Regular Expression for mobile phone number verification in php

Two cell phone number verification codes are added to the favorites. First, the front-end uses jquery to verify the validity of the mobile phone number with the background php tutorial code.
I use jquery. validate. js as the front-end Code. The Code is as follows:
 

JavaScript code

<Script type = "text/Webpage effects">
$ (Document). ready (function (){
$ ("# SmForm"). validate ({
Rules :{
SmMobilePhone :{
Required: true,
Digits: true,
Range: [13000000000,18999999999]
}
},
Messages :{
SmMobilePhone :{
Required: "You have not entered the mobile phone number ",
Digits: "the mobile phone number format is incorrect ",
Range: "The phone number length or format is incorrect ",
}
},
PreErrs :{

}
});
});
</Script>

This is just an inaccurate verification, and it can only be roughly verified to a specific range, so the focus is still on the future.

PHP code

$ Mobilephone = trim ($ _ POST ["smMobilePhone"]);
// Regular verification of mobile phone numbers
If (preg_match ("/^ 13 [0-9] {1} [0-9] {8} $ | 15 [0189] {1} [0-9] {8} $ | 189 [0-9] {8} $ /", $ mobilephone )){
// Verification passed

} Else {
// Incorrect Mobile Phone Number Format

}

Var_dump ($ array); // check whether it is found. If it is found, the phone number is output.
} Else

Echo "the length must be 11 characters ";
