$_POST and array

[meshhat]

I'm passing 100 variables (named gaintxt0, gaintxt1....gaintxt100) using a POST. I would like to put these variables into an array. However, I'm having trouble with the syntax for the $_POST.

I'm trying to do something like this, but it's not working:

PHP Code:

<?
$myArray = array();

for($i=0; $i<=100; $i++){
   array_push($myArray, $_POST[gaintxt[$i]]);
}

?>

Any ideas?

PHP Code:

<?
$myArray = array();

for($i=0; $i<=100; $i++){
   array_push($myArray, $_POST['gaintxt' . $i]);
}

?>
