note 24437 added to language.types.string

If you need to escape "$" to be escaped in the output, you need "\\\\$" - or maybe even more! $ is a control character in Latex. If you want it to become \$ for further processing through Latex, it seems that there must be 4 (!) backslashes - so that in the end there is one left after processing the string twice. Once through str_replace and once through preg_replace! Using 4.1.0 on Windows. -- http://www.php.net/manual/en/language.types.string.php http://master.php.net/manage/user-notes.php?action=edit+24437 http://master.php.net/manage/user-notes.php?action=delete+24437 http://master.php.net/manage/user-notes.php?action=reject+24437
