分享一个php过滤字符串函数，具体代码如下：
function StripHTML($string){<br />$pattern=array ("'<script[^>]*?>.*?</script>'si", "'<style[^>]*?>.*?</style>'si", "'<[\/\!]*?[^<>]*?>'si", "'([\r\n])[\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");<br />$replace=array ('', '', "\\1", '', "&", "<", ">", ' ', chr(161), chr(162), chr(163), chr(169), "chr(\\1)");<br />return preg_replace ($pattern, $replace, $str);<br />}
