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

Just in case you are (for whatever reason) unable to use curl nor file_get_contents, you can work around:

$img = imagecreatefrompng('...');
ob_start();
imagepng($img);
$bin = ob_get_clean();
$b64 = base64_encode($bin);
