[英]PHP regex for specific phone number format
im trying to validate phone number in php. 我试图验证电话号码在PHP中。 The requirements are (0d)dddddddd or 0d dddddddd where d is 0-9.
要求为(0d)dddddddd或0d dddddddd,其中d为0-9。 This is what I have right now
这就是我现在所拥有的
if(!preg_match("/^0[0-9]{9}$/", $phone))
{
//wrong format
}
I have tried several similar questions, but still cant understand regex very well. 我已经尝试了几个类似的问题,但仍然不能很好地理解正则表达式。 Can anyone help me fix the regex?
谁能帮我修复正则表达式?
You could try the below code, 您可以尝试以下代码,
if(!preg_match("~^(?:0\d\s|\(0\d\))\d{8}$~", $phone))
{
//wrong format
}
Explanation: 说明:
^ the beginning of the string
(?: group, but do not capture:
0 '0'
\d digits (0-9)
\s whitespace
| OR
\( '('
0 '0'
\d digits (0-9)
\) ')'
) end of grouping
\d{8} digits (0-9) (8 times)
$ before an optional \n, and the end of the
string
^(?:\(0\d\)|0\d\s)\d{8}$
Try this.See demo. 试试看。看演示。
