Ping

Door Erik Rijk -06-10-2005 00:00 -4.699 views

Het script is niet door mij zelf gemaakt maar ik wilde het even delen omdat het een prima en waarschijnlijk handig script is. Via het script kan je een ping commando uitvoeren, dus je hoeft niet eerst via dos te gaan. Het niveau voor het script is gevorderd het is wel te gebruiken voor een beginner maar lastig aan te passen omdat sommige functies waarschijnlijk nog niet bekend zijn bij beginnende php'ers

        // Remove any slashes if Magic Quotes GPC is enabled.

        // Create arrays.

        $ping_count_array = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 25); // Ping count
