再求一个正则
比如我有
......(略)
...(略)
....(略)
......(略)
(105)我只要其中 class=cnt 的span,并且只要105这个数字;请问该如何写?
------解决方案--------------------
得到 数组 foo 之后做个判断,万一没有匹配内容的话直接输出会有出错提示.
PHP code
$str = '<span class="cnt">(105)</span>';
preg_match ( '/<span class="cnt">.*\(([\d]+)\)/', $str, $foo );
$bar=isset ($foo[1])? $foo[1]:'';
echo $bar; <div class="clear">
</div></span>
