Outputting variable within Heredoc

I have some html spanning over EOF:

$message = <<<EOF

<p style="font-size: 9px; font-family: Verdana, Helvetica; width: 100%; text-align:left;">Clcik to remove <a href="http://www.mysite.com/remove.php?email=' $email '">clicking here.</a></p>

EOF;

I've tried single quotes, single quotes with . escaping the double quotes. Can't seem to find the right combination. Any help appreciated.

TIA

Heredoc is typically used for longer strings, or maybe even multiple thoughts, that you may want segmented on to separate lines.

As tuxradar put it: "In order to allow people to easily write large amounts of text from within PHP, but without the need to constantly escape things, heredoc syntax was developed"

<?php
$mystring = <<<EOT
    This is some PHP text.
    It is completely free
    I can use "double quotes"
    and 'single quotes',
    plus $variables too, which will
    be properly converted to their values,
    you can even type EOT, as long as it
    is not alone on a line, like this:
EOT;
?>

In your case, it'd make more sense to simply echo out your string.

$message = '<p style="font-size: 9px; font-family: Verdana, Helvetica; width: 100%; text-align:left;">Clcik to remove <a href="http://www.mysite.com/remove.php?email=' $email '">clicking here.</a></p>';

echo $message;

Your code should work, but with Heredocs [which is what this syntax is actually called] you don't usually need to escape anything, or use specific quotes. @showdev's first example hits this.

However, a cleaner, more reusable syntax is found with sprintf().

$email1 = "[email protected]";
$email2 = "[email protected]";

$message_frame = '<p>Click to remove <a href="http://www.mysite.com/remove.php?email=%s">clicking here.</a></p>';

$message .= sprintf($message_frame, $email1);
$message .= sprintf($message_frame, $email2);

/* Output:
<p>Click to remove <a href="http://www.mysite.com/[email protected]">clicking here.</a></p>
<p>Click to remove <a href="http://www.mysite.com/[email protected]">clicking here.</a></p>
*/

Lastly: large, inline style="" declarations really defeat the purpose of CSS.

<?php

$email="[email protected]";

$message = <<<EOF
<p style="font-size: 9px; font-family: Verdana, Helvetica; width: 100%; text-align:left;">Click to remove <a href="http://www.mysite.com/remove.php?email=$email">clicking here.</a></p>
EOF;

echo $message;

?>

However, from your example, I don't see the purpose of HEREDOC. Why not just:

<p style="font-size: 9px; font-family: Verdana, Helvetica; width: 100%; text-align:left;">Click to remove <a href="http://www.mysite.com/remove.php?email=<?=$email?>">clicking here.</a></p>
