What configuration setting in the php.ini file can control the buffering of PHP output?

To control the buffering of PHP output, you can adjust the "output_buffering" configuration setting in the php.ini file. By default, output buffering is set to "Off" which means that output is sent directly to the browser as it is generated. However, enabling output buffering can improve performance by allowing PHP to send all output at once after the script has finished executing.

// Enable output buffering in PHP script
ob_start();
