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 possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

Please check the code

We need a short and clear reproduce case.
The one you're reffering to is certainly not short.

I reduce the codes,

Please, nobody will look into this before you have a SHORT script. Short == less than 20 lines..
