iterate through directory

[scorpion]

Does anybody know how to iterate through each file in a directory and changes the file permissions of each file in php? Also you only want to do this for files with a certain extension. (i.e. not your .php script of course)

You will need to obtain a directory handle using opendir [php.net]. Then calling readdir [php.net] will return all filenames in that directory. If you are done closedir [php.net] will close the directory handle.

$dir = '/path/to/files'; 
if ($handle = opendir [php.net]($dir)) { 
 while(false!== ($file = readdir [php.net]($handle))) { 
   if ($file == '.' && $file == '..') continue; 
   if(!is_file [php.net]($dir.$file) && preg_match [php.net]("'\.(html¦jpe?g¦gif)$'", $file)) continue; 
   chmod [php.net]($dir.$file, 0777); 
 } 
 closedir [php.net]($handle);  
}
