Can any one suggest me what's wrong in it?

Answer 1

You should check if the zlib library loaded then clean the turn off output buffering by doing ob_end_clean()
You can add this line in the top of your file : <?php if (extension_loaded('zlib')){ ob_end_clean(); ob_start('ob_gzhandler');} ?>

Answer 2

Search line below in your php.ini file:

zlib.output_compression = On

change for:

zlib.output_compression = Off
