umask
(PHP 4, PHP 5)
umask — Changes the current umask
Description
int umask
([ int $mask
] )
Parameters
-
mask
-
The new umask.
Return Values
umask() without arguments simply returns the
current umask otherwise the old umask is returned.
Examples
Example #1 umask() example
<?php
$old = umask(0);
chmod("/path/some_dir/some_file.txt", 0755);
umask($old);
if ($old != umask()) {
die('An error occured while changing back the umask');
}
?>
Notes
Note:
Avoid using this function in multithreaded webservers. It is better to
change the file permissions with chmod() after
creating the file. Using umask() can lead to
unexpected behavior of concurrently running scripts and the webserver
itself because they all use the same umask.
