call a function

hello,
is it possible to call a function depending on a variable value? and how?

example:

$f_name = "abc";

$f_name();  // <--I wanna call abc() here, how to do it?

PHP:

thanks!

 

That is how you do it. You did it exactly right

 

You may want to verify it with is_callable before actually attempting to call it.

 

<?php
function testme(){ echo 'test';}
$myfunction = 'testme';
${myfunction}();
?>

PHP:

Peace,

 

you don't really need the curly brackets, though
