What are potential reasons for PHP pages to work correctly on a web hosting server but not on a local machine, even after troubleshooting steps have been taken?

The issue could be related to differences in server configurations between the local machine and the web hosting server. This could include differences in PHP versions, extensions, or settings. To solve this issue, ensure that the local development environment mirrors the configuration of the web hosting server as closely as possible.

// Example code snippet to check PHP version
if (version_compare(PHP_VERSION, '7.0.0') < 0) {
    echo 'PHP version 7.0.0 or higher is required';
    exit;
}
