Can I make "touch" create executable files by manipulating umask?
I'm getting to grips with this concept of the umask.
What I thought was, setting umask uga+rwx would result in creating files with all permissions for everyone. Seems not to be the case though. Read and write bits get set, but not the execute bit.
Is there some gap in my understanding, or is some other setting overwriting the usual behavior of umask?

umask
UMASK(3) 1 UMASK(3)umask - Changes the current umaskSYNOPSIS
int umask ([int $mask])
DESCRIPTION umask(3) sets PHP's umask to $mask & 0777 and returns the old umask. When PHP is being used as a server module, the umask is restored when
each request is finished.
PARAMETERS
o $mask
- The new umask.
RETURN VALUES umask(3) without arguments simply returns the current umask otherwise the old umask is returned.
EXAMPLES
Example #1
umask(3) example
<?php
$old = umask(0);
chmod("/path/some_dir/some_file.txt", 0755);
umask($old);
// Checking
if ($old != umask()) {
die('An error occurred while changing back the umask');
}
?>
NOTES
Note
Avoid using this function in multithreaded webservers. It is better to change the file permissions with chmod(3) after creating the
file. Using umask(3) can lead to unexpected behavior of concurrently running scripts and the webserver itself because they all use
the same umask.
