PHP Output Buffering

Posted by: admin July 12, 2020 Leave a comment


What are the methods to turn on output buffering either within a PHP script or using and htaccess file?

I use the following method in an htaccess file in the root of my application:

php_value output_buffering On
php_value output_handler mb_output_handler

On one of my shared hosting accounts (linux hosting with PHP 5.2.x), the above yields a blank page. Tech support says they can’t turn it on in the php.ini file but I can turn it on in my script…

ob_start() and ob_end_flush() also yields the same result. What can I do?

How to&Answers:

Use ob_start() and ob_end_flush().

ob_start() at the start of the script before any output (not even an empty space).

When u want to output use ob_end_flush().


Check your PHP.ini file and ensure the Output Buffer is enabled.

After that, you can use ob_start() whenever you want to begin buffering and ob_flush() to flush the buffer whenever you want to stop buffering.
