Global Scope:

Global scope is a variable which declared outside a function and can only be accessed outside a function.

Example :

<?php

$x = 5; // global scope

function mindstick() {

    echo "<p>Variable x inside function is: $x</p>";

} 

mindstick();

echo "<p>Variable x outside function is: $x</p>";

?>

Local Scope:

A variable declared within a function has a LOCAL SCOPE and can only be accessed within that function.

Example :

<?php

function mindstick() {

    $x = 5; // local scope

    echo "<p>Variable x inside function is: $x</p>";

} 

mindstick();

echo "<p>Variable x outside function is: $x</p>";

?>
