求教一简单正则?回帖给分!
电话号码字段(tel varchar类型)存储3个号码,并且是以分号结尾,类似:
0510-12323475,0781-26354589,021-25698746 (同时存储3个号码)
0521-25698745,, (有可能只存储1个电话号码)
0521-25698745,021-25698475, (有可能只存储2个电话号码)
现在用正则判断电话号码输入是否正常,注意电话区号。
RegTel=/^(\d{3,4}-\d{7,8}(-\d{1,4})?)?$/这是我写的,但是不行。

------解决方案--------------------

PHP code
$str = '0510-12323475,,';$pattern = '/,?\d{4}-\d+,?/';var_dump(preg_match($pattern, $str));<br><font color="#e78608">------解决方案--------------------</font><br>

老大,我只要$pattern的正则。但是你的$pattern不行。
