$str=<<<EOF
<a class="rich_media_meta rich_media_meta_link rich_media_meta_nickname" href="javascript:void(0);" id="post-user">做个会搭配的女子</a>
<a class="rich_media_meta rich_media_meta_link rich_media_meta_nickname" href="javascript:void(0);" id="post-user">美国际劳动节</a>
<a class="rich_media_meta rich_media_meta_link rich_media_meta_nickname" href="javascript:void(0);" id="post-user">联通融</a>
<a class="rich_media_meta rich_media_meta_link rich_media_meta_nickname" href="javascript:void(0);" id="post-user">不知不觉才是美</a>
EOF;

    $res= preg_replace('/(<a .*>).*(<\/a>)/iU','$1$2',$str);

    var_mp($res);

文件的编码注意哦

可以使用正则表达式。

$str = <<<EOT
<a class="rich_media_meta rich_media_meta_link rich_media_meta_nickname" href="javascript:void(0);" id="post-user">做个会搭配的女子</a>
<a class="rich_media_meta rich_media_meta_link rich_media_meta_nickname" href="javascript:void(0);" id="post-user">美国际劳动节</a>
<a class="rich_media_meta rich_media_meta_link rich_media_meta_nickname" href="javascript:void(0);" id="post-user">联通融</a>
<a class="rich_media_meta rich_media_meta_link rich_media_meta_nickname" href="javascript:void(0);" id="post-user">不知不觉才是美</a>
EOT;

echo preg_replace('#(<a class="rich_media_meta rich_media_meta_link rich_media_meta_nickname" href="javascript:void$0$;" id="post-user">).*?(</a>)#', '$1替换成这个$2', $str);
