Local Variable
A local variable is a variable in a method or a function. It is in the local scope, and is not available anywhere else.
A local variable is created by assigning it a value in a method, using the static keyword, or using the extract() function. It might be removed by the unset() function.
<?php
function foo() {
$localVariable = 1;
// ... more code
}
function goo() {
// this variable is distinct from the one in foo()
$localVariable = 2;
// ... more code
}
?>
