在PHP中的手機號碼添加前綴，將它發送到數據庫

Question

可能重複之前：
Please help me VALIDATE Mobile no in php form

我的手機號碼來驗證，但我被困在前綴部分。

if(empty($_POST['mobileno'])) // phone number is not empty 
{ 
$error[] = 'Please enter mobile number'; 
} else { 
if(preg_match('/^\d{10}$/',$_POST['mobileno'])) // phone number is valid 
{ 
    $mobile = $_POST['mobileno']; 
    // your other code here 
} 
else // phone number is not valid 
{ 
    $error[] = 'Phone number invalid !'; 
} 
} 
$prefix = 0; 
$pmobile = $prefix . $mobile; 

這就是我想要做的前綴。這是正確的，因爲我不能在數字前加0。

您是否嘗試過使用正則表達式？

//check the first section is singular or multi, check area code between 0 and 9, check any additional integers 
$pattern = "[0|00]+[0-9]+[^\\s]"; 
$phone_number = "000263712702879"; //international phone number 
if(preg_match($pattern, $phone_number)) { 
     echo "this is a number"; 
} else echo "this not a number";
