How can I include functions that return echo values to my styles?

[ThorstenA]

There are functions that return echo values, how can I integrate them with style where I have a $content variable?

function sayhello()
{
	echo 'hello';

}

I tried this but it did not work.

eval('$content .= "' .  sayhello() .  '";');

$content .=  sayhello();

You would need to use a return() instead of echo.

Unfortunately functions I need from adminfunctions.php and adminfunctions_stats.php only return echo values. Is there a way to handle these echo values like returns?
