验证在PHP形式的手机号码(Validate Mobile number in php form)

我想验证的10位手机号码，并添加0前缀当我输入到数据库中。

<?php

include ('database_connection.php');

$citystate = $_POST['citystate'];
$serviceprovider = $_POST['serviceprovider'];
$accept = $_POST['accept'];
if (isset($_POST['formsubmitted'])) {
    $error = array(); //Declare An Array to store any error message 

    if (isset($_POST['checkbox'])) {
        $mumbai = (in_array("mumbai", $_POST['checkbox']) ? 1 : 0);
        $pune = (in_array("pune", $_POST['checkbox']) ? 1 : 0);
        $banglore = (in_array("banglore", $_POST['checkbox']) ? 1 : 0);
        $mysore = (in_array("mysore", $_POST['checkbox']) ? 1 : 0);
    }

    if ($mumbai + $pune + $banglore + $mysore == 0) {
        $error[] = 'Please check atleast one SMS center';
    }

    if ($accept != 1) {
        $error[] = 'Please check terms ';
    }

    if (empty($_POST['mobileno'])) {//if no name has been supplied 
        $error[] = 'Please Enter a Mobile Number '; //add to array "error"
    }
    if (empty($_POST['mobileno'])) {//if no name has been supplied 
        $error[] = 'Please Enter a Mobile Number '; //add to array "error"
    } else {

        $mobile = $_POST['mobileno']; //else assign it a variable

        /* if( preg_match("^[0-9]{10}", $mobile) ){

          }

          else {

          $error[] = 'Your Mobile No is invalid  ';
          } */
    }
    if (empty($_POST['fname'])) {//if no name has been supplied 
        $error[] = 'Please Enter a First name '; //add to array "error"
    } else {
        $fname = $_POST['fname']; //else assign it a variable
    }

    if (empty($_POST['lname'])) {//if no name has been supplied 
        $error[] = 'Please Enter a Last name '; //add to array "error"
    } else {
        $lname = $_POST['lname']; //else assign it a variable
    }
    if (empty($_POST['email'])) {
        $error[] = 'Please Enter your Email ';
    } else {
        if (preg_match("/^([a-zA-Z0-9])+([a-zA-Z0-9\._-])*@([a-zA-Z0-9_-])+([a-zA-Z0-9\._-]+)+$/", $_POST['email'])) {
            //regular expression for email validation
            $email = $_POST['email'];
        } else {
            $error[] = 'Your EMail Address is invalid  ';
        }
    }


    if (empty($_POST['passwd1'])) {
        $error[] = 'Please Enter Your Password ';
    } else {
        $password = $_POST['passwd1'];
    }
    if (empty($_POST['passwd2'])) {
        $error[] = 'Please Verify Your Password ';
    } else {
        $password = $_POST['passwd2'];
    }
    if ($_POST["passwd1"] != $_POST["passwd2"]) {
        $error[] = 'Password does not match';
    }

    if (empty($error)) { //send to Database if there's no error ' //If everything's OK...
        // Make sure the mobile no is available:
        $query_verify_mobileno = "SELECT * FROM userdtls WHERE mobileno = '$mobile'";
        $result_verify_mobileno = mysqli_query($dbc, $query_verify_mobileno);
        if (!$result_verify_mobileno) {//if the Query Failed ,similar to if($result_verify_mobileno==false)
            echo ' Database Error Occured ';
        }

        if (mysqli_num_rows($result_verify_mobileno) == 0) { // IF no previous user is using this number .
            // Create a unique  activation code:
            //$activation = md5(uniqid(rand(), true));
            $query_insert_user = "INSERT INTO userdtls ( mobileno, serviceprovider, pass,  fname, lname, email, citystate, MUM, PUN, BNG, MYS ) VALUES ( '" . $mobile . "', '" . $serviceprovider . "', '" . $password . "', '" . $fname . "', '" . $lname . "', '" . $email . "', '" . $citystate . "','" . $mumbai . "', '" . $pune . "', '" . $banglore . "', '" . $mysore . "'  )";
        }
    }
}

现在，我陷在手机号码验证。我尝试使用正则表达式。

我想要做的就是添加一个10位数的电话号码，并确保它仅仅是个数字，否则给予错误，而输入号码数据库我想添加一个前缀为0的手机号码，以便它应该像0and10digitnumber

Answer 1:

尝试是这样的：

$phoneNumber = $_POST['mobileno'];

if(!empty($phoneNumber)) // phone number is not empty
{
    if(preg_match('/^\d{10}$/',$phoneNumber)) // phone number is valid
    {
      $phoneNumber = '0' . $phoneNumber;

      // your other code here
    }
    else // phone number is not valid
    {
      echo 'Phone number invalid !';
    }
}
else // phone number is empty
{
  echo 'You must provid a phone number !';
}

Answer 2:

或许最为有效和良好可读的形式将来自谷歌使用libphonenumber库。 PHP叉可以在GitHub上。它可以帮助你不仅要验证数字本身，但你可以检查国家代码与它甚至不知道，如果一些号码有效期为特定国家 （这LIB知道哪些号码前缀是有效的许多国家）。例如： 07700 900064是有效的GB数，但09700 900064不大，即使他们有相同的长度 。

这是我怎么会在验证您的应用程序的手机号码：

$phoneNumber = $_POST['mobileno'];
$countryCode="GB";

if (!empty($phoneNumber)) { // phone number is not empty
    $phoneUtil = \libphonenumber\PhoneNumberUtil::getInstance();
    $mobileNumberProto = $phoneUtil->parse($phoneNumber, $countryCode);
    if ($phoneUtil->isValidNumber($mobileNumberProto)) { // phone number is valid
        //here you know that number is valid, let's try to format it without country code but with 0 at the beginning (national number format)
        $phoneNumber = $mobileNumberProto->format($mobileNumberProto, PhoneNumberFormat::NATIONAL);
    } else {
        $error[] = 'Phone number not valid!';
    }
} else {
    $error[] = 'You must provide a phone number!';
}

$countryCode在两个字符ISO 3166-1代码。您可以检查它在你的国家维基百科。

Answer 3:

你有没有试过像一个正则表达式：

if( !preg_match("/^([0-1]-)?[0-9]{3}-[0-9]{3}-[0-9]{4}$/i", $phone) ) {
   echo 'Please enter a valid phone number';
}

Answer 4:

对于印度的手机号码将是最简单

if(is_numeric($num)){
if($num=>1000000000 and $num=<9999999999){
$num="0".$num;
}
else{
echo "Invalid Mobile Number";
}
}
else{
echo "Hey Buddy mobile numbers are always in digits";
}

这种想法打我，因为很容易找到一些短期心态的意愿，因为号码（1000000000）是最低的数值（10位）和数量（9999999999）是可用于在印度的手机号码最高数值。还有一个件事代码将运行比其他解决方案快多了。

Answer 5:

if(!ereg("^[7-9]{1}[0-9]{9}$", $mob)) { return false; }

Answer 6:

提高普拉温帕蒂的回答：

if(!ereg("^[7-9]{1}[0-9]{9}$", $mob)) { return false; }

因为额日格（）已被弃用，你可以使用

preg_match("/^[7-9]{1}[0-9]{9}$/i", $mobile_no)

这将帮助你从印度验证手机号码，因为他们是10位，并与7，8或9今天开始。你总是可以改变的格局是否有新数字得到介绍。
