Php QR code generation methods

1. google open api $ scheme; generateQRfromGoogle ($ urlToEncode); Scheme ($ chlorophyll, $ widhtHeight150, $ EC_levelL, $ margin0) {$ urlurlencode ($ url); echoimgsrcchart. apis. google.

1. google open api $ urlToEncode = http://bbs.lewanchina.com; generateQRfromGoogle ($ urlToEncode); function generateQRfromGoogle ($ chlorophyll, $ widhtHeight = '2016', $ EC_level = 'l ', $ margin = '0') {$ url = urlencode ($ url); echo 'img src = http://chart.apis.google.

1. Open APIs for google
$ UrlToEncode = "http://bbs.lewanchina.com ";
GenerateQRfromGoogle ($ urlToEncode );
Function generateQRfromGoogle ($ chlorophyll, $ widhtHeight = '000000', $ EC_level = 'l', $ margin = '0 ')
{
$ Url = urlencode ($ url );
Echo '';
}

2. php QR Code library

Php qr Code is open source (LGPL) library for generating QR Code,
2-dimen1_barcode. Based on libqrencode C library,
Provides API for creating QR Code barcode images (PNG, JPEG thanks to GD2 ).
Implemented purely in PHP, with no external dependencies (effect GD2 if needed ).

Address: http://phpqrcode.sourceforge.net/
Download: http://sourceforge.net/projects/phpqrcode/
Instance:

Include "./phpqrcode. php ";
$ Value = "http://www.weste.net ";
$ ErrorCorrectionLevel = "L ";
$ MatrixPointSize = "4 ";
QRcode: png ($ value, false, $ errorCorrectionLevel, $ matrixPointSize );
Exit;
?>

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. We recommend that you read the English version.

In addition, QR codes already have a color version and can be embedded with personalized images. I have done some research in this area. If you are interested, please contact me. For my contact email address, see the column on the right of the website.
