How to send an HTML email, what contains a php echo command? - php

Question

I searched for this everywhere, but I couldn't find it. I want to echo some variables. My message:
$mailMsg ='<table class="head-wrap" bgcolor="#999999" width: 100%; margin: 0; padding: 0;">
<tr margin: 0; padding: 0;">
<td margin: 0; padding: 0;"></td>
<td class="header container" align="" display: block !important; max-width: 600px !important; clear: both !important; margin: 0 auto; padding: 0;">
</td>
<td margin: 0; padding: 0;"></td>
</tr>
</table>
<table class="body-wrap" bgcolor="" width: 100%; margin: 0; padding: 0;">
<tr margin: 0; padding: 0;">
<td margin: 0; padding: 0;"></td>
<td class="container" align="" bgcolor="#FFFFFF" display: block !important; max-width: 600px !important; clear: both !important; margin: 0 auto; padding: 0;">
<div class="content" max-width: 600px; display: block; margin: 0 auto; padding: 15px;">
<table width: 100%; margin: 0; padding: 0;">
<tr margin: 0; padding: 0;">

Do not use + to connect strings in PHP. Use . instead.
And there is no need to echo the variable.
So instead of
' + echo $useremail + '
do
' . $useremail . '

You may also use placeholders in your HTML template and replace them with your vars then.
For example:
$mail_template = '<table><tr><td>##USERNAME##</td></tr></table>';
$mail_final = str_replace('##USERNAME##', $username, $mail_template);
// ...
mail($to, $subject, $mail_final, $headers);
