How to convert an image to Base64 encoding with PHP?

To convert an image to Base64 encoding with PHP, we can use the file_get_contents function.

For instance, we write

$path = 'myfolder/myimage.png';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);

to call pathinfo with the image $path to get the file extension of the image.

Then we call file_get_contents with the $path to return the content of the image.

Next, we build the $base64 string with

'data:image/' . $type . ';base64,' . base64_encode($data);

We put the .type after 'data:image/' and the base64 image that we get from base64_encode($data) at the end of the string.
