Maybe its a two dimensional array.

And use intval($string) to convert string into int value.

Example:
[php]

<?php $string="123"; $integer=intval($string); echo $integer; ?>

[/php]

Also,
if this is the string “339,341,343,347”

Then use explode function
explode($string,$xplode); /*here $xplode=’,’ */

After using explode function, use pregmatchall with integer class to extract integers and then use intval after pregmatch all.

Note: There should be no other chrachter in intval function other then integers.
