barcode39 generation in php - php

Question

I have gone through this link for the barcode generation.
I have downloaded the zip file and tested in my local host. It worked there, after that I have kept the files in my project and checked there. It doesn't work instead it gave me corrupted image as below.
GIF87aP���������,P���������p�قzu���b�a�I���xmZơFÌ,��}r�~���[�pH��(��>V�ie����q����dZΰ�+�����'�=]��n9?^wv�g��W���UƵ���h�8x(h�����GG� I��z�I:�j�y*zY�ij�::[� �Z+p+�J�k�Z�K�k�|��L�)����`N���qt���r���"�P���>�NA<~��]�p��{���!D +Z�ؠ;
Now I've created a sample file in the same location in my project with simple <?php ?> tags and kept the code
include "Barcode39.php";
// set Barcode39 object
$bc = new Barcode39("abc");
// display new barcode
$bc->draw();
again it worked in the sample file which I have kept in the project, but it is not working in the project related file.
Not getting the issue here.

Answer 1

Its perfectly working fine, make sure Barcode39.php in the same location.
As well it required PHP:GD, check again its install or not.
(Include could be issue if you are using any other framework)
I tested and got the below output
You can also use the below code to generate the gif file of barcode and link it anywhere in any page. you will not face any issue related to using html tags.
<?
// include Barcode39 class
include "Barcode39.php";
// set object
$bc = new Barcode39("123-ABC");
// set text size
$bc->barcode_text_size = 5;
// set barcode bar thickness (thick bars)
$bc->barcode_bar_thick = 4;
// set barcode bar thickness (thin bars)
$bc->barcode_bar_thin = 2;
// save barcode GIF file
$bc->draw("barcode1.gif");
?>
and include this file in the src attr of the image tag like
<img src="http://localhost/yourbarcodefilepath" alt="barcode"/>
then it will work
