simple question - php variables

[mfacer]

this is probably a very simple question... but how do I (if possible) set a variable and use it within a function...?
eg:

$variable = "Matt";

function myFunction() {
 echo $variable;
}

it throws a wobbler!
How can I access it?

[vaaaska]

$variable = "Matt"; 

function myFunction() { 
global $variable;
echo $variable; 
}

excellent - many thanks!! 🙂

If that function always needs that variable you really should pass it to the function when you call it -- ie

myFunction($variable);

Your function would look like:

function myFunction($mylocalcopy) {
   echo $mylocalcopy;
}

that's usually how I do it in the past - but this is one file which needs configuration variables set at the top - its a plugin for some blog software - so to run it as one file is much easier 🙂

cheers for all the advice etc 🙂
