Usage

To install simply include:

• qrlib.php for full version (also you have to provide all library files form package plus cache dir)
• OR phpqrcode.php for merged version (only one file, but slower and less accurate code because disabled cache and quicker masking configured)

Then use it as follows:

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

Above examples show the most basic usage. For more features and customization see Detailed examples and PHP QR Code wiki or read INSTALL file in distrribution package.
