Display image in PHP (Laravel)
提问by Alex
I'm trying to display a png image in PHP (Laravel)
我正在尝试在 PHP (Laravel) 中显示一个 png 图像
So far I've tried
到目前为止我已经尝试过
$response = Response::make(readfile(public_path() .
"/img/$image_name.png", 200))->header('Content-Type', 'image/png');
return $response;
and this
和这个
$file = public_path() . "/img/$image_name.png";
$im = imagecreatefrompng($file);
header('Content-Type: image/png');
imagePNG($im);
imagedestroy($im);
I always get something like this instead of an actual image
我总是得到这样的东西而不是实际图像
?PNG IHDR:?c PLTE????>tRNS?* ?< pHYs???+uIDAT(?e?? AJs *?[P???@8???Y?:????s?A?"D?!B?"D?!B?"D?!C~????}??Q??N?+'??bP?.a&^O)%5Y\?L????.?9??IEND?B`?
When I use jpeg header and jpeg image it starts showing the actual image in browser, but for some reason it doesn't work for png images. Have anyone faced a similar problem?
当我使用 jpeg 标题和 jpeg 图像时，它开始在浏览器中显示实际图像，但由于某种原因它不适用于 png 图像。有没有人遇到过类似的问题？

You should find the mime dynamicaly using laravel default file facade File::mimeType($path)because as you mentioned that it is working fine with another image type like jpeg. I think this may happen because sometime we change file extension for testing or may be file have some issue with its header etc. You can use the following code :
您应该使用 Laravel 默认文件外观动态地找到 mime，File::mimeType($path)因为正如您所提到的，它可以与 jpeg 等其他图像类型一起正常工作。我认为这可能是因为有时我们更改文件扩展名以进行测试，或者文件的标题等可能存在问题。您可以使用以下代码：
Method 1 use Response::stream:
方法一使用Response::stream：
$path = public_path() . "/img/$image_name.png";
$file = File::get($path);
$type = File::mimeType($path);
$response = Response::stream(function() use($file) {
echo $file;
}, 200, ["Content-Type"=> $type]);
Method 2 use Response::make:
方法二使用Response::make：
$path = public_path() . "/img/$image_name.png";
$file = File::get($path);
$type = File::mimeType($path);
$response = Response::make($file, 200);
$response->header("Content-Type", $type);
return $response;
Hope it will help.
希望它会有所帮助。
