How to convert an image to base64 encoding?

Question

Can you please guide me how can I convert an image from a URL to base64 encoding?

Answer 1

Very simple and to be commonly used:

function getDataURI($imagePath) {
    $finfo = new finfo(FILEINFO_MIME_TYPE);
    $type = $finfo->file($imagePath);
    return 'data:'.$type.';base64,'.base64_encode(file_get_contents($imagePath));
}

//Use the above function like below:
echo '';
echo '';

Note: The Mime-Type of the file will be added automatically (taking help from this PHP documentation).
