How can PHP be used to create a central page that checks and displays the current version of a CMS on different installations?

To create a central page that checks and displays the current version of a CMS on different installations, you can use PHP to make HTTP requests to each CMS installation, retrieve the version information, and display it on the central page. This can be achieved by creating a PHP script that loops through a list of CMS URLs, sends a request to each URL, parses the version information from the response, and then displays it on the central page. 

<?php
// List of CMS URLs
$cms_urls = array(
    'http://example.com/cms1',
    'http://example.com/cms2',
    'http://example.com/cms3'
);

// Loop through each CMS URL
foreach ($cms_urls as $url) {
    $response = file_get_contents($url);
    // Parse version information from the response
    preg_match('/<meta name="version" content="([^"]+)"\/>/', $response, $matches);
    $version = isset($matches[1]) ? $matches[1] : 'Version not found';
    // Display version information
    echo "CMS at $url is running version $version <br>";
}
?>
