+ +// if your binary data is not matching the template you provided this will throw an `\Exception`: +$parser = new TemplateParser(); +$object = $parser->parseBinary($data, $template); + +// there is also a convenience function if you parse binary data from base64: +$object = $parser->parseBase64($data, $template); +``` + +You can use this function to make sure your data has exactly the format you are expecting. + +### Navigating decoded data + +All constructed classes (i.e. `Sequence` and `Set`) can be navigated by array access or using an iterator. +You can find examples +[here](https://github.com/fgrosse/PHPASN1/blob/f6442cadda9d36f3518c737e32f28300a588b777/tests/ASN1/Universal/SequenceTest.php#L148-148), +[here](https://github.com/fgrosse/PHPASN1/blob/f6442cadda9d36f3518c737e32f28300a588b777/tests/ASN1/Universal/SequenceTest.php#L121) and +[here](https://github.com/fgrosse/PHPASN1/blob/f6442cadda9d36f3518c737e32f28300a588b777/tests/ASN1/TemplateParserTest.php#L45). + + +### Give me more examples! + +To see some example usage of the API classes or some generated output check out the [examples](https://github.com/fgrosse/PHPASN1/tree/master/examples). + + +### How do I contribute? + +If you found an issue or have a question submit a github issue with detailed information. + +In case you already know what caused the issue and feel in the mood to fix it, your code contributions are always welcome.
