Now I want to know how to store this image on server

Answer 1

imagepng() has a second parameter which is the filename.

See

http://www.php.net/manual/en/function.imagepng.php

bool imagepng ( resource $image [, string $filename [, int $quality [, int $filters ]]] )

filename

The path to save the file to. If not set or NULL, the raw image stream will be outputted directly.

Note:

NULL is invalid if the quality and filters arguments are not used.
