PHP imagettftext() center text

Question

I want to center the text I add to my image using :

imagettftext($image, 85, 0, 250, 350, $color, $font, $txt );

I tried something like this :

$fontwidth1 = imagefontwidth($font);
$center1 = (imagesx($image)/2) - ($fontwidth1*(strlen($txt)/2));

However unfortunately it's not working. The imagefontwidth($font) part does not work :(

Anyone has faced this issue before and know an solution / alternative method ?

Can you be more specific than "does not work"? What happens and what do you expect to happen? — Jeffrey Bosboom, Dec 29 '14 at 01:14
(imagesx($image)/2) works gives correct value. ($fontwidth1*(strlen($txt)/2)) Returns 0. — BRDS, Dec 29 '14 at 01:15
I suggest using [imagettfbbox()](http://php.net/manual/en/function.imagettfbbox.php) — Austin Brunkhorst, Dec 29 '14 at 01:17

The function imagefontwidth works best with fixed-width fonts. Like Austin Brunkhorst said, the most reliable way to get centered text uses imagettfbbox, like so:

$bbox = imagettfbbox(85, 0, $font, $txt);
$center1 = (imagesx($image) / 2) - (($bbox[2] - $bbox[0]) / 2);
