php ajax multiple data requests - php

Question

I have problem with getting multiple data with ajax.
I have cart and if I add (+) more quantity then it crashes, with one data parameter it works correctly, but if I try multiple it gives wierd big number.
If im not using VAT + Total cost then it works, but if I use VAT + total I get multiple dot numbers..
Example: 251.52254.5141.92 // without VAT and Total cost price is 251,52 (251.52 254.51 41.92)
Example2: 262264.9943.6666666667 // added one qty more..

Try this:
$.ajax({
url: 'YOUR URL',
type: 'post',
dataType: 'json',
data: {
'POST1': 'variable',
'POST2': 'variable'
},
success: function(data) {
alert(data.array1);
}
});
And on your PHP file
if (isset($_POST['POST1'])) {
//'DO SOME THING';
json_encode(array(array1=>'bla bla',array2=>'ble ble'));
}
