Code to clear HTML tags in strings under PHP_PHP Tutorial

This article introduces php to clear the html tags in the string
There are two methods to filter all html tags in the string. One is to write a function ourselves and use regular filtering, and the other is to use php's own function strip_tags.

Copy code The code is as follows:

function clear_html_label($html)
{
$search = array ("']*?>.*?'si", "'<[/!]*?[^<>]*?> 'si", "'([rn])[s]+'", "'&(quot|#34);'i", "'&(amp|#38);'i", "'&( lt|#60);'i", "'&(gt|#62);'i", "'&(nbsp|#160);'i", "'&(iexcl|#161);'i ", "'&(cent|#162);'i", "'&(pound|#163);'i", "'&(copy|#169);'i", "'(d+ );'e");
$replace = array ("", "", "1", """, "&", "<", ">", " ", chr(161) , chr(162), chr(163), chr(169), "chr(1)");

return preg_replace($search, $replace, $html);
