Could someone please advise why?

In this article, we will discuss how to convert a raw image to a binary image in PHP.

First of all, we will discuss what exactly a binary image is.

What is a binary image?

A binary image is a 64bit encoded binary data that takes 33% more data than the original image. It is basically applied to images with less size for faster loading of the image.

How to convert to a binary image in PHP

Note:-

• In the above script, file_get_contents[] method load an image from a path.
•  file_get_contents[] method can also load an image from a link.

Example of Image from a path is as follows,

$image_path=file_get_contents['D:/PICS/Pexels/photo-814194.jpeg'];

In this way, we can convert an image to binary from raw image using PHP. If you have any doubts about this article, leave a comment below.
