How PHP converts image files into binary output,

The example in this article describes how PHP converts image files into binary output. Share it with everyone for your reference. The specific implementation method is as follows:

header( "Content-type: image/jpeg");
$PSize = filesize('1.jpg');
$picturedata = fread(fopen('1.jpg', "r"), $PSize);
echo $picturedata;

With just 4 lines of code, the image is output to the client in the form of a binary stream, which is no different from opening a picture.

It should be noted here that the header sent depends on the specific situation and may not always be image/jpeg. JPG is image/jpeg, but PNG is image/png. Different types of pictures output different headers.

I hope this article will be helpful to everyone’s PHP programming design.
