note 51209 modified in function.preg-split by danbrown

preg_split() behaves differently from perl's split() if the string ends with a delimiter. This perl snippet will print 5: my @a = split(/ /, "a b c d e "); print scalar @a; The corresponding php code prints 6: <?php print count(preg_split("/ /", "a b c d e ")); ?> This is not necessarily a bug (nowhere does the documentation say that preg_split() behaves the same as perl's split()) but it might surprise perl programmers. --was-- preg_split() behaves differently from perl's split() if the string ends with a delimiter.
