How to cancel hypertext link in php

在php编程中,有时需要对一些html文本进行处理,比如需要将文本中的超链接内容去除,此时就需要用到正则表达式了。

可以使用:

$str = preg_replace("/<a[^>]*href=[^>]*>|<\/[^a]*a[^>]*>/i","",$strhtml);

下面来看几个PHP正则表达式清除超链接文本的例了。(推荐学习:PHP编程从入门到精通

删除内容中的超链接

<?php
ereg_replace(&#39;<a([^>]*)>([^<]*)</a>&#39;,&#39;<font color="red">\\2</font>&#39;,$content);
ereg_replace("<a [^>]*>|<\/a>","",$content);

消除包含特定词的超链接

<?php
$find="this string is my find";
$string=&#39;<font color="red">替换掉了</font>&#39;;//将超链接替换成的内容
echo ereg_replace(&#39;<a([^>]*)>([^<]*&#39;.$find.&#39;[^>]*)</a>&#39;,&#39;<font color="red">\\2</font>&#39;,$content);

获取超链接文本内容

<?php
//方法一
preg_match_all(&#39;/<(a|a)[s]{0,1}[w=":()]*>[nrn]*(check user)[nrn]*</(a|a)>/i&#39;,$string,$matches);
//方法二
preg_match_all(&#39;/<a[dd]*>check user</a>/i&#39;,$string,$matches);
print_r($matches);
//方法三
preg_match_all(&#39;/<a[^>]*>[^<]*</a>/i&#39;,$string,$matches);
print_r($matches);
//方法四
preg_match_all(&#39;/<a.+?>check user</a>/is&#39;,$str,$arr);
print_r($arr);
//方法五
preg_match_all(&#39;/<a.+?>check user</a>/is&#39;,$str,$arr);
print_r($arr);
