Hello Thiago,
It means whether or not the key association is maintained. For
example:
$fruit = array('banana', 'orange', 'apple');
echo $fruit[0]; // banana
sort($fruit);
echo $fruit[0]; // apple
So sort() does not maintain the correlation between key and value.
That description should use simpler and less wordy English, but
don't go and look up who wrote it because SVN lies! ;)
Regards,
Philip
