In simple terms what is a Variable Scope (global)

Variable scope isn't a type of a variable. It actually describes where the variable was declared. You can think of it as a location of the variable. If a variable is defined inside a function, then it's only accessible in that function. This is known as function scope. Any variable defined outside of a function is defined in global scope. Such variables are accessible anywhere in the file, but not inside any of the functions.

Does that make sense?

Of course. Here's an example:

<?php

$globalScopeVar = 'I am in global scope.';

function someFunction() {
    $funcScopeVar = 'I am in function scope.';

    echo $globalScopeVar;  // will not work

    echo $funcScopeVar;  // outputs 'I am in function scope.'
}

echo $globalScopeVar;  // outputs 'I am in global scope.'

echo $funcScopeVar;  // will not work
?>

yes it does but can you give me example how that might look like you don't have to go in depth of labeling things or any thing like that just saying that will be really appreciated.
