How can the use of output_buffer affect the display of forms on a web server when using PHP?

When using output_buffer in PHP, it can interfere with the proper rendering of forms on a web server by buffering the output before it is sent to the browser. This can cause issues such as forms not displaying correctly or not submitting data as expected. To solve this issue, you can simply turn off output buffering for the specific section of code where the form is being displayed by using the ob_end_flush() function to flush the output buffer. 

<?php
// Start output buffering
ob_start();

// Display form code here

// Flush output buffer to display form properly
ob_end_flush();
?>
