PHP将图像从URL获取到字节数组并反转

Question

http://oep.esy.es/testimage.php as you can see here, that is the output of png image. image is here:

http://oep.esy.es/images/object/1365-50.png

My code is that:

$homepage = file_get_contents("http://oep.esy.es/images/object/1365-50.png");
echo $homepage;

I want to store as byte array because in Android client, I need that image so I need to pull it. Is it bad method?

But when I try to show image, it doesnot show:

echo "<img src='data:image/png;base64, $homepage' />";

I also tried jpeg but did not work.

You're missing the base64_encode() function, something like:

$path = file_get_contents("http://oep.esy.es/images/object/1365-50.png");
echo "<img src='data:image/png;base64, " . base64_encode($path) ."'/>";
