简单的HTML / PHP表单需要永远发送电子邮件

Question

I have this simple email form using the POST function with a PHP mailto() function. I have PHP lines within my form as values to the fields. It takes way too long to send. Any help is appreciated.

PHP:

<?php

if ($_POST['submit']) {

    if (!$_POST['name']) {
        $error="<br/>-Please enter your name";
    }
        if (!$_POST['email']) {
        $error.="<br/>-Please enter your email";
    }
        if (!$_POST['message']) {
        $error.="<br/>-Please enter a message";
    }
        if (!$_POST['check']) {
        $error.="<br/>-Please confirm you're real";
    }

    if ($error){
        $result="Ohh no, somethings not right... $error";
    }
    else {

        mail("[e-mail]","website contact form","Name: ".$_POST['name']."
            Email: ".$_POST['email']."
            Message: ".$_POST['message']);

        {
            $result="Thank you, I will reply shortly.";
        }
    }
}
?>

HTML:

<form action="#contactme" method="post" role="form">
    <div class="form-group">
        <input type="text" name="name" placeholder="Enter your name" class="form-control form-control-lg" value="<? echo $_POST['name']; ?>" >
    </div>
    <div class="form-group">
        <input type="email" name="email" placeholder="Enter your email" class="form-control form-control-lg" value="<? echo $_POST['email']; ?>">
    </div>
    <div class="form-group">
        <textarea name="message" rows="5" class="form-control" placeholder="Your message..."><? echo $_POST['message']; ?> </textarea>
    </div>
    <div class="checkbox">
        <label>
            <input type="checkbox" name="check"><span class="real"> I am real</span>
        </label>
    </div>
    <div align="center">
        <input type="submit" name="submit" class="btn btn-secondary btn-lg" value="Send">
    </div>
</form>

I have done everything in a query now it should be sent faster but it can also be that this code has an error but the first query is correct from the structure.

<?php

if ($_POST['submit']) {

    if (!$_POST['name'] || !$_POST['email'] || !$_POST['message'] || !$_POST['check'] ||) {
        $error="<br/>-Please enter";
    }else
{

 if ($error){
        $result="Ohh no, somethings not right... $error";
    }
    else {

        mail("[e-mail]","website contact form","Name: ".$_POST['name']."
            Email: ".$_POST['email']."
            Message: ".$_POST['message']);

        {
            $result="Thank you, I will reply shortly.";
        }
    } <-- If you have a mistake, take a clip away.


}


}
