For each only returns first iteration - php

Question

I'm trying to run through an object. I'm having an issue with my initial for each only running through the first iteration. So everything is great, but I'm only getting one iteration while their are 3. Any ideas why this may be happening?

exit(var_dump($rowsItemA));
$numItems = count($rowsItem);
$i = 0;
//exit(var_dump($rowsItem));
foreach ($rowsItemA as $rowsItem ){

Answer 1

This is because, you have made $port_item = "" in brginning of the loop.
foreach ($rowsItemA as $rowsItem ){
$port_item = "";// declaring as null here(remove this.)
So in every loop your value is reinitialized, and you are getting only 1 element(last element of your array)
