Question

我是一个php新手，知道有一个简单的解决方案，但我似乎无法找到它。我希望返回用户输入的符号字段并应用格式。

static function getFormatedNum($num){
    if(empty($num)){}else{
    $first=  "(".substr($num, 0, 3).")";
    $second= substr($num,3,3)."-";
    $third=substr($num,6,4);
    $num=$first.$second.$third;}
    return $num;

Answer 1

假设输入格式为：5555555555

function getFormattedNum($num)
{
    if($num){
        return "(" . substr($num,0,3) . ")"
            . substr($num,3,3) . "-"
            . substr($num,6);
    }
}

Answer 2

这并不能解释所有格式，有些电话号码可以放在不同的格式中，而且不能通过检查011或长度来完成。您需要一个完整的区域代码/组合列表，以检查每个可能的长度。

（+ 44）（0）20 7930 4832 +44 20 7930 4832 020 7930 4832

简单的解决方案可能是。此外，我对此代码不满意，我确定是否可以简化一千次。

private function cleanNumber($uglyNumber){

    $number = preg_replace("/[^0-9]/","",$uglyNumber);
    if(($check = substr($number,0,3))!=='011'){
        //NON 011 Numbers

        switch(strlen($number)){
            //Same Area Code 
            //123-4567
            case 7:
                $prefix = substr($number,0,3);
                $SLN = substr($number,3,10);
                $cleanNumber = $prefix.'-'.$SLN;
                break;

            //Domestic US
            //No International Number
            case 10:
            $area = substr($number,0,3);
            $prefix = substr($number,3,3);
            $SLN = substr($number,6,10);
            $cleanNumber = '('.$area.') ' .$prefix.'-'.$SLN;
                break;

            case 11:
            // International Number [1]
                $country = substr($number,0,1);
                $area = substr($number,0,3);

                break;

            case 13:

更新：在同一个功能中完成所有工作

function getFormatedNum($num){
    //first strip all the non-digit characters from the input
    $num = preg_replace("/[^0-9]+/", "", $num);
    //and only then re-format the phone-number   
    if(!empty($num)){
      $first=  "(".substr($num, 0, 3).")";
      $second= substr($num,3,3)."-";
      $third=substr($num,6,4);
      $num=$first.$second.$third;
    }
    return $num;
}
//test
echo getFormatedNum("408.807.9565");

<强>输出：

(408)807-9565
