chgrp

CHGRP(3)								 1								  CHGRP(3)

chgrp - Changes file group

SYNOPSIS

       bool chgrp (string  $filename, mixed  $group)

DESCRIPTION

	Attempts to change the group of the file $filename to $group.

	Only  the superuser may change the group of a file arbitrarily; other users may change the group of a file to any group of which that user
       is a member.

PARAMETERS

	      o $filename
		- Path to the file.

	      o $group
		- A group name or number.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Changing a file's group

	      <?php
	      $filename = 'shared_file.txt';
	      $format = "%s's Group ID @ %s: %d
";
	      printf($format, $filename, date('r'), filegroup($filename));
	      chgrp($filename, 8);
	      clearstatcache(); // do not cache filegroup() results
	      printf($format, $filename, date('r'), filegroup($filename));
	      ?>

NOTES

       Note

	      This function will not work on remote files as the file to be examined must be accessible via the server's filesystem.

       Note

	      When safe mode is enabled, PHP checks whether the files or directories being operated upon have the same UID (owner) as  the  script
	      that is being executed.

SEE ALSO

       chown(3), chmod(3).
