<?php
echo "Let's do something with success", PHP_EOL;

apcu_store('anumber', 42);

echo
apcu_fetch('anumber'), PHP_EOL;

echo
apcu_inc('anumber'), PHP_EOL;
echo
apcu_inc('anumber', 10), PHP_EOL;
echo
apcu_inc('anumber', 10, $success), PHP_EOL;

var_dump($success);

echo
"Now, let's fail", PHP_EOL, PHP_EOL;

apcu_store('astring', 'foo');

$ret = apcu_inc('astring', 1, $fail);

var_dump($ret);
var_dump($fail);
