What are common error codes encountered when using symlinks in PHP, and how can they be resolved?

Common error codes encountered when using symlinks in PHP include "Permission denied" and "No such file or directory". These errors can be resolved by ensuring that the symlink target exists and that the PHP script has the necessary permissions to access it.

// Example code to resolve symlink errors by checking target existence and permissions
$symlink = '/path/to/symlink';
$target = '/path/to/target';

if (file_exists($symlink) && is_link($symlink) && file_exists(readlink($symlink))) {
    // Symlink target exists, proceed with accessing it
    $contents = file_get_contents($symlink);
    echo $contents;
} else {
    // Symlink or target does not exist, handle error accordingly
    echo "Symlink or target does not exist.";
}
