Simple Example of generating a barcode in PHP5

This software supports two versions: PHP4 and PHP5. The PHP5 version is used in this article. 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 executeHttp: // 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: bar code size

5. Font: the text at the bottom of the bar code cannot be displayed.

6. Text: bar code printed content

498) this. width = 498; 'onmousewheel = 'javascript: return big (this) 'alt = bar code effect src = "http://www.bkjia.com/uploadfile/2013/0904/20130904094617982.jpg" width = 615 height = 557>

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:

   
  

    
   
<img src="test.php?codebar=BCGcode39&text=20090729"> 
   
  

PHP5 generates a barcode:

498) this. width = 498; 'onmousewheel = 'javascript: return big (this) 'alt = run instance src = "http://www.bkjia.com/uploadfile/2013/0904/20130904094617379.jpg" width = 665 height = 186>

PHP5 generates the code test. php:
