function not detecting variable

Question

I currently have an index.php file and on the top i have

$pagetitle == "home";

function isThisHome(){
    if($pagetitle == "home"){
        $output = $output . 'this is home!';
    }else{
        $output = $output . 'this is not home!';
    }
    return $output;
}
echo isThisHome();

I'd expect that it would echo "this is home!" but instead it's echoing "this is not home!". Can someone help correct me to make it say "this is home"?

$pagetitle == "home";

Should be

$pagetitle = "home";

To access variables outside the scope of a function, you need to qualify the global variable with global qualifier inside the function.

Also the assignment operator is ASSIGN (=), so IS_EQUAL (==) is not the same.

$pagetitle = "home";

function isThisHome(){
    global $pagetitle; 
    if($pagetitle == "home"){
        $output = $output . 'this is home!';
    } else{
        $output = $output . 'this is not home!';
    }
    return $output;
}
echo isThisHome();

It is not about the variable scope. Please look at the question and code again. He used two `==` instead of 1 – Dacaspex Jan 09 '16 at 21:58
Yes, but he still has 2 problems. He's probably not seeing warnings because his `php.ini` file. – Ryan Jan 09 '16 at 21:58
