< p > Mit usleep() kann man ein Skript fü r eine angegebene Zeit in Mikrosekunden< br >
(micro_seconds) anhalten.< br >
Dabei wird die Zeit, die man angegeben hat, abgewartet und erst dann die< br >
Ausgabe zum Browser gesendet. Mö chte man Zeichenketten, die vor der< br >
Funktion usleep() ausgegeben wurden, direkt an den Browser senden, so< br >
mü ssen Sie zusä tzlich die Funktion flush() verwenden.< / p >
< p > Die Funktion usleep() wird auf einem Windows-System nichts bewirken,
da< br >
sie dort nicht unterstü tzt wird.< / p >

< p > Zu Beispiel 1:< br >
Bei diesem Beispiel werden die ersten beiden Zeichenkette mit echo an
den< br >
Browser ausgegeben und sind sofort fü r den User sichtbar. Danach
stoppt das< br >
Skript fü r genau 5 Sekunden und beginnt danach wieder die restliche< br >
Abarbeitung des Skripts. Dabei werden dann die beiden letzten Zeichenketten< br >
an den Browser gesendet.< / p >
< p > Zu Beispiel 2:< br >
Dieses Beispiel zeigt einen einfachen Countdown. Dabei werden im Abstand< br >
von 1 Sekunde die Zeichenketten an den Browser ausgegeben. Der User sieht< br >
dann im Sekundenabstand, wie der Countdown von 5 nach 1 runterzä hlt.< / p >
< p > Zu Beispiel 3:< br >
Bei dem dritten Beispiel wird das Skript fü r 5 Sekunden angehalten
und erst< br >
dann werden alle Zeichenketten (auch die, die vor der Funktion usleep()< br >
aufgerufen wurden) an den Browser gesendet.< / p >
