How to convert JavaScript statement to PHP array

$var = '[["tom",10,17.5],["af",13,["x",10,"y",12,"z",11]]]';

How should I convert this string to a PHP 开发者_如何学Carray?

That looks like JSON. Use json_decode.

<?php

$json = "[["tom",10,17.5],["af",13,["x",10,"y",12,"z",11]]]";

$obj = json_decode($json);
print $obj->{'tom'}; 
?>
