QR code

Data indicates the Data to be recorded. a maximum of 984 UTF-8 encoded Chinese characters can be stored.
ECC indicates the error correction level. the higher the error correction level, the larger the image to be generated.

L horizontal code 7% can be corrected M horizontal code 15% can be corrected Q horizontal code 25% can be corrected H horizontal code 30% can be corrected

Size indicates the pixels of each black spot in the image.

Code call example:

Include "qrlib. php "; QRcode: png ($ data, $ filename, $ errorCorrectionLevel, $ matrixPointSize, $ margin ); /* $ data $ name of the image saved by filename $ errorCorrectionLevel error handling level $ matrixPointSize pixels of each black spot $ white border pixels outside the margin image */

For details about the QR code, refer to the QR Wikipedia. the Chinese version is rarely described. The English version is very comprehensive.
