次の文字列をシリアル化解除しようとしています:

次の js コードを使用します。

// % note: We feel the main purpose of this function should be to ease the transport of data between php & js
// % note: Aiming for PHP-compatibility, we have to translate objects to arrays
// * example 1: unserialize('a:3:{i:0;s:5:"Kevin";i:1;s:3:"van";i:2;s:9:"Zonneveld";}');
// * returns 1: ['Kevin', 'van', 'Zonneveld']
// * example 2: unserialize('a:3:{s:9:"firstName";s:5:"Kevin";s:7:"midName";s:3:"van";s:7:"surName";s:9:"Zonneveld";}');
// * returns 2: {firstName: 'Kevin', midName: 'van', surName: 'Zonneveld'}

しかし、これを行うと値を取り戻すことができません:
function testPHP() {
var ret;
ret = unserialize('a:1:{i:0;a:9:{s:12:"model_number";s:8:"TTN037-7";s:5:"price";s:4:"2935";s:10:"unit_price";d:2405.32000000000016370904631912708282470703125;s:8:"id_price";d:2935;s:9:"sales_tax";d:223.68000000000000682121026329696178436279296875;s:5:"sales";d:2380.32000000000016370904631912708282470703125;s:7:"service";s:2:"25";s:7:"freight";s:3:"306";s:13:"comm_category";s:3:"X24";}}');

私は何が欠けているでしょうか？
