Last Updated on 20 November 2017 By tommy Leave a Comment

Contoh script

 
<?php
// Create a 100*30 image
$im = imagecreate(100, 30);
 
// White background and blue text
$bg = imagecolorallocate($im, 255, 255, 255);
$textcolor = imagecolorallocate($im, 0, 0, 255);
 
// Write the string at the top left
imagestring($im, 5, 0, 0, 'Hello world!', $textcolor);
 
// Output the image
header('Content-type: image/png');
 
imagepng($im);
imagedestroy($im);
?>

script diambil dari php imagestring, solusinya hapus spase kosong di baris pertama, hingga menjadi

<?php
// Create a 100*30 image
$im = imagecreate(100, 30);
 
// White background and blue text
$bg = imagecolorallocate($im, 255, 255, 255);
$textcolor = imagecolorallocate($im, 0, 0, 255);
 
// Write the string at the top left
imagestring($im, 5, 0, 0, 'Hello world!', $textcolor);
 
// Output the image
header('Content-type: image/png');
 
imagepng($im);
imagedestroy($im);
?>
