Each barcode type is provided as a single unencrypted PHP file, which provides extremely fast barcode generation with very little overhead. Each PHP barcode script file is provided in pure PHP source code form, so it may be used natively and customized or integrated within any web application. The PHP barcode images generated are simple black and white bit-mapped BMP images (1bpp) and are very small in size compared to JPEG or GIF images; the average generated barcode size is usually less than 2KB.

The following source code example demonstrates a simple method used to create dynamic barcodes within a PHP script:

<html><body>
<p>This web page uses PHP code to create a barcode.</p>
<?php
$BarcodeData = "123456789012";
?>
<p><img src="idautomation-code128.php?Barcode=<?=$BarcodeData;?>"></p>
</body></html>

	<div class="row">
<div class="col-md-4">
<form method="post">
<div class="row">
<div class="col-md-8">
<div class="form-group">
<label>Product Name or Number</label>
<input type="text" name="barcodeText" class="form-control" value="<?php echo @$_POST['barcodeText'];?>">
</div>
</div>
</div>
<div class="row">
<div class="col-md-6">
<div class="form-group">
<label>Barcode Type</label>
<select name="barcodeType" id="barcodeType" class="form-control">
<option value="codabar" <?php echo (@$_POST['barcodeType'] == 'codabar' ? 'selected="selected"' : ''); ?>>Codabar</option>
<option value="code128" <?php echo (@$_POST['barcodeType'] == 'code128' ? 'selected="selected"' : ''); ?>>Code128</option>
<option value="code39" <?php echo (@$_POST['barcodeType'] == 'code39' ? 'selected="selected"' : ''); ?>>Code39</option>
</select>
</div>
</div>
</div>
<div class="row">
<div class="col-md-6">
<div class="form-group">
<label>Barcode Display</label>
<select name="barcodeDisplay" class="form-control" required>
<option value="horizontal" <?php echo (@$_POST['barcodeDisplay'] == 'horizontal' ? 'selected="selected"' : ''); ?>>Horizontal</option>
<option value="vertical" <?php echo (@$_POST['barcodeDisplay'] == 'vertical' ? 'selected="selected"' : ''); ?>>Vertical</option>
</select>
</div>
</div>
</div>
<div class="row">
<div class="col-md-7">
<input type="hidden" name="barcodeSize" id="barcodeSize" value="20">
<input type="hidden" name="printText" id="printText" value="true">
<input type="submit" name="generateBarcode" class="btn btn-success form-control" value="Generate Barcode">
</div>
</div>
</form>
</div>
</div>

Step2: Get Barcode Generator Library
We need to download Barcode generate PHP library to create Barcode . In this example we have already downloaded barcode.php and used to create Barcode. The library has
options to create Barcode with type Codabar, Code128, Code39 and Barcode display type Horizontal and Vertical. It also supports options for size (10, 20 and 400 maximum) and option to display Barcode with text. So we will handle all these options in this example.

Step3: Generate Barcode with PHP
Now on Form submit, we will generate Barcode by passing items details to library file barcode.php and display created Barcode in img.

<?php
if(isset($_POST['generateBarcode'])) {
$barcodeText = trim($_POST['barcodeText']);
$barcodeType=$_POST['barcodeType'];
$barcodeDisplay=$_POST['barcodeDisplay'];
$barcodeSize=$_POST['barcodeSize'];
$printText=$_POST['printText'];
if($barcodeText != '') {
echo '<h4>Barcode:</h4>';
echo '<img class="barcode" alt="'.$barcodeText.'" src="barcode.php?text='.$barcodeText.'&codetype='.$barcodeType.'&orientation='.$barcodeDisplay.
'&size='.$barcodeSize.'&print='.$printText.'"/>';
} else {
echo '<div class="alert alert-danger">Enter product name or number to generate barcode!</div>';
}
}
?>
