What are the best practices for creating symlinks in PHP to ensure proper functionality and compatibility with different file systems?

When creating symlinks in PHP, it is important to ensure proper functionality and compatibility with different file systems. One best practice is to use the `symlink()` function provided by PHP, which creates a symbolic link to the target file or directory. Additionally, it is crucial to check for errors when creating symlinks to handle any potential issues gracefully.

$target = '/path/to/target';
$link = '/path/to/link';

if (!symlink($target, $link)) {
    echo "Failed to create symlink";
    // handle error accordingly
} else {
    echo "Symlink created successfully";
}
