Fehlerseite zur Behandlung aller Fehler

Dies ist eine Möglichkeit, eine einzige Fehlerseite für alle Fehler zu erstellen, die einfacher zu aktualisieren und zu pflegen ist.

1) Richten Sie alle Fehlerseiten in Ihrer .htaccess-Datei auf einen Ort aus

ErrorDocument 400 /error.php
ErrorDocument 401 /error.php
ErrorDocument 403 /error.php
ErrorDocument 404 /error.php
ErrorDocument 500 /error.php
etc.

2) PHP für error.php-Seite im Stammverzeichnis

$status = $_SERVER['REDIRECT_STATUS'];
$codes = array(
       403 => array('403 Forbidden', 'The server has refused to fulfill your request.'),
       404 => array('404 Not Found', 'The document/file requested was not found on this server.'),
       405 => array('405 Method Not Allowed', 'The method specified in the Request-Line is not allowed for the specified resource.'),
       408 => array('408 Request Timeout', 'Your browser failed to send a request in the time allowed by the server.'),
       500 => array('500 Internal Server Error', 'The request was unsuccessful due to an unexpected condition encountered by the server.'),
       502 => array('502 Bad Gateway', 'The server received an invalid response from the upstream server while trying to fulfill the request.'),
       504 => array('504 Gateway Timeout', 'The upstream server failed to send a request in the time allowed by the server.'),
);

$title = $codes[$status][0];
$message = $codes[$status][1];
if ($title == false || strlen($status) != 3) {
       $message = 'Please supply a valid status code.';
}
// Insert headers here
echo '<h1>'.$title.'</h1>
<p>'.$message.'</p>';
// Insert footer here
