Examples

Example #1 apcu_inc() example

`<?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),PHPEOL;vardump(success), PHP_EOL;var_dump(success),PHPE​OL;vard​ump(success);

echo

"Now, let's fail", PHP_EOL, PHP_EOL;apcu_store('astring', 'foo');$ret = apcu_inc('astring', 1, fail);vardump(fail);var_dump(fail);vard​ump(ret);
var_dump($fail);
?>`

The above example will output something similar to:

Let's do something with success 42 43 53 63 bool(true) Now, let's fail

bool(false) bool(false)
