Hello!! evryone,

I am little bit confuse with the two builtin functions of PHP

ob_start();

and

ob_end_flush();

As i am new to PHP. Kindly is there anyone who could help me in understanding the purpose of these functions?? And is it necessary to add them in every page or not??

Regards,

both are buffer calls the first
ob_start(); creates a buffer, this gives you more flexablity over the final output as it can be edited that even includes cookies, you can call ob_get_contents() to retrive the buffers content.

ob_end_flush(); Ends the buffer (deletes it) and prints it to screen.
