Regular Expression - How to use regular expression to get the content of a tag in php?

<code><!-- 1 -->
＜a class="myclass" target="_blank" href="http://www.taobao.com/">我是内容1</a＞
<!-- 2 -->
＜a target="_blank" class="myclass" href="http://www.baidu.com/">我是内容2</a＞
<!-- 3 -->
＜a class="noclass" target="_blank" href="http://www.foobar.com/">不包含我</a＞
</code>

Like the tag above, I want to get the content of 1 and 2 of the a tag (I am content 1, I am content 2), but I don’t want 3 (not including me). The only difference between them is that the classtags are different classlocation may also be different! ! ! **

Thanks for the invitation.

<code class="php">$str = '＜a class="myclass" target="_blank" href="http://www.taobao.com/">我是内容1</a＞
＜a target="_blank" class="myclass" href="http://www.baidu.com/">我是内容2</a＞
＜a class="noclass" target="_blank" href="http://www.miyahuo.com/">不包含我</a＞';

preg_match_all('#＜a .*class="myclass".*>(.*)</a＞#', $str,$m);
print_r($m);
/*
Array
(
    [0] => Array
        (
