Regular expression for mobile phone number verification in php_PHP tutorial

I have collected two mobile phone number verification codes. One is to use jquery verification at the front desk and then use the backend php tutorial code to verify whether the mobile phone number is legal. I hope it will be useful to everyone.
I use jquery.validate.js for the front-end code, the code is as follows:

JavaScript code

This is just an imprecise verification and can only be roughly verified to a certain range, so the focus is still behind.

PHP code

$mobilephone=trim($_POST["smMobilePhone"]);
//Regular verification of mobile phone number
if(preg_match("/^13[0-9]{1}[0-9]{8}$|15[0189]{1}[0-9]{8}$|189[0-9]{ 8}$/",$mobilephone)){
//Verification passed
                             
}else{
//Mobile phone number format is incorrect
                             

//regular expression
$tel = "15558530459"; //The author's mobile phone number. If you have any questions, you can contact me by phone or QQ. My QQ is mezongzi@qq.com
if(strlen($tel) == "11")
{
//The above part determines whether the length is 11 digits
$n = preg_match_all("/13[123569]{1}d{8}|15[1235689]d{8}|188d{8}/",$tel,$array);

* 151,152,153,156,158.159 starts with any 8 number

* /")*/

var_dump($array); //See if it is found. If found, the phone number will be output

}else
{
echo "The length must be 11 digits";
}

* If there is a better one, you can post it and share the happiness!
