Code wird doppelt ausgeführt - warum?

[Der Markus]

Schreib doch da mal den Inhalt des $_SERVER-Arrays rein:

fputs($fp, print_r($_SERVER, 1));

Dann kannst du dir ansehen, welche Requests (nebst Referrer und so weiter) dieses Script erreicht haben.

Hab ich gemacht, das ist das Ergebnis:

Offenbar wird die ganze Seite doppelt aufgerufen. Stutzig macht mich     [REMOTE_PORT] => 4972 und beim nächsten mal ein anderer Port. Dürfte also einen gänzlich anderen Grund haben.
