Wrong Memory value #1136

In the 2nd page of installation, I can read:
Limite mmoire 5242880M
(memory limit)

My php.ini is as follow:
memory_limit = 52428800

It's another way to fill the data, by specifing bytes only. So the formula isn't working here.

Page was: /piwik/index.php?action=systemCheck
Keywords: memory

(In [1820]) fixes #1136 - get memory limit expects setting in megabytes

if(substr($memory, -1) == 'K') <====== shouldn't it be k not K? Or the use of strtolower() on the value? Perhaps a switch() statement would be better here (even if performance on this script isn't really an issue).

Thanks for fixing the bug.
