高分求一正则表达式，谢谢大家。

Question

<?php
$content = "<font color='red'>字符串</font>";$new_content = preg_replace("/<[^>]+>/", "", $content);echo $new_content;
?>

Answer 1

根本不用正则啊, 用正则反而容易出错.$content = strip_tags"<font color='red'>字符串</font>";你试试看.

Answer 2

$content = strip_tags("<font color='red'>字符串</font>");// strip_tags(): 去掉 html 标签仅留文本.

Answer 3

$search = array ("'<script[^>]*?>.*?</script>'si",  // 去掉 javascript
                 "'<[\/\!]*?[^<>]*?>'si",           // 去掉 HTML 标记
                 "'([\r\n])[\s]+'",                 // 去掉空白字符
                 "'&(quot|#34);'i",                 // 替换 HTML 实体
                 "'&(amp|#38);'i",
                 "'&(lt|#60);'i",
                 "'&(gt|#62);'i",
                 "'&(nbsp|#160);'i",
                 "'&(iexcl|#161);'i",
                 "'&(cent|#162);'i",
                 "'&(pound|#163);'i",
                 "'&(copy|#169);'i",
                 "'&#(\d+);'e");                    // 作为 PHP 代码运行$replace = array ("",
                  "",
                  "\\1",
                  "\"",
                  "&",
                  "<",
                  ">",
                  " ",
                  chr(161),
                  chr(162),
                  chr(163),
                  chr(169),
                  "chr(\\1)");$text = preg_replace ($search, $replace, $document);php手册中的一个例子.
