1: Globals are bad...m'kay.
You should never use globals. If your function needs a variable, you should
pass it in. There are exceptions to this rule but it's not a good idea to
program normally this way.
2: Is this a form?
It sounds (from the way you word it) that the variables are part of a form.
If so, pass $_POST into your form and it will be able to evaluate them. If
it's METHOD=GET then use $_GET. This is also a much more generic way to
program since if you add a new variable to the form, you don't have to make
it global in this function.
if (myFunction($_GET)){
echo "Everything is hunky dory!";
} else {
echo "Blow Chow";
}
function myFunction($formArray=null){
if (isNull($formArray){
return false;
}
if (isarray($formArray)){
return true;
} else {
return false;
}
} // function myFunction($formArray=null)
WARNING: I have not tried the code above. Use at your own risk. But the
concepts are there.

avalible to a function, i'm doing an eval inside, so i need all the
