PHP对文件夹递归执行chmod命令的方法

本文实例讲述了PHP对文件夹递归执行chmod命令的方法。分享给大家供大家参考。具体分析如下：

这里对文件夹和文件递归执行chmod命令来改变执行权限

    <?php
      function recursiveChmod($path, $filePerm=0644, $dirPerm=0755)
      {
       // Check if the path exists
       if(!file_exists($path))
       {
         return(FALSE);
       }
       // See whether this is a file
       if(is_file($path))
       {
         // Chmod the file with our given filepermissions
         chmod($path, $filePerm);
       // If this is a directory...
       } elseif(is_dir($path)) {
         // Then get an array of the contents
         $foldersAndFiles = scandir($path);
         // Remove "." and ".." from the list
         $entries = array_slice($foldersAndFiles, 2);
         // Parse every result...
         foreach($entries as $entry)
         {
          // And call this function again recursively, with the same permissions
          recursiveChmod($path."/".$entry, $filePerm, $dirPerm);
         }
         // When we are done with the contents of the directory, we chmod the directory itself
         chmod($path, $dirPerm);
       }
       // Everything seemed to work out well, return TRUE
       return(TRUE);
      }
    ?>
