[TYPO3-core] RFC: #13670: Performance optimization: change while(list() to foreach()

[Georg Ringer]

Hi,

This is an SVN patch request.

Type: Bugfix, Performance tuning

Bugtracker references:
http://bugs.typo3.org/view.php?id=13670

Branches: trunk, 4.3

Problem:
foreach($arr as $key=>$value) is faster than while (list($key,
$value)=each($arr)) so it should be changed

Solution:
change it

Georg
