PHP phone number Regular expression test program code

The code is as follows	Copy Code
function Funcmtel ($STR)//mobile number Regular expression test { Return (Preg_match ("/(?: 13d{1}|15[03689]) d{8}$/", $str))? True:false; }

Test

18678785887

Return to

False

Cause analysis, see the discovery that the above is only validated with 13, 15, the beginning of the natural 18 is not available

After modification

The code is as follows	Copy Code
function Funcmtel ($STR)//mobile number Regular expression test { Return (Preg_match ("/(?: 1[3|4|5|8]d{1}|15[03689]) d{8}$/", $str))? True:false; }

Test

18678785887

Return to

True

That's the way it works.

Experience:

such as cell phone number is constantly updating the number of paragraphs, we write the function as a public function, so that we can solve the problem.
