PHP Barcode Generator Script User Manual
 
Installing the PHP Barcode Script
The PHP Barcode Generator is a server-side script that adds barcode
generation capability to any PHP-compatible website. Once
installed, linear barcode images are generated on the server in memory and
streamed to the client without saving any temp files on the server.
- After extracting the install files from the demo or purchased download, copy the
necessary files
to a webserver where PHP script processing is enabled. Each file contains the
name of the barcode symbology that it supports. When in doubt as to which file to use,
consider using idautomation-code128.php.
-
Open
the file in a web browser and verify that a default barcode image is displayed. If it
is not, ensure that the files are installed in the proper folder on the server
and verify that PHP script processing is active in the folder where the
file resides.
- Integrate the resulting URL into your web application as a dynamic IMG tag
and add the D= parameter for the data that
is being encoded into a barcode. This script may be streamed
in the same way as the ASP Barcode Server for IIS which offers several examples
for
integrating streaming barcodes.
- Refer to the Barcode Script Parameters section
of this user guide to modify additional parameters such as apply tilde, font
size and more. For example, the following parameters can be utilized to encode
the text of "123456", disable the optional check digit in Code 39 and set the bar
height to 30 pixels:

specific requirements dictate otherwise.

PHP barcode generation. If additional properties or symbologies are needed, consider
the Online
Barcode Generator Service or of one of IDAutomation's
compiled barcode products that incorporate streaming capability, such as
the ASP Barcode Server for IIS
and the Java Servlet, which is part of the
Java Barcode Package.
