I'm trying to figure out how to use a defined variable when using <<<HTML in php.
This is an example of what I want to achieve:
<?php
define('TEST','This is a test');
echo <<<HTML
Defined: {TEST}
HTML;
?>
What's the appropriate way of getting the defined "TEST" inside the <<<HTML ?
Edit:
I did a small test to check which one of the methods is the fastest.
For my test I used 20 variables inside heredoc. Here is what happened with the different methods (in seconds):
Accessing defined variable inside <<<HTML in php seems to be the slowest way of doing it - 0.00216103.
Accessing defined variable inside <<<HTML in php is faster - 0.00073290.
Accessing defined variable inside <<<HTML in php is even faster - 0.00052595.
Accessing defined variable inside <<<HTML in php is the fastest - 0.00011110.
Hope this helps somebody else :)

In order to get an input value, you can use the htmlspecialchars() method and $_REQUEST variable. Note: The htmlspecialchars() method functions by converting special characters to HTML entities. The $_REQUEST variable is a built-in PHP variable that functions by getting data from the input field.
It's not pretty I'm afraid, but ...
define('TEST','This is a test');
var $defined = TEST;
echo <<<HTML
Defined: {$defined}
HTML;
There isn't, so far as I'm aware at least, a way of using defined values directly in that context, you need to use a variable.

Here's a method I found in the notes on the php manual: http://www.php.net/manual/en/function.define.php#100449
It's a little convoluted, but it should work.
<?php
define('TEST','This is a test');
$cst = 'cst';
function cst($constant){
return $constant;
}
echo <<<HTML
Defined: {$cst(TEST)}
HTML;
If you have multiple defined CONSTANTS to include, this would be better than manually assigning lots of variables to the value of constants.
