Question

http://sourceforge.net/projects/phpqrcode/, is a great library but i can’t find how to return the png image as a string, the basic examples are

QRcode::png('code data text', 'filename.png'); // creates file 
QRcode::png('some othertext 1234'); // creates code image and outputs it directly into browser

i checked the documentation and nothing, help! :B

Answer 1

ob_start();
QRCode::png('text', null);
$imageString = base64_encode( ob_get_contents() );
ob_end_clean();
