Allow variables to be accessed outside a function

[bubbles19518]

So I have a result that is defined out side of a function in a script. Both the result and the function are inside the same page, but the function is unable to access the result. How do I allow the function to use the variable, without defining it inside the function?

pass it to the function as an argument

You can use the global statement, but it's kind of a no-no (it's bad design generally because it indicates you are not heeding rules of scope).

Better would be to pass the variable to the function.


$var = 'yay';
$funcResult = execFancyFunc($var);
echo $funcResult;

function execFancyFunc($funcVar) {
if ($funcVar == 'yay') {
return "You are so cool!";
}
}
