Description

I'd like to suggest adding extended APC detection in
typo3/sysext/install/Classes/Configuration/ExtbaseObjectCache/ApcPreset.php

The reason: If like me, you've enabled APCu via PHP 5.5 but are running suPHP, you will be disappointed by the green "APC detected" message in the install tool.

APC is there, but it doesn't store anything between sessions, as suPHP doesn't allow that.

So there's a basic multi-request test for APC that would be more useful here:

 $var = apc_fetch('testvar');
 if ($var===false) $var=0;
 echo $var;
 apc_store('testvar', ++$var);

Run this twice, if the counter goes up, it's fine. If not: "APC is detected, but it's not working as supposed"

cf. http://stackoverflow.com/questions/27625563/apcu-and-suphp-possible

PS I mean it doesn't store anything between requests, not between sessions

If preset.isAvailable is true an AJAX based extra check should be done to verify that the values survive between requests. \TYPO3\CMS\Install\Configuration\ExtbaseObjectCache\ApcPreset::isAvailable() can store a value and the AJAX request can check if it is stored.

APC usually isn't used anymore since php 7, so v8 and above are not affected, the preset does not exist in v8 anymore. The issue is imho not severe enough to fix in v7, so I'll close the issue for now. If you think we should still change something in v7, please feel free to submit a patch to review.typo3.org.
