[SOLVED] Variables

[Azu]

Please tell me what is a simple way to make all variables global everywhere? So that when I declare a variable somewhere in my script it will work everywhere without me having to write "global $variablea,$variable1,$variablex,$variableblablablabla,$grrrrr,$zomg,$wtf,$asdf,$varrrriiibbbllle;" in every single function which is annoying as hell?

 

Oh and I've tried using the $globals array but it doesn't work on my server so I can't use that.

 

 

P.S. my arrays and objects also need to work everywhere

Pass your variables as parameters instead.

 

function foo($foobar)
{
   echo '<b>' . $foobar . '</b>';
}

$bar = 'hello!';

foobar($bar);

 

If you have lots of variables to parse to the function then add them into an array instead.

If $GLOBALS['variable1'] doesn't work, there is no way other than listing out your globals or passing them into the function as wildteen suggested. Function scope is there for a design reason and a technical reason, I'd suggest using OOP if you want functions that can share variables

With non-arrays and objects, you can make them constants. Otherwise, you'll have to use the above suggestions

[kenrbnsn]

Every variable that is defined is put into the $GLOBALS superglobal array and can be referenced that way:

<?php
function somefunc($var) {
echo "Passed variable: $var<br>";
echo 'Global var $somevar = ' . $GLOBALS['somevar'] . '<br>';
}

$somevar = 'This is a test';
somefunc('This is a passed value');
?>

I still would have to go through every single function and change them all though.

 

Isn't there a way to just remove the function scope or whatever? And what is "OOP"?

OOP = object oriented programming

 

And no, you can't just remove function scope, every running function is added to the stack and that function's frame holds it's own variables, you cant seperate the variables from the stack like you want unless you use OOP where the instance variables are stored in the heap...

 

This is assuming I remembered everything correctly and PHP does it like java/c/other languages (correct please jesi? I probably said something wrong)

[Azu]

Oh okay thanks.

 

Can you please tell me how to enable OOP?

[genericnumber1]

it's not something you enable.

but it's a bit much if you just want to overcome variable scope.

Okay thanks. I guess there isn't any way to get them working without rewriting all my code.
