将HTML中的值添加到PHP中

我试图从HTML表单中获取提交的内容，并将其插入到作为操作的PHP文件中。下面提供的PHP代码是整个代码的一小部分，可在本页底部找到：

HTML表单

<form method="POST" action="/acform.php">

<div class="form-group"><input class="form-control" type="text" name="email" placeholder="email address"></div>
<div class="form-group"><input class="form-control" type="text" name="fname" placeholder="name"></div>
<div class="form-group"><input class="form-control" type="text" name="lname" placeholder="name"></div>
<div class="form-group"><input class="form-control" type="text" name="phone" placeholder="phone" inputmode="tel"></div>
<div class="form-group"><button class="btn btn-primary submit-btn" class="_submit" type="submit">Submit</button></div>

</form>

提交
//acform.php

为什么不直接使用

$\u POST

？在acform.php文件中，您应该有输出显示的内容？@jeff var\u dump output:Array（[email]=>test@gmail.com[fname]=>John[lname]=>Smith[phone]=>1234567890@JosephSible我试过了，但是输出是空的/空白的

$post = array(
    'email'                    => '**Need "email" value here**',
    'first_name'               => '**Need "fname" value here**',
    'last_name'                => '**Need "lname" value here**',
    'phone'                    => '**Need "phone" value here**',

<form method="POST" action="/acform.php">
<div class="form-group"><input class="form-control" type="text" name="email" placeholder="email address"></div>
<div class="form-group"><input class="form-control" type="text" name="fname" placeholder="name"></div>
<div class="form-group"><input class="form-control" type="text" name="lname" placeholder="name"></div>
<div class="form-group"><input class="form-control" type="text" name="phone" placeholder="phone" inputmode="tel"></div>
<div class="form-group"><button class="btn btn-primary submit-btn" name="submit" class="_submit" type="submit">Submit</button></div>

</form>

//acform.php
<?php
if(isset($_POST['submit'])){
$array = array(
    'email' => $_POST['email'],
    'first_name' => $_POST['fname'],
    'last_name' => $_POST['lname'],
    'phone' => $_POST['phone']
);

}

?>
