Outputting variable within Heredoc

Question

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

Make sure there are no trailing spaces on the line for EOF; – Reactgular Jan 16 '13 at 17:58 — Reactgular, Jan 16 '13 at 17:58

<?php

$email="test@example.com";

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

Some people (myself included) hate dropping in and out of PHP. – Evert Jan 16 '13 at 18:26
Why's that? That's part of the beauty of PHP. – showdev Jan 17 '13 at 18:26
Beauty is definitely in the eye of the beholder ;). All my templates are done using Twig, and all my PHP code follows PSR-0, and PSR-1. – Evert Jan 17 '13 at 19:21
I also make absolutely sure my PHP code doesn't contain any HTML ever, so I would personally also not be a fan of this particular heredoc block :P – Evert Jan 17 '13 at 19:21

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 = "bill@example.com";
$email2 = "ted@example.com";

$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/remove.php?email=bill@example.com">clicking here.</a></p>
<p>Click to remove <a href="http://www.mysite.com/remove.php?email=ted@example.com">clicking here.</a></p>
*/

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

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;
