A simple example of generating barcodes with PHP5_PHP Tutorial

The software supports both PHP4 and PHP5 versions. The PHP5 version is used in this article. Be sure to turn on PHP's GD module before use. This is php_gd2.dll in Windows and gd.so in Linux. Extract the compressed file to Apache and execute http://localhost/barcode/index.php. PHP5 generates barcodes as shown below:

1. Type: Select the barcode type

2. Output: Output image format

3. Thickness: Barcode height

4. Resolution: barcode size

5. Font: text size below the barcode, or no text displayed

6. Text: barcode printed content

Of course, this PHP5 barcode generation program only generates text into barcodes, but it cannot be flexibly embedded in other PHP programs when used. I will compress the test in the package Some adjustments have been made to .php to make it flexible for use in other programs. When running, just pass 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

mytest.php code:

<span style="COLOR: #0000ff"><pre class="brush:php;toolbar:false"><ol class="dp-xml"><li class="alt"><span><strong><font color="#006699"><span class="tag"><span class="tag-name">img</span></span></font></strong><span><font color="#000000"> </font></span><span class="attribute"><font color="#ff0000">src</font></span><span><font color="#000000">=</font></span><span class="attribute-value">"test.php?codebar=BCGcode39&text=20090729"</span><span class="tag"><strong><font color="#006699">></font></strong></span><span><font color="#000000"> </font></span></span></li></ol>
