Imagestring
$image = imagecreatetruecolor(300, 50);
$color = imagecolorallocate($image, 999,999,999);
$textcolor = imagecolorallocate($image, 0, 0 ,0);
$font = 'travelerl.ttf';
imagefill($image, 0, 0, $color );
imagettftext ($image, 10 , 10, 0, 0, $textcolor , $font , 'hello' );
imagepng($image, 'captcha.png');
echo '<img src="captcha.png"/>';
Ps. ik heb de font al geupload en in de zelfde map gezet :).
Waarom doe je niet gewoon dit php script de data outputten? (Dus niet naar bestand schrijven. Moet sowieso haast wel met captcha enzo.)

weergeeft:
imagettftext ($image, 10 , 10, 0, 0, $textcolor , $font , 'hello' );
moet zijn:
imagettftext($image, 14, 0, 14, 30, $textcolor , $font , 'hello' );
