Issuing a TOUCH command in PHP

[Anon]

I am in hopes that one of you PHP ghurus out there might take pity on this poor soul and help me come up with, what seems to be, a very simple PHP document.

I need to pass three variables via a form submission to the PHP document...

The first variable will be the file to be touched. The second variable will be the directory that the file is in. And the last variable is passed because when the PHP document is done, this variable must be passed back.

All it needs to do is grab these three passed variables, go to the directory, execute the command ...

touch -m {filename}

And then redirect them back to a URL that will be exactly the same every time, passing that last variable as a search string.

My thanks to any who are willing to help.

you kinda answered your own question:

$touch_file = $dir_var . $file;

touch($touch_file);
