Reading form post data

[nca]

Is there any way for a php script to be able to spit back what form variables and their data was sent to it?

script.php?variable=data&variable2=data2

for it to be able to echo back the line "variable=data&variable2=data2".

I am writing a script and do not always know what variables/data are going to be sent to it. But need to work with them.
