[SOLVED] echo not working properly in functions

[WhiteCube]

hi all!

 

I've got this php script here.. but it doesn't seem to work when in a function!

 

<?php
$username = "sss";

  $exe = "users";
  $exe();
  
   function users()
  {  
    echo "username=$username";
  }
?>

 

While reading this.. it should echo out.. "username=ssss".. right?

 

But I keep getting

 

"username=" just that!!

 

Can someone tell me what's going on?

 

Thanks!

make $username global in your function

 

function users()
  {
global $username;
...

Or change the function so it takes a parameter:

 

function users ($name){

  echo "username=$name";

}

 

then use:

 

$exe($username);
