# Apc
This module interacts with the [Alternative PHP Cache (APC)](http://php.net/manual/en/intro.apcu.php)
using either _APCu_ or _APC_ extension.
Performs a cleanup by flushing all values after each test run.

## Actions
### dontSeeInApc
Checks item in APC(u) doesn't exist or is the same as expected.
Examples:
``` php
<?php
// With only one argument, only checks the key does not exist
$I->dontSeeInApc('users_count');
// Checks a 'users_count' exists does not exist or its value is not the one provided
$I->dontSeeInApc('users_count', 200);
?>
```
* `param string|string[]` $key
* `param mixed` $value
### flushApc
Clears the APC(u) cache
### grabValueFromApc
Grabs value from APC(u) by key.
Example:
``` php
<?php
$users_count = $I->grabValueFromApc('users_count');
?>
```
* `param string|string[]` $key
### haveInApc
Stores an item `$value` with `$key` on the APC(u).
Examples:
```php
<?php
// Array
$I->haveInApc('users', ['name' => 'miles', 'email' => 'miles@davis.com']);
// Object
$I->haveInApc('user', UserRepository::findFirst());
// Key as array of 'key => value'
$entries = [];
$entries['key1'] = 'value1';
$entries['key2'] = 'value2';
$entries['key3'] = ['value3a','value3b'];
$entries['key4'] = 4;
$I->haveInApc($entries, null);
?>
```
* `param string|array` $key
* `param mixed` $value
* `param int` $expiration
### seeInApc
Checks item in APC(u) exists and the same as expected.
Examples:
``` php
<?php
// With only one argument, only checks the key exists
$I->seeInApc('users_count');
// Checks a 'users_count' exists and has the value 200
$I->seeInApc('users_count', 200);
?>
```
* `param string|string[]` $key
* `param mixed` $value
