How can the use of phpinfo() help diagnose server-related PHP problems like the one described in the thread?

Issue: The PHP script is not functioning correctly on the server, possibly due to misconfigured PHP settings or missing extensions. Solution: Use phpinfo() to gather detailed information about the server's PHP configuration, including loaded extensions, configuration settings, and more. This can help identify any discrepancies or issues that may be causing the problem.

<?php
// Create a PHP script to output detailed server information using phpinfo()
phpinfo();
?>
