Accessing $vars from within a class

Urgent problem :s

[asantos]

Hi,

Im trying to get the $sql variable value from hello() in a()

function hello() {
 $sql = 'select * from table';
}

class ABC {
 function a() {
 // How can I access hello()'s $sql?
 }
}

Is there a way to do that? By referencing the variable or something like that?
Thanks, Andres

Just take the variable out of the function and leave it at the top. Or, just put global [us2.php.net] before the variable declaration. Good luck!

Or you could perhaps return [php.net] the value.

eelixduppy, thanks.
coopster, i cant, the function serves other processes with different needs.
