為什么我的簡單郵件php表單需要很長時間才能加載？

Question

下午好，堆棧！ 我目前正在處理一個簡單的PHP郵件表單，而在開始編輯之前，我的上一個版本實際上花了不到一秒鍾的時間來實際加載表單，但是現在有了這些新功能，現在至少需要5到10秒鍾才能加載該表單。 。

這是我當前的代碼，現在加載需要很長時間，這是一個實時鏈接 ；

<?php
// We use the name2 field as bait for spambots.  It's display is off,
// so humans wouldn't know to enter anything into it.  Robots would, 
//  so we ignore submissions with info in name2.

$mail_sent = false;

if(sizeof($_POST) && $_POST["name2"] == "") // receiving a submission
{   

 // receiving a submission
    $to = $_POST['department'];

    // prep our data from the form info
    $senderName     = $_POST['name'];
    $senderEmail    = $_POST['email'];
    $department     = $_POST['department'];
    $subject        = "Visitor message in $department department"; 
    $messageBody    = $senderName . ' ('.$senderEmail.') wrote for '.$department.' department: ' . $_POST['message'];

    if($department == 'customer') { //if customer was selected
    $to = 'email@email.com';
    }

    else if($department == 'distribution') { //if distribution was selected
    $to = 'email@email.com, email@email.com';
    }

    else if($department == 'press') { //if press was selected
    $to = 'email@email.com';
    }

    else if($department == 'career') { //if career was selected
    $to = 'email@email.com';
    }

    else if($department == 'other') { //if other was selected
    $to = 'email@email.com';
    }

    // From 
    $header = "From: $senderName <$senderEmail>";
}

    // Send it!

    $send_contact = mail($to, $subject, $messageBody, $header);

    if($send_contact){
        $mail_sent = true;
    }
    else {
        echo " ";
    }
?>

我確實發現了一件奇怪的事情，盡管將其更改發送給多個接收者，但開始告訴我錯誤，盡管它工作得很好，所以我進行了更改。

if($send_contact){
    $mail_sent = true;
}
else {
    echo "ERROR";
}

只能打印空格，因此用戶看不到它。也許，這是什么原因導致實際上正在進行某事，從而延長了加載延遲？ 但是..它的工作原理很棒，也很好。

任何人都知道為什么此表格可能需要這么長時間才能加載？ 絕對是我刪除或恢復到舊版本時的代碼，使用ySlow加載不到一秒鍾。

這是我的代碼的上一個版本，可立即加載並帶有實時鏈接 ；

<?php

// We use the name2 field as bait for spambots.  It's display is off,
// so humans wouldn't know to enter anything into it.  Robots would, 
//  so we ignore submissions with info in name2.

$mail_sent = false;

if(sizeof($_POST) && $_POST["name2"] == "") // receiving a submission
{   
    define("SUBJECT",   "Visitor Message from Domain.com");

    // production recipient:
    define("RECIPIENT", "email@email.com");

    // prep our data from the form info
    $senderName     = $_POST['name'];
    $senderEmail    = $_POST['email'];
    $subject        = SUBJECT; 
    $messageBody    = $senderName . ' ('.$senderEmail.') wrote:

' . $_POST['message'];

    // From 
    $header         = "from: $senderName <$senderEmail>";

    // To
    $to = RECIPIENT;

    // Send it!
    $send_contact = mail($to, $subject, $messageBody, $header);

    // Check success of send attempt
    if($send_contact){
        // show thankyou screen
        $mail_sent = true;
    }
    else {
        // send failed.
        echo "ERROR";
    }
}

?>

感謝您的幫助，因為我已經堅持了一段時間，感謝您的時間和精力，祝大家周末愉快。

$send_contact = mail($to, $subject, $messageBody, $header);

if($send_contact){
    $mail_sent = true;
}
else {
    echo " ";
}

這部分代碼未包含在處理新版本中的表單提交的if塊中。 因此，它在頁面每次加載時都會執行。 這將減慢加載速度，因為mail（）函數嘗試發送電子郵件並在每次加載頁面時給出錯誤。 您的意圖是僅在正確提交表單后才發送電子郵件。 從那以后，打開php通知將是一個好主意。 這樣可以更輕松地捕獲此類錯誤。
