The evaluation version of Aspose.BarCode for PHP via Java allows full barcode generation functionality but adds a watermark (“Aspose”) to each generated image. It also supports barcode recognition for all types; however, only Code 39 can be fully decoded. For all other symbologies, 30% of the recognized text will be replaced with asterisks ("*").
Any additional functionality—such as saving clean images, full barcode decoding, and advanced settings—requires applying a valid license.
Once a license is applied, all limitations are removed, including watermarking and masked output, unlocking full access to barcode generation and recognition capabilities.
To evaluate the full version without restrictions, you can request a 30-day temporary license.

Temporary License?
For production use, a commercial license is required. License pricing and details are available at:
Pricing for Aspose.BarCode for PHP
via Java
Every license includes:
The license is an XML file that contains essential information about your license, including:
License Type
Order ID
Product Names
the license applies toCustomer
detailsEdition Type
Serial Number
A trial license includes an additional field, LicenseExpiry
,
which specifies the expiration date.
After this date, the trial license becomes inactive.
Both trial and commercial licenses include a SubscriptionExpiry
field,
which defines the period during which you are entitled to receive product updates,
such as:
⚠️ Note: Typically, the
LicenseExpiry
date is earlier than theSubscriptionExpiry
.
Therefore, for trial licenses, theSubscriptionExpiry
has no practical effect.
⚠️ Do not modify the license file.
The license is digitally signed. Any changes — including additional spaces or line breaks — will corrupt the file and cause validation to fail.
There are two ways to apply a license in Aspose.BarCode for PHP via Java.
The license is set once and remains valid for all subsequent operations in the session. You do not need to pass it with each request.
Example: BarcodeGenerator
and BarCodeReader
$license = new License();
Assert::assertFalse($license->isLicensed());
$license->setLicense(LICENSE_PATH);
Assert::assertTrue($license->isLicensed());
$codeText = "12345678";
$encodeType = EncodeTypes::CODE_11;
$generator = new BarcodeGenerator($encodeType, $codeText);
$base64Image = $generator->generateBarCodeImage(BarCodeImageFormat::PNG, false);
// last parameter`$passLicense` has default valuse `false` and can be ommitted
Assert::assertTrue($license->isLicensed());
$reader = new BarCodeReader($base64Image, null, null);
$resultsArray = $reader->readBarCodes(false);
// parameter `$passLicense` has default valuse `false` and can be ommitted
$barCodeResult = $resultsArray[0];
$codeTextAct = $barCodeResult->getCodeText();
$codeTypeAct = $barCodeResult->getCodeTypeName();
Assert::assertTrue($license->isLicensed());
Example: ComplexBarcodeGenerator and BarCodeReader
//Prepare Mailmark Codetext
$mailmarkCAndLCodetext = new MailmarkCodetext(null);
$mailmarkCAndLCodetext->setFormat(4);
$mailmarkCAndLCodetext->setVersionID(1);
$mailmarkCAndLCodetext->setClass_("0");
$mailmarkCAndLCodetext->setSupplychainID(384224);
$mailmarkCAndLCodetext->setItemID(16563762);
$mailmarkCAndLCodetext->setDestinationPostCodePlusDPS("EF61AH8T ");
//Install License
$license = new License();
Assert::assertFalse($license->isLicensed());
$license->setLicense(PHP_LICENSE_PATH);
Assert::assertTrue($license->isLicensed());
$generator = new ComplexBarcodeGenerator($mailmarkCAndLCodetext);
$base64Image = $generator->generateBarCodeImage(BarCodeImageFormat::PNG);
Assert::assertTrue($license->isLicensed());
$barCodeReader = new BarCodeReader($base64Image, null, DecodeType::MAILMARK);
$resultsArray = $barCodeReader->readBarCodes(false);
Assert::assertEquals(sizeof($resultsArray), 1);
$resultCodeText = $barCodeReader->getFoundBarCodes()[0]->getCodeText();
Assert::assertEquals("4100016563762EF61AH8T", trim($resultCodeText));
$mailmarkCodetext = ComplexCodetextReader::tryDecodeMailmark($resultCodeText);
Assert::assertTrue($license->isLicensed());
In this mode, the license is not applied globally. Instead, it is passed explicitly with each individual request from PHP to the Java backend. Once the request completes, the license is cleared, and the system reverts to an unlicensed state.
Only three methods support the bool $passLicense parameter:
// Generation
BarcodeGenerator::generateBarCodeImage(int $format, bool $passLicense = false): string
// Recognition
BarCodeReader::readBarCodes(bool $passLicense = false): array
// Complex Barcode
ComplexBarcodeGenerator::generateBarcodeImage(int $format, bool $passLicense = false): string
Example: BarcodeGenerator and BarCodeReader
$license = new License();
License::prepareLicenseContent(TestsAssist::PHP_LICENSE_PATH);
Assert::assertFalse($license->isLicensed());
$codeText = "12345678";
$encodeType = EncodeTypes::CODE_11;
$generator = new BarcodeGenerator($encodeType, $codeText);
$base64Image = $generator->generateBarCodeImage(BarCodeImageFormat::PNG, true);
Assert::assertFalse($license->isLicensed());
$reader = new BarCodeReader($base64Image, null, null);
$resultsArray = $reader->readBarCodes(true);
$barCodeResult = $resultsArray[0];
$codeTextAct = $barCodeResult->getCodeText();
$codeTypeAct = $barCodeResult->getCodeTypeName();
Assert::assertFalse($license->isLicensed());
