variables available to custom function.

atmorell

When I write a function I normally pas variables like this:

function test($var1) {
code...
}

How can I make all current variables available to that function? Without having to write them all into the function e.g. function($var1, var2.... var20) I am using the same function to all my pages - and have different variables on each page. I don't want to wirte them all 100 into the function! 😉

Best regards.

Dont. Such abuse of global variables is a Bad Thing.

That's the reason why you pass the values of those variables as arguments to the function. If necessary, use an array.

Maybe you also need to consider why you have 100+ variables in global scope. Seems like a code smell to me.

That was an example... I probably have 10 or less.

U can alway find your var, in GLOBAL array ....

$var = 1;
function _func() {
    echo $GLOBAL['var'];
}

This is not the right approach here. Really, as much as you have good intentions, think before advising others to commit suicide.

I know this, but he got a question, u don't know why he asked it or what is he's intention, I think u need to give him the answer to he's question and advise him if its good or bad, u make the advise I give him the answer, using it is only he's choice ...

Better yet, find out why the question is being asked first. Smarter to identify the real problem and try to fix it than just patching the symptoms. Saves having to deal with more problems later on.

Too often you end up discovering that the question they asked is not the one they wanted an answer to.

Besides, you didn't advise the poster that mindlessly using the $GLOBALS array was bad.
