Question

我制作了一个联系表，用于从观众那里收集信息，除了电话号码格式外，它都正常工作，输入的内容似乎都没有格式。我不知道怎么了。

例如，如果我在表单中输入123 555 7890，它将返回为“ 1235557890”，而不是（123）555-7890。

<?php
error_reporting(0);
$msg = "";

if (isset($_POST['submit'])) {
    $to = "my_email";
    $subject = "Contact Form";
    $name = stripcslashes($_POST['name']);
    $email = stripcslashes($_POST['email']);
    $tel = stripcslashes($_POST['tel']);
    $message = stripcslashes($_POST['message']);

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

        if (strlen($tel) > 10) {
            $countryCode = substr($tel, 0, strlen($tel) - 10);
            $areaCode = substr($tel, -10, 3);
            $prefix = substr($tel, -7, 3);
            $lineNumber = substr($tel, -4, 4);

            $tel = '+' . $countryCode . '(' . $areaCode . ') ' . $prefix . '-' . $lineNumber;
            echo $tel;
        } elseif (strlen($tel == 10)) {
            $areaCode = substr($tel, 0, 3);
            $prefix = substr($tel, 3, 3);
            $lineNumber = substr($tel, 6, 4);

            $tel = '(' . $areaCode . ') ' . $prefix . '-' . $lineNumber;
            echo $tel;
        } elseif (stat($tel) == 7) {
            $prefix = substr($tel, 0, 3);
            $lineNumber = substr($tel, 3, 4);

            $tel = $prefix . '-' . $lineNumber;
            echo $tel;
        }

        return $tel;
    }

    $msgBody = 'Name: ' . $name . "<br>" . 'Email:' . $email . "<br>" . 'Phone Number: ' . formatTelNumaber($tel) . "<br>" . 'Message: ' . "<br>" . $message;
    $headers = 'From: ' . $email;

    if (mail($to, $subject, $msgBody, $headers)) {
        $msg = "Message Sent Successfully!";
    } else {
        $msg = "Message Not Sent! Please Try Again";
    }
}
?>

Answer 1

此行是错误的：

       } elseif (strlen($tel == 10)) {

== 10应该在函数调用之外：

       } elseif (strlen($tel) == 10) {

和

        } elseif (stat($tel) == 7) {

应该呼叫strlen()，而不是stat()； stat()要求$tel是文件名，它返回有关文件的信息数组。

函数无法正确格式化数字
