$path = '/var/www/html/myfile.txt'; if (t3lib_div::isAllowedAbsPath($path)) { // do something with the file } else { // the path is not allowed, throw an error or do some other action }
$path = '../../../myfile.txt'; if (t3lib_div::isAllowedAbsPath($path)) { // do something with the file } else { // the path is not allowed, throw an error or do some other action }In this example, we are checking if the path `../../../myfile.txt` is allowed or not. Notice that this path goes up two levels from the current directory, which could be a security concern if not properly checked. As for the package library, t3lib_div is part of TYPO3 CMS, which is an open-source content management system built with PHP.
