servercheck redirect
ik zit een beetje te puzzelen.
ik heb dit script, waarbij ik standaard wil kijken of in dit geval poort 200 van google openstaat en reageert.
wanneer deze online is zou die naar site1 moeten gaan op poort 80
is google offline in dit geval op poort 200, dan zou die naar site 2 moeten doorlinken op poort 80.
echter dat wil niet zo...
(oja google heb ik maar even als naam gebruikt net als de poortnummers.)
return_var
If the return_var argument is present along with the output argument, then the return status of the executed command will be written to this variable.
tnx voor de info.

Hey mensen.
Ik doe het toch eens proberen.
hier heb ik een upload script die checkt of een upload server online is.
daarbij kun je vele dingen checken van wat je wil uploaden.
wanneer die niet online is zal die kiezen voor een backup server na keuze.
Ik weet het is geen top10 script, maar heb mn best erop gedaan en ben er best blij mee..
ik heb het zelf niet geheel geschreven , alleen maar samengevoegd en aanpassingen gedaan.
Ik begin met de index.php

</div>
In bovenstaande roep ik dan de “servertest.php”aan.
Code (php)
En zoals je ziet word dan (afhankelijk of de eerste server online is) een van de twee servers aangeroepen om het bestand te uploaden.
