PHP chgrp() Function


Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP chgrp() Function.

The built-in PHP chgrp() function can be used to change file group.

Syntax

Following below is the syntax to use this function -

bool chgrp ( string filename, mixed group )


This PHP function attempts to change the file group of the file: filename to the group. Only the superuser may change group of a file arbitrarily, other users may change the group of a file to any group of which that user is a member.

Return Value

This built-in PHP function returns TRUE on success and FALSE on failure.

Example

Try out the below example -

<?php
   $filename = "/PhpProject/sample.txt";
   $format = "%s's Group ID @ %s: %d\n";
   printf($format, $filename, date('r'), filegroup($filename));
   chgrp($filename, "admin");
   clearstatcache();  // do not cache filegroup() results
   printf($format, $filename, date('r'), filegroup($filename));
?>

Output

When the above code is executed, it will produce the following result -

/PhpProject/sample.txt's Group ID @ Fri, 22 May 2020 07:42:21 +0200: 0
/PhpProject/sample.txt's Group ID @ Fri, 22 May 2020 07:42:21 +0200: 0
