Code

function _drupal_error_header($message, $type, $function, $file, $line) {
    // $number does not use drupal_static as it should not be reset
    // as it uniquely identifies each PHP error.
    static $number = 0;
    $assertion = [
        $message,
        $type,
        [
            'function' => $function,
            'file' => $file,
            'line' => $line,
        ],
    ];
    // For non-fatal errors (e.g. PHP notices) _drupal_log_error can be called
    // multiple times per request. In that case the response is typically
    // generated outside of the error handler, e.g., in a controller. As a
    // result it is not possible to use a Response object here but instead the
    // headers need to be emitted directly.
    header('X-Drupal-Assertion-' . $number . ': ' . rawurlencode(serialize($assertion)));
    $number++;
