Question

Language is PHP 5.4 on an Apache 2.2 server. It’s a script being called by ajax.

$usr = new User();

function getMyName(){
    echo $usr->username;
}
getMyName();

For some reason $name is out of scope. Why would that be the case? I also tried directly calling the script with the same result. I tried use($name) to resolve, but that apparently only works with anonymous functions (closures)?

When I do this, it works but it’s ridiculous:

$usr = new User();
$name = $usr->username;

function getMyName($n){
    echo $n;
}
getMyName($name);

Answer 1

$usr = new User();

function getMyName(){
    global $usr;
    echo $usr->username;
}
getMyName();

alternatively:

$usr = new User();

function getMyName($usr){
    echo $usr->username;
}
getMyName($usr);
