fix The image .. cannot be displayed, because it contains errors.

<?php
header("Content-type: image/png");
$im = @imagecreate(110, 20)
or die("Cannot Initialize new GD image stream");
$background_color = imagecolorallocate($im, 0, 0, 0);
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5,  "A Simple Text String", $text_color);
imagepng($im);
imagedestroy($im);
?>

you get error The image “http://localhost/ip/image.php” cannot be displayed, because it contains errors.

do bạn save as file dạng utf-8

chuyển về ansi có thể chạy được( now  save it as ANSI and it works as expected )
