PHP chgrp() Function


Hello dear readers! welcome back to another edition of our tutorial on PHP. In this tutorial guide, we are going to be discussing 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 function attempts to change the file group of the file: filename to the group. Only a 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
