Escaping $ in HEREDOC string with PHP

Question

I have something like this

$var = <<<HEREDOC
..."request": ${"hello"}...
HEREDOC;

Of course PHP thinks ${"hello"} is a variable and it fails to load.

How to escape the $?

The PHP manual would have taught you right away: https://www.php.net/manual/en/language.types.string.php — AmigoJack, Jul 11 '19 at 14:41

The same way you escape almost anything in a string

$var = <<<HEREDOC
..."request": \${"hello"}...
HEREDOC;
echo $var;

RESULT

..."request": ${"hello"}...
