There is a library for this BarCode PHP. You just need to include a few files:
这个BarCode PHP有一个库。你只需要包含几个文件：
require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');
You can generate many types of barcodes, namely 1D or 2D. Add the required library:
您可以生成多种类型的条形码，即一维或二维。添加所需的库：
require_once('class/BCGcode39.barcode.php');
Generate the colours:
生成颜色：
// The arguments are R, G, and B for color.
$colorFront = new BCGColor(0, 0, 0);
$colorBack = new BCGColor(255, 255, 255);
After you have added all the codes, you will get this way:
添加完所有代码后，您将得到这样的结果：
Example
例子
Since several have asked for an example here is what I was able to do to get it done
由于有几个人要求在这里举个例子，这是我能够做的事情
require_once('class/BCGFontFile.php');
require_once('class/BCGColor.php');
require_once('class/BCGDrawing.php');
require_once('class/BCGcode128.barcode.php');
header('Content-Type: image/png');
$color_white = new BCGColor(255, 255, 255);
$code = new BCGcode128();
$code->parse('HELLO');
$drawing = new BCGDrawing('', $color_white);
$drawing->setBarcode($code);
$drawing->draw();
$drawing->finish(BCGDrawing::IMG_FORMAT_PNG);
If you want to actually create the image file so you can save it then change
如果您想实际创建图像文件以便您可以保存它然后更改
$drawing = new BCGDrawing('', $color_white);
to
到
$drawing = new BCGDrawing('image.png', $color_white);
