Datumsangabe in PHP anpassen

  • In PHP kann diese Einstellung Systemweit in der php.ini angepasst werden
  • oder direkt im Script mit
<?php setlocale(LC_TIME, 'de_DE.iso885915@euro'); echo date("l dS of F Y h:i:s A"); ?>
  • Testzeile um die Asgabe zu testen
<?php echo date("l dS of F Y h:i:s A"); ?>

Ausgabe in Datei schreiben

$ft = @fopen('/tmp/templog', 'a+')
or die("Kann Datei  /tmp/templog  nicht öffnen\n");
fwrite($ft, $commandLine);
fclose ($ft);

a+  schreibt anhängend
w   schreibt neu

IP Range vergleichen

if (strpos($_SERVER['REMOTE_ADDR'],"10.10.") !== false) {
  tu was;
} else {
  tu was anderes;

Error Reporting Manual

Im PHP-File

// Error Reporting komplett abschalten
error_reporting(0);

// Nur einfache Fehler melden
error_reporting(E_ERROR | E_WARNING | E_PARSE);

// E_NOTICE ist sinnvoll um uninitialisierte oder
// falsch geschriebene Variablen zu entdecken
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);
 
// Melde alle Fehler außer E_NOTICE
// Dies ist der Vorgabewert in php.ini
error_reporting(E_ALL ^ E_NOTICE);

// Melde alle PHP Fehler
error_reporting(E_ALL);

// Dies entspricht error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);
