Trouble

<?php
$variable = end($array);
$variable++;

I have the same issue when trying to update global variables within function.
Here is sample snippet to reproduce problem:

<?php
function test() {

    global $scripts, $styles;

    $scripts = new Scripts();
    $styles = new Styles();

}

And result:

--
vscode 1.31.1
os x 10.11.6
intelephense 1.0.4

@xiaohuilam should $last be considered used though? In the example it's just a variable that gets declared then incremented.

$last ++;

means

$last = $last + 1;

Right, I see it fails in cases like this.

function fn() {
    $i = 0;
    return ++$i;
}

Similar problem with array.

<?php
function test() {

    $array = array();
    $array['one'] = 1;
    $array['two'] = 2;

}
