How can the settings in Plesk software affect the display of PHP pages on a website?

The settings in Plesk software can affect the display of PHP pages on a website by controlling PHP version, modules, and configurations. If PHP pages are not displaying correctly, it may be due to incompatible settings in Plesk. To fix this issue, ensure that the PHP version and settings in Plesk are compatible with the PHP code used on the website.

// Example PHP code snippet to check PHP version
if (version_compare(PHP_VERSION, '7.0.0') >= 0) {
    // PHP code compatible with PHP 7 and above
} else {
    // Display a message or handle the compatibility issue
}
