is it possible to directly call a function within a heredoc string.

i know we can use a local variable to store the function result and then use it in heredoc

is there a better way to do or any alternatives?

"Note: Functions, method calls, static class variables, and class constants inside {$} work since PHP 5. However, the value accessed will be interpreted as the name of a variable in the scope in which the string is defined. Using single curly braces ({}) will not work for accessing the return values of functions or methods or the values of class constants or static class variables. "

http://php.net/manual/en/language.types.string.php

You are best doing it the way you currently are.

<?php

function getName(){
	return "Timmy";
}

$Timmy = "Bob";

echo "My Name is: {${getName()}}";

?>



<?php
$beer = 'Heineken';

echo "He drank some {$beer}s";

?>

Yes, do it that way.  The more levels of "compound code" you create, the more certain you can be that disaster is not left to chance.  I am a BIG FAN of writing the simplest, clearest code (you already knew that, right?)

Best, ~Ray
