[SOLVED] How to access variables declared outside a function from a function?

[obay]

$myvar = "hello";

function fxn() {
     /*[b]how do i access $myvar from here?
        excluding global variables and
        excluding passing variables on function call..
        help?? [/b]*/
}

fxn();

Maybe you can try to send the value to session and get from session ?

 

session_start();
$_SESSION['myvar'] = "hello";

function fxn(){
    echo $_SESSION['myvar'];
}

you should try and NOT use something that depends on state if you can. If there were no session because the user had cookies off then you would get NO joy from that.

 

keeping your code as free from state dependance is very good thing.

 

In this case you either pass the variable to teh function or you decalre the variable as global within the function...

 

<?php

$myvar = 'hello';

// passing the variable explicitly...
function fxn ($myvar)
{
echo $myvar;
}

// defining the variables scope from within the func...

function fxn ()
{
global $myvar;
echo $myvar;
}
?>

 

Pros and cons to each so you decide which fits your requirements best.
