正则严格验证身份证信息，严格验证身份证信息_PHP教程

<span>$a</span> = '130424770827005'<span>;

</span><span>$reg18</span> = '/[1-9]\d{5}(((1[9|8])\d{2})|(20[0-1]\d))((0\d)|(1[0-2]))(([0|1|2]\d)|3[0-1])\d{3}([0-9]|X)/'<span>;
</span><span>$reg15</span> = '/[1-9]\d{7}((0\d)|(1[0-2]))(([0|1|2]\d)|3[0-1])\d{3}/'<span>;
问题是对年份进行了判断从1800到2019<br />等4年就需要修改。<br />其实还可以更严格些。
</span><span>preg_match</span>(<span>$reg15</span>,<span>$a</span>,<span>$mm</span><span>);
</span><span>var_dump</span>(<span>$mm</span><span>);
