preg_replace(&#39;]*)>([^<]*)&#39;,&#39;\2&#39;,$content); 
preg_replace("]*>|","",$content);

 

2、消除包含特定词的超链接

 

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

 

3、获取超链接文本内容

 

//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;/check user/i&#39;,$string,$matches);   
print_r($matches);  
//方法三  
preg_match_all(&#39;/]*>[^<]*/i&#39;,$string,$matches);  
print_r($matches);  
//方法四  
preg_match_all(&#39;/check user/is&#39;,$str,$arr);
