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?

You can use these instructions: Including External Files (http://www.vbulletin.com/docs/html/main/templates_externalfiles)
