$url = 'http://example.com'; $content = t3lib_div::getUrl($url); if ($content !== false) { echo $content; } else { echo 'Unable to retrieve content.'; }
$url = 'https://example.com/sitemap.xml'; $xml = t3lib_div::getUrl($url); if ($xml !== false) { $data = simplexml_load_string($xml); // Process the XML data } else { echo 'Unable to retrieve content.'; }
$url = 'ftp://example.com/file.pdf'; $file = t3lib_div::getUrl($url); if ($file !== false) { file_put_contents('/path/to/file.pdf', $file); } else { echo 'Unable to retrieve content.'; }Brief Explanation: In the first example, we retrieve the content of a website using the `http` protocol and print it. In the second example, we retrieve an XML file from a server using the `https` protocol and process it using SimpleXML. In the third example, we retrieve a file using the `ftp` protocol and save it to the local file system. We can see that `t3lib_div::getUrl()` method can be used to retrieve content from various protocols in PHP. Package Library: The `t3lib_div` is a part of TYPO3 CMS which is a popular content management system written in PHP. This library provides various utility functions that can be used in TYPO3 extensions or in standalone PHP scripts.
