Description:
------------
When you use the variable $row in an for iteration or foreach the last element ech time become the current element and at end of iteration become empty. I think is an issue about the name of variable but nobody knows that, maybe you can introduce a warning in the documentation or resolve this problem

Test script:
---------------
$jsonString = '{"head":["Vehicle Name","2015-10-05","2015-10-06","2015-10-07","2015-10-08","2015-10-09","2015-10-13","2015-10-15","2015-10-16","2015-10-17","2015-10-18","2015-10-19"],"body":[[["V CLASS","1"],["40","","6","2015-10-05"],["41","prova2_2 prova2_2","2","2015-10-06"],["64","","2","2015-10-07"],["65","","2","2015-10-08"],["66","","2","2015-10-09"],["69","","2","2015-10-13"],["35","","6","2015-10-15"],["36","","6","2015-10-16"],["37","","6","2015-10-17"],["38","","6","2015-10-18"],["39","","6","2015-10-19"]],[["CARAVELLE[AB123CD]","2"],["","","","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["4","Driver_6 Driver_6","8","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["MAGELYS","5"],["42","driverFront office","54","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["","","","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["NN","12"],["70","Autista 2 driver 2.0","25","2015-10-05"],["","","","2015-10-06"],["71","","6","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["49","prova_3 prova_3","25","2015-10-15"],["","","","2015-10-16"],["48","","25","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["NN","16"],["50","prova asdasd","25","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["","","","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["E CLASS","17"],["","","","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["55","","2","2015-10-13"],["57","","2","2015-10-15"],["58","","2","2015-10-16"],["59","","2","2015-10-17"],["60","","2","2015-10-18"],["61","","2","2015-10-19"]],[["E CLASS","19"],["","","","2015-10-05"],["51","","3","2015-10-06"],["52","","3","2015-10-07"],["53","","3","2015-10-08"],["54","","3","2015-10-09"],["","","","2015-10-13"],["","","","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["V CLASS","25"],["","","","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["","","","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["S CLASS","30"],["","","","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["","","","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["VIANO","31"],["","","","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["","","","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["S CLASS","33"],["","","","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["","","","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["SPRINTER","34"],["","","","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["","","","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["prova_1","35"],["","","","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["","","","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["S CLASS","37"],["","","","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["","","","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]],[["CARAVELLE","38"],["","","","2015-10-05"],["","","","2015-10-06"],["","","","2015-10-07"],["","","","2015-10-08"],["","","","2015-10-09"],["","","","2015-10-13"],["","","","2015-10-15"],["","","","2015-10-16"],["","","","2015-10-17"],["","","","2015-10-18"],["","","","2015-10-19"]]],"total":"15"}';

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.

Hi, I don't know how modify this test script but is all an php script so you can surround it with php tag and it works.
 [2015-11-05 09:17 UTC] requinix@php.net 
Yeah. It works. That's the problem. Check the link I gave.

Can't fix whatever bug you're trying to report if you can't show us a SHORT script that demonstrates it.
