  PHP 过滤,替换 超链接

#过滤掉超链接

ereg_replace("<a [^>]*>|<\/a>","",$content);

#清除包含指定关键词的超链接

$find="this string is my find";$string=&#39;<font color="red">这段内容将要被替换掉</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);

//方法一

preg_match_all(&#39;/<(a|a)[s]{0,1}[w=":()]*>[nrn]*(check user)[nrn]*</(a|a)>/i&#39;,$string,$matches);
print_r($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
