PHP clean or normalize html text -

it seems question not asked, that's why asking me.

i have chunk of html code when in <textarea> tag created wysiwyg editor.

now before saving, on form submit, normalize text inside removing unneccessary whitespaces/spaces, have code formated tabs, etc.

here code:

27 Июня                  17:51:58                                                                                                                       Познакомлюсь с девчонками из прибалтики                                                 Категория: Знакомства > Контакты по интересам                                       Просмотров: 7 

i wish text going in 1 row (single lined), correct use of spaces, dots etc. possible somehow php without need write function ?

sanitizing text never task composed of 1 line of text, i'm afraid. however, procedures common simple cleansing. example, $output = preg_replace("/\s+/", " ", $input); rid of excess whitespaces worry lot more possible malicious code injections through <textarea> element.

maybe should give htmlpurifier look, it's quite complete if it's still not html5 compliant. sort out majority of concerns filtered content.

hope helps :)
