Returning PHP values from functions.

[Mong]

I've not slept for days, so my brain is rotting. Anything wrong with this? I can't get $img back from the function...

function doImg ($title, $level, $img)
{

	if ($level == 4)
	{
		$img = $title.'-raog.gif';
	}
	elseif ($level == 3)
	{
		$img = $title.'-rao.gif';
	}
	elseif ($level == 2)
	{
		$img = $title.'-ra.gif';
	}
	else
	{
		$img = $title.'-r.gif';
	}
	return $img;

}

doImg('test', 1, $img);

echo '<img src=img/'.$img.'>';

Cheers,

M.

Either use

$img=doImg('test', 1, $img);

(preferred)


Or pass by reference to get the semantics you seem to want:

function doImg ($title, $level, &$img)

Goddamnitalltohell! Like I said, my brain is asleep today, I'm on auto.

Passing by reference in PHP is something I avoid wherever possible

Many thanks, my entirely pointless and self-indulgent thingie is working now

You think this is excessive? It uses a MySQL DB... surely that's entirely reasonable?

Though I suppose this sort of thing is common on blogs and IMs these days. Crazy kids.

I've never seen this kinda thing before... assumed I was being original

Well, "happy" or "unhappy" icons.

MySQL certainly isn't overkill. I can't think of a better protocol for transferring the data from your cybernetic implants to the web.

function doImg ( $title, $level )
{

	switch ( $level ) {
	case 4:
		$img = $title.'-raog.gif';
		break;
	case 3:
		$img = $title.'-rao.gif';
		break;
	case 2:
		$img = $title.'-ra.gif';
		break;
	default:
		$img = $title.'-r.gif';
	}

	return $img;

}

$img = doImg ( 'test', 1 );

echo '<img src="img/'.$img.'">';

Is probably better...
