PHP Two Dimensional Array Convert to Comma Separated String

Now we will take the example of a two-dimensional array. In this example, we will convert two-dimensional array to comma separate string.

<?php
     // Two Dimensional array
	$array = array (
	  array ('01','03','02','15'),
	  array ('05','04','06','10'),
	  array ('07','09','08','11'),

	foreach ($array as $sub) {
	  $tmpArr[] = implode(',', $sub);
	}
	$result = implode(',', $tmpArr);

	echo $result;
