// 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: serialize(['Kevin', 'van', 'Zonneveld']);
// returns 1: 'a:3:{i:0;s:5:"Kevin";i:1;s:3:"van";i:2;s:9:"Zonneveld";}'
// example 2: serialize({firstName: 'Kevin', midName: 'van', surName: 'Zonneveld'});
// returns 2: 'a:3:{s:9:"firstName";s:5:"Kevin";s:7:"midName";s:3:"van";s:7:"surName";s:9:"Zonneveld";}'
