Question

I have two arrays

<?php
 $x=array('store1'=>'A','store2'=>'B' ,...);
?>

and

<script type='text/javascript'>
  var x={"srote1": [12,13],"store2":[20,23] ....};
</script>

what is the optimal way to find the corresponding entries between these data structures

Answer 1

<?php
 $x=array('store1'=>'A','store2'=>'B' ,...);
?>

<script type='text/javascript'>
  var x=new Array("store1","store4","store10"); 
  var phpArrayX = <?=json_encode($x)?>;
</script>

-> now you can compare these two arrays in javascript (if that’s what you need)
