How PHP executes the chmod command recursively on a folder

This article mainly introduces PHP to the folder recursive execution chmod command method, can implement recursive execution chmod command to change the function of folder execution permissions, the need for friends can refer to the following

The example in this paper describes how PHP executes the chmod command recursively on a folder. Share to everyone for your reference. The specific analysis is as follows:

Here, the folder and file recursively executes the chmod command to change the execution permissions

<?php function Recursivechmod ($path, $filePerm =0644, $dirPerm =0755) {//CHEC   K If the path exists if (!file_exists ($path)) {return (FALSE); }//See whether-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, $dirPerm);   }//When we do with the contents of the directory, we chmod the directory itself chmod ($path, $dirPerm);  }//Everything seemed to work out well, return true return (true); }?>
