Function withn a function

[alecjw]

Could you use a function within a function eg:

<?php
function a()
{
//Some code
}
function b()
{
a()
//Some code
}
?>

Or would you need to make function a() global first?

Yes you can call a function within a function. However if you have a function defined within a function you first have to call the function that has the embeded function. Then you can call the emebed function. Like so:
[code=php:0]// define the function within a function
function foo() {
    function bar() {
        echo "foobar";
    }
}

//call foo first
foo();

// now you can use bar function
bar();[/code]
