php - Using variable in $_POST

I have an HTML form collecting data in which I have a series of fields that repeat for 18 rows (eg name1, name2, names, etc). This data is then passed into a PHP script using POST that processes that data.
What I would like to be able to do is create a loop that increments a counter so that the name field can be regenerated the required number of times. For example, a loop that does:-

$x=1; 
$processName = 'name' . $x; 
$nameField=$_POST['$processName']; 
printf("%s<br>\n",$nameField);
$x++;

This repeats and outputs each of the name fields from the initial form. Can this be done?

Solution:

This should solve your problem.

foreach ($_POST as $param_key => $param_val) {
    echo "name" . $param_val . "<br />\n";
}
