使用PHP更新多個字段（MySQL）

Question

我需要將數據庫（電話號碼）中的字段更新為新格式。 我可以使用mysqli來做到這一點，但是看到它貶值了，我想知道是否有人對使用mysqli更新多個字段有任何建議？ 數字格式化程序的數字代碼為：

function formatPhoneNumber($phoneNumber) {
    $phoneNumber = preg_replace('/[^0-9]/','',$phoneNumber);

    if(strlen($phoneNumber) > 10) {
        $countryCode = substr($phoneNumber, 0, strlen($phoneNumber)-10);
        $areaCode = substr($phoneNumber, -10, 3);
        $nextThree = substr($phoneNumber, -7, 3);
        $lastFour = substr($phoneNumber, -4, 4);

        $phoneNumber = '+'.$countryCode.' ('.$areaCode.') '.$nextThree.'-'.$lastFour;
    }
    else if(strlen($phoneNumber) == 10) {
        $areaCode = substr($phoneNumber, 0, 3);
        $nextThree = substr($phoneNumber, 3, 3);
        $lastFour = substr($phoneNumber, 6, 4);

        $phoneNumber = '('.$areaCode.') '.$nextThree.'-'.$lastFour;
    }
    else if(strlen($phoneNumber) == 7) {
        $nextThree = substr($phoneNumber, 0, 3);
        $lastFour = substr($phoneNumber, 3, 4);

        $phoneNumber = $nextThree.'-'.$lastFour;
    }

    return $phoneNumber;
}

查詢將是SELECT customers_id, customers_telephone FROM customers WHERE customers_telephone NOT IN (' ')那里，而SELECT customers_id, customers_telephone FROM customers WHERE customers_telephone NOT IN (' ') ，將影響近20,000行，最有效的方法是什么？

for循環看起來像這樣，但是它只是在做數組中的第一個客戶：

foreach($customers as $row)
{
    $customer_id = $row['customers_id'];
    $numbers_array = $row['customers_telephone'];
    function formatPhoneNumber($phoneNumber) {
    $phoneNumber = preg_replace('/[^0-9]/','',$phoneNumber);

    if(strlen($phoneNumber) > 10) {
        $countryCode = substr($phoneNumber, 0, strlen($phoneNumber)-10);
        $areaCode = substr($phoneNumber, -10, 3);
        $nextThree = substr($phoneNumber, -7, 3);
        $lastFour = substr($phoneNumber, -4, 4);

        $phoneNumber = '+'.$countryCode.'-'.$areaCode.'- '.$nextThree.'-'.$lastFour;
    }
    else if(strlen($phoneNumber) == 10) {
        $areaCode = substr($phoneNumber, 0, 3);
        $nextThree = substr($phoneNumber, 3, 3);
        $lastFour = substr($phoneNumber, 6, 4);

        $phoneNumber = $areaCode.'- '.$nextThree.'-'.$lastFour;
    }
    else if(strlen($phoneNumber) == 7) {
        $nextThree = substr($phoneNumber, 0, 3);
        $lastFour = substr($phoneNumber, 3, 4);

        $phoneNumber = $nextThree.'-'.$lastFour;
    }

    return $phoneNumber;
}
    formatPhoneNumber($numbers_array);
    echo $numbers_array."  -  ".$customer_id;

}

Answer 1

將函數移出循環。

然后更改最后兩行：

$formattedNumber = formatPhoneNumber($numbers_array);
echo $formattedNumber . "  -  " . $customer_id;
