php question

Recommended Posts

it doesn't actually COMPILE it..


what it does is EXECUTE the PHP, then sends whatever PHP says to send, to the client





  echo "hi";



php will evaluate the PHP tag <? ... ?>


php will then go over the commands it encounters


echo "hi";


echo "hi"; just basically means "output: hi"


so thats the end,


then php sends the OUTPUT to the client


then the client gets the data, lables it HTML (in most cases, unless specified otherwise) then renders it..


it is only run once, and you cannot run it again after php has finished executing for that request
