The PHP5 instance tutorial is simple to generate a barcode

This document uses the PHP5 version. Before using the function, you must enable the GD module of PHP. In Windows, it is php_gd2.dll, and in Linux it is gd. so. This document uses the PHP5 version. Before using the function, you must enable the GD module of PHP. In Windows, it is php_gd2.dll, and in Linux it is gd. so. Decompress the compressed file to Apache and execute http: // localhost/barcode/index. php. For more information about generating the PHP5 barcode, see:

1.Type:Select the barcode type

2.Output:Output Image format

3.Thickness:Bar code height

4.Resolution:Barcode size

5.Font:The text size below the bar code is not displayed

6. Text: bar code printed content

Of course, this PHP5 generated barcode program only generates text as a barcode, but it cannot be flexibly embedded into other PHP programs during use. I will compress the test in the package. php has made some adjustments so that it can be used flexibly in other programs. You only need to pass the barcode type and text to test. php at runtime, for example:

Http: // localhost/barcode/test. php? Codebar = BCGcode39 & text = 20090729

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

Mytest. php code:
