How to verify mobile phone number in php_PHP tutorial

We have used PHP regular expressions to verify mobile phone numbers. The rule for mobile phone numbers is that the length is 11 digits and starts with 13, 15, 18, etc. We only need to classify and plan this to achieve perfect mobile phone number verification regular expressions. .

Everyone should have this common sense. Chinese mobile phone numbers all start with the number "1", and then use 11 digits composed of 10 digits "0~9"

Number combination, then our verification rules must be written based on this idea.
Based on the simple idea above, we can write the following verification code:

The code is as follows

Copy code

代码如下	复制代码
//本代码仅仅是提供一些思路       //距离实际应用还有一些距离        $mobile = '15858588585';       //下面的1便是手机的第一位数字必须为数字1       //[0-9]指后面的数字均为0~9的数字       //{9}这中间的9指的是手机号码除了第一位数外，其他要重复10次，刚好就是11位数了       if(!preg_match('/^1([0-9]{9})/',$mobile)) exit('您的手机号码不正确');       ?>

//This code is just to provide some ideas //There is still some distance from practical application

$mobile = '15858588585';

//The 1 below is the first digit of the mobile phone and must be the number 1

//[0-9] means that the following numbers are all numbers from 0 to 9

//{9}The 9 in the middle means that except for the first digit of the mobile phone number, the rest must be repeated 10 times, which is exactly 11 digits.

If(!preg_match('/^1([0-9]{9})/',$mobile)) exit('Your mobile phone number is incorrect');
?>

But the above code is obviously not rigorous enough, because in this way, even a mobile phone number like "18888888888" can pass the verification, so

We need to conduct more strict verification. Before going strict, please let us first take a look at the first three common mobile phone numbers in China

代码如下	复制代码
function checkMobile($str)      {          $pattern = “/^(13|15)d{9}$/”;          if (preg_match($pattern,$str))          {               Return true;          }          else          {              Return false;          }      }     //调用函数     $str = checkMobile(“15800000001″);      if($str)      {      echo(“符合手机号码标准”);      }      else      {      echo(“不符合手机号码标准”);      }     ?>

Some: Mobile phone numbers: 134, 135, 136, 137, 138, 139, 150, 151, 157 (TD), 158, 159, 187, 188 China Unicom mobile phone number: 130, 131, 132, 152, 155, 156, 185, 186 Telecom mobile phone numbers: 133, 153, 180, 189, (1349 Satcom) Then based on the above characteristics, we can modify the code to this rule:

The code is as follows

Copy code

Function checkMobile($str) {             $pattern = “/^(13|15)d{9}$/”; If (preg_match($pattern,$str))             {                Return true;          }         else             {               Return false;          } } //Call function $str = checkMobile(“15800000001″); If($str) { echo("Conforms to mobile phone number standards"); }       else { echo("Does not meet mobile phone number standards"); } ?>

The above can only start with 铓13,15. If there are new paragraphs, it will not work. We can modify them

function is_mobile($str){
Return preg_match("/^(((d{3}))|(d{3}-))?13d{9}$/", $str);
}  

The code is as follows

代码如下	复制代码
function is_mobile($str){       return preg_match("/^(((d{3}))|(d{3}-))?13d{9}$/", $str);       }

Copy code

This way all mobile phone numbers can be verified. http://www.bkjia.com/PHPjc/631504.htmlwww.bkjia.comtrue
