Interpolate a constant (not variable) into 'heredoc'
constants, heredoc, php, syntax
Solution
Use sprintf()
define('my_const', 100);
$string = <<< heredoc
<p>The value of my_const is %s.</p>
heredoc;
$string = sprintf($string, my_const);
Problem
Consider: ``` <?php define('my_const', 100); echo <<<MYECHO <p>The value of my_const is {my_const}.</p> MYECHO; ?> ``` If I put a variable inside the braces, it prints out. But not the constant. How can I do it?
