note 47808 added to function.join

ben dash xo at dubplates dot org is incorrect about split ~ split. If explode only deals with strings, whereas split allows regular expressions, split in PHP is approximately equivalent to split in Perl, while explode is never equivalent to Perl's split. In Perl, split takes from 0 to 3 arguments: PATTERN, EXPRESSION, and LIMIT. split splits the string EXPRESSION, using the regex PATTERN, up to LIMIT times. ---- Manual Page -- http://www.php.net/manual/en/function.join.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+47808 Delete -- http://master.php.net/manage/user-notes.php?action=delete+47808&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+47808&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+47808&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+47808&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+47808&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+47808&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+47808&report=yes Search -- http://master.php.net/manage/user-notes.php
