Use googleapi to generate a QR code business card example _ PHP Tutorial

Use googleapi to generate a QR code business card example. Two-dimensional barcode can be divided into stacked two-dimensional barcode and matrix two-dimensional barcode. Stacked two-dimensional bar codes are stacked by one-dimensional code blocks with multiple lines. The two-dimensional bar codes of moment and two-dimensional codes of moment can be divided into two-dimensional stacked/row-arranged barcode and two-dimensional matrix barcode. Stacked/row-lined two-dimensional bar codes are stacked by one-dimensional bar codes with multiple lines of short cut; matrix two-dimensional bar codes are composed of matrices, in the corresponding element position of the matrix, "point" indicates the binary "1", and "null" indicates the binary "0", "point" and "null" to form the code.

Stacked/row-based two-dimensional bar codes, such as Code 16 K, Code 49, and Code 417.

Matrix qr code is the most popular one.

The matrix QR code stores a larger amount of data. it can contain numbers, characters, Chinese text, and other mixed content. it has a certain degree of fault tolerance (it can be read normally after some damages). It has a high space utilization rate.

The code is as follows:
$ Vname = 'test '; $ Vtel = '000000 '; GenerateQRfromGoogle ($ vname, $ vtel ); Function generateQRfromGoogle ($ vname, $ vtel, $ widhtHeight = '000000', $ EC_level = 'l', $ margin = '0 ') { If ($ vname & $ vtel ){ $ Chlorophyll = "BEGIN: VCARDnVERSION: 3.0". // vcard header information "NFN: $ vname ". "NTEL: $ vtel ". "NEND: VCARD"; // vcard tail information Echo ''; } } ?>

Php generates the url qr code:

The code is as follows:
$ Url = "http://www.google.com.hk "; GenerateQRfromGoogle ($ url ); Function generateQRfromGoogle ($ chlorophyll, $ widhtHeight = '000000', $ EC_level = 'l', $ margin = '0 ') { Echo ''; } ?>

The code is as follows:

If you want to achieve the effect of a logo in the middle, you need to splice it with another logo thumbnail. Only one implementation method is provided here, and it can also be generated through QRcode.

For standard vcode information, see Wikipedia.

Note: Some generated images do not have scanned data because of encoding. this problem is common in windows. many editors provide ANSI encoding by default, change to utf8 and then OK.
