php foreach and positions

Question

php

$new_position = $_POST['new_position'];
$new_positionpieces = explode(",", $new_position);
foreach ($new_positionpieces as $value) {
    echo $value."<br>";
}

cat_37<br>cat_36<br>

From what I gather if I were to echo $new_positionpieces[0] it would say cat_37

How would I be able to get that 0 into a variable inside my foreach so that If it were something like

echo $item.' - '.$value.'<br>'; and outputs 0 - cat_37 so that I am able to put it into my db

Just remember if you are going to use the $key or $value for an insert query or printing to the screen make sure you escape them. – Oliver Bayes-Shelton Oct 02 '13 at 15:18
@OliverBS, that's good general advice, but the question doesn't mention how he's going to use the keys and values. – Bill Karwin Oct 02 '13 at 16:21
Yeah true, just noticed he edited the question and mentioned he was putting it in a DB :) – Oliver Bayes-Shelton Oct 02 '13 at 18:45

Oh yes I see. Then yeah, it's important to do that in a safe manner (http://stackoverflow.com/questions/60174/how-can-i-prevent-sql-injection-in-php). – Bill Karwin Oct 02 '13 at 18:49
