[SOLVED] Clean User Input Using Foreach

[matlyn]

I am currently passing data from a form to a .php script for processing.  First item is to clean user input with statements like:

 

$cleanFname = trim($_POST[fname]);

$cleanFname = strip_tags($cleanFname);

$cleanLname = trim($_POST[lname]);

$cleanLname = strip_tags($cleanLname);

etc...

 

times however many variables are in the form.  A few varables are ok but for a form with many variables this could get to be a long list.

 

Can this process be done combining foreach() with the $_POST array so that I can cover all passed variables with just a couple of lines of code vs a long repetitive list?

 

Thanks

i would assume this would work

 

foreach($_POST as $key => $val){

$$key = trim($val);

}

 

instead of having "clean" prefix the var name, they will just be named whatever they are in the post
