PHP matches the phone number, mobile phone number, 400 number function, and regular expression. Very useful.

If PHP matches the telephone expression correctly, write it by yourself. 1. If it is a phone number, there must be a horizontal bar between the area code and the phone number, and there must be area code 2. If it is a mobile phone number, mobile phones can be prefixed with "86", "86", "86-", and "86-" 3. The phone number can only match those in mainland China. There are three digits at the beginning of 02, and only 010 Beijing No. 4 at the beginning of 01 is supported.
