You can use .each in jQuery to iterate an array

  $.each(course_category , function(index, item) {
});

Actually i dont know about php.But you can iterate an array using the above code in jQuery

The correct way is to use JSON:

var list = <?php echo json_encode($_REQUEST['cities']); ?>;

I assume you currently have two problems:

  1. Your PHP array is not encoded in any way, that JavaScript understand. Just use json_encode() here.

  2. If you receive an object (and arrays are just objects for that matter), you can't just output them using alert(), if you really want to see the contents. Again, you may use JSON.stringify() to solve this.

 

$(function() {
 var course_category = "<?php echo json_encode( $_REQUEST['cities'] ); ?>";
 alert( JSON.stringify( course_category) );
});

If you want to use the array contents later on, refer to plain for loops or jQuery's each().

<?php
$output = '';
foreach($_REQUEST['cities'] as $city){
    $output .= "'$city',";
}
$output = rtrim(",", $output);
?>
var course_category = [<?php echo $output; ?>];
