What is the significance of the "SAFE MODE Restriction" in PHP and how can it affect opendir() function?

The "SAFE MODE Restriction" in PHP is a security feature that limits certain functions for security reasons. When in safe mode, the opendir() function may not be able to open directories outside of the specified safe directory. To work around this restriction, you can use the opendir() function in conjunction with the realpath() function to get the full path of the directory. 

$directory = '/path/to/directory';
$realpath = realpath($directory);

if ($realpath) {
    $handle = opendir($realpath);
    // Rest of your code to work with the directory
} else {
    echo "Invalid directory path";
}
