Question

I have a php array of objects istantiated from the following class:

class my_class {
    public $id;
    public $timestamp;
}

These are stored in an array with indexes 0,1,2…..

I am getting this array with jquery through the Session variable and I attempt to print it in the following ways:

var myclass_map = "<?php $_SESSION['myclass_map']?>";
$.each(myclass_map, function(key, value) {
    console.log(key + ' ' + value["id"]);
});

and

var track_map = "<?php $_SESSION['myclass_map']?>";
$.each(myclass_map, function(key, value) {
    console.log(key + ' ' + value.id);
});

but both give me an undefined reference to value while the print out the key. How can I access the objects variables?

At the very begining of your JS script, print the array converted to js format, using json_encode.

var track_map = <?=json_encode($map)?>;
