Question

How to grab all variables in a post (PHP)?
I don’t want to deal with $_POST['var1']; $_POST['var2']; $_POST['var3']; ...
I want to echo all of them in one shot.

If you really just want to print them, you could do something like:

print_r($_POST);

Alternatively, you could interact with them individually doing something like:

foreach ($_POST as $key => $value) {
    //do something
    echo $key . ' has the value of ' . $value;
}

but whatever you do.. please filter the input. SQL Injection gives everyone sleepless nights.
