Question

我需要将数据库中的字段（电话号码）更新为新格式。我可以用mysql做到这一点，但看到它的折旧我想知道是否有人有任何使用mysqli更新多个字段的提示？数字格式器的数字代码是：

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;
}

查询将是SELECT customers_id, customers_telephone FROM customers WHERE customers_telephone NOT IN (' ')，会有近20,000行受影响，最有效的方法是什么？

for循环看起来像这样，但它只是在数组中做第一个客户：

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;

}

将你的功能移出你的循环。

然后改变最后两行：

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

使用PHP更新多个字段（MySQL）
