Zend_Pdf not compatible with remote storage

[Nuranto]

Summary

Zend_Pdf is not compatible with remote storage.

Examples

$pdf = new \Zend_Pdf();
$pdf->save($remoteStoragePath);

\Zend_Pdf::load($remoteStoragePath);

Zend_Pdf uses fopen / fclose / etc... so it obviously fails when using remote storage.

Proposed solution

It seems laminas decided to drop pdf support, which leave us without simple solution.

Here are possible solutions :

• Switch all PDF-related code to another library
• Dev a cusom PDF library (but why reinvent wheel ?)
• Improve/evolve current Zend_Pdf to fix compatibility issues.

Hello @Nuranto,

Thanks for the report and collaboration!

I would like to suggest that after save the PDF, use putObject (in case of S3) to upload file:

$pdf->save($pdf_file_path, true);

$s3Client = new S3Client([
    'version' => 'latest',
    'region' => $this->s3client_region,
    'credentials' => [
        'key'    => $this->s3client_key,
        'secret' => $this->s3client_secret,
    ],
]);


$key = 'test/data.pdf';

$result = $s3Client->putObject([
    'Bucket' => $this->s3client_bucket_name,
    'Key'    => $key,
    'Body'   => fopen($pdf_file_path, 'r'),
]);

// Check if the upload was successful
if ($result['@metadata']['statusCode'] === 200) {
    echo 'File uploaded successfully.';
} else {
    echo 'Failed to upload file.';
}

Does this resolve your issue? or have we missed anything here?

Thanks

I already do have workarounds, it's just a shame we cannot use Zend_Pdf directly with remote storage instead of using workarounds.

At the moment, to load a pdf from remote storage, we have to first copy it to local storage. Or perhaps load contents from remote storage, and load pdf with content.
Same thing for saving, as you do in your proposed workaround.

When Zend_Pdf could simply load/save directly from/to remote storage.

I think since Magento2 took the decision to support Remote Storage, it should do it fully, not just for specific cases.
