $file  = $dir.$file; 
        if (is_dir($file)) { 
          $directory_path = $file.DIRECTORY_SEPARATOR; 
          array_push($directories, $directory_path); 
        } elseif (is_file($file)) { 
          if (substr( $file, -strlen( ".m" ) ) == ".m") { 
              $files[]  = $file; 
          }               
        } 
      } 
      closedir($handle); 
    } 
  } 

  return $files; 
}
?>
