Duplicate entries in localconf.php

It is possible to have duplicate entries with different values in typo3conf/localconf.php. Why this happens ?

You don't need to worry about this phenomenon because TYPO3 will use always the last option, this is not a dangerous situation but may be confusing to inexperienced users.

Regarding the cause, usually TYPO3 will update existing entries without duplication only if they were quoted using an apostrophe. If double quotation marks are used TYPO3 will make a new entry using apostrophes at the end of the file.

It is also possible that some of the entries have been added manually. This is also not a problem as TYPO3 will use always the last option in the file.
