PHP5 Tutorial: PHP's GD module generates barcodes

The version of PHP5 is used in this article. Note that the GD module of PHP should be turned on before use. gd.so for Php_gd2.dll,linux in Windows. Extract the compressed file to Apache and execute http://localhost/barcode/index.php. PHP5 generate barcodes See the following figure:

1. Type: Select barcode type

2. Output : picture format

3. Thickness: bar code Height

4. Resolution: Barcode Size

5. Font: bar code below the text size, you can not display text

6. Text: Barcode Printing Content

Of course, this PHP5 generated barcode program just to make the text into a barcode, but not flexible to use it embedded in other PHP programs, I will compress the inside of the test.php made some adjustments, so that it can be flexible for other programs. The runtime simply passes the barcode type and text to test.php, for example:

http://localhost/barcode/test.php?codebar=BCGcode39&text=20090729

or run http://localhost/barcode/mytest.php
