image create with gd lib, save output

[hyster]

this code works fine apart from it displays the image in the browser, what id like to happen is to have the image save to a folder, I don't understand all the code so I don't no what im looking for

<?php
$name = 'Hyster';


$img=imagecreatetruecolor(180,20);
imagealphablending($img,false);

$col=imagecolorallocatealpha($img,255,255,255,127);
imagefilledrectangle($img,0,0,180,20,$col);
imagealphablending($img,true);

$font=$_SERVER["DOCUMENT_ROOT"].'./Arial.ttf';
$color = imagecolorallocate($img, 0, 0, 0);
imagettftext($img,11,0,5,14,$color,$font,$name); 

header('Content-Type: image/png');
imagealphablending($img,false);
imagesavealpha($img,true);
imagepng($img);

exit;
?>

As per the manual, the second argument for imagepng() is a filename to save the image.

just come across another issue lol.

I cant use any html when using the code, I want to redirect after the code runs.

if I put the code into the php it still outputs as plain text not html

<meta http-equiv='refresh' content='5; url=./png.php?name=$nick' />
<?php
$name = $_GET['name'];

$img=imagecreatetruecolor(180,20);
imagealphablending($img,false);

$col=imagecolorallocatealpha($img,255,255,255,127);
imagefilledrectangle($img,0,0,180,20,$col);
imagealphablending($img,true);

$font=$_SERVER["DOCUMENT_ROOT"].'./Arial.ttf';
$color = imagecolorallocate($img, 0, 0, 0);
imagettftext($img,11,0,5,14,$color,$font,$name); 

header('Content-Type: image/png');
imagealphablending($img,false);
imagesavealpha($img,true);
imagepng($img, "./img/name/$name.png");
imagedestroy($img);
?>

header('Content-Type: image/png');

Because you're doing that. If you're not outputting the image then you can remove that line.

just encase any1 else has need for this , this is my final code to create a transparent png overlaid with text, rotate 90 deg and save to a folder

<?php

$nick = 'some source';

$img=imagecreatetruecolor(100,20);
imagealphablending($img,false);

$col=imagecolorallocatealpha($img,255,255,255,127);
imagefilledrectangle($img,0,0,180,20,$col);
imagealphablending($img,true);

$degrees = 90; //rotate image
$font=$_SERVER["DOCUMENT_ROOT"].'./Arial.ttf';
$color = imagecolorallocate($img, 0, 0, 0);
imagettftext($img,11,0,5,14,$color,$font,$nick); 

imagealphablending($img,false);
imagesavealpha($img,true);
$img1 = imagerotate($img, $degrees, 0);
imagepng($img1, "./img/name/$nick.png");
imagedestroy($img);

?>
