Pulling mySQL data and placing inside a variable in PHP - php

Question

I'm trying out something like below. I get to successfully display the $Message without the PHP script that you see in the middle.
$Message = "<table><tr><td>" <?php code A ?>"</td></tr></table>";
The "Code A" PHP script meant to pull some date from an SQL database and present inside a table as you would see.
I see with this code not working, the issue is the way I place the PHP script inside $Message.
Would like to know, first is this really possible to have a script running attempting to pull data from an mySQL database and assign the output to a variable and if so how should the script look like otherwise?
Here's the full code which represent Code A, if that helps in understanding the issue better.
<?php
if(!isset($_POST['savedata']))
{
echo 'some text message';
}
else
{
include ('dbconnect/index.php');
$SQLuserpw="SELECT * FROM USER WHERE EMAIL = '".htmlspecialchars($email)."'";
$user=mysqli_query($conn, $SQLuserpw) or die ('SQL Error');
$pendingRow=mysqli_num_rows($user);
if($pendingRow == '')
{ echo 'some text here';} else
{
while ($reK = mysqli_fetch_array($user))
{
$wec = $reK['FNAME']; $wec2 = $reK['LNAME']; $wec3 = $reK['EMAIL'];
echo '<table>';
echo '<tr><td>First Name</td><td> : </td><td>'.$reK['FNAME'].'</td></tr>';
echo '<tr><td>Last Name</td><td> : </td><td>'.$reK['LNAME'].'</td></tr>';
echo '<tr><td>Email</td><td> : </td><td>'.$reK['EMAIL'].'</td></tr>';
}
echo '</table>';
}
}
?>
UPDATE
Suggestion made by #ADyson works.

Answer 1

if the code piece you've shared is working, do it like that,
$message = '<table>';
$message .= '<tr><td>First Name</td><td> : </td><td>'.$reK['FNAME'].'</td></tr>';
$message .= '<tr><td>Last Name</td><td> : </td><td>'.$reK['LNAME'].'</td></tr>';
$message .= '<tr><td>Email</td><td> : </td><td>'.$reK['EMAIL'].'</td></tr>';
}
$message.= '</table>';
the use $message wherever you want.
