PHP在服务器上显示来自PNG源的JPG图像？

我的服务器上是否可能有png图像，但是有一个php脚本将其转换为jpg（并压缩它们）并在查看时将其缓存？

Answer 1

You can use this script for convert PNG image into JPEG image.

$input_file = "test.png";

$input = imagecreatefrompng($input_file);
list($width, $height) = getimagesize($input_file);
$output = imagecreatetruecolor($width, $height);
imagecopy($output, $input, 0, 0, 0, 0, $width, $height);
