PHP foreach syntax

I am having trouble with the syntax of this code - I want to list several values such as name - email etc below the $Body. Do I have to list $Body several times to get the different values? Or can I concatenate the values with a <br>

foreach($_POST as $key => $value) {
                $Body .= "<p>$key: $value</p>";
            }

As written that code will assign the variable $Body with the POST request vars. After that, use echo to print $Body.

What do you want the code to do that it is not already doing?
The code as you have it will create a new line for each key value pair - what is it you are wanting?

I want to list the name, email, company name etc - I was thinking that I had to specify the email field name

The name field will be the $key variable.

I guess I am trying to figure out where to place the echo statement since I can't find an example with my format

Here's a self-contained example. You may find var_dump() to be very helpful!

<?php // demo/temp_johnmac328.php
/**
 * http://www.experts-exchange.com/questions/28937729/PHP-foreach-syntax.html
 */
error_reporting(E_ALL);

// IF THE FORM HAS BEEN POSTED
if (!empty($_POST))
{
    // SHOW THE CONTENTS OF THE REQUEST
    var_dump($_POST);

    // ITERATE OVER THE CONTENTS OF THE REQUEST
    $thing = NULL;
    foreach ($_POST as $key => $val)
    {
        $thing .= "<p>$key: $val</p>";
    }
    echo $thing;
}

// CREATE THE FORM USING HEREDOC NOTATION
$form = <<<EOD
<form method="post">
Name:  <input name="yourname" /><br>
Email: <input name="youremail" /><br>
Phone: <input name="yourphone" /><br>
<input type="submit" value="Go!" />
</form>
EOD;

echo $form;

Like this?

The mail server is not up yet

foreach($_POST as $key => $value) {
                $Body .= "<p>$key: $value</p>";
                echo $key['name'], " ", $$key['company_name'], " ", $$key['email'];
            }
