HTTP Caching

About the exam

To take the exam, you should buy the exam voucher. The usual price is 250 euros. However, Symfony offers some discounts about two times a year. Usually, it is on Black Friday, and sometimes mid-June or whenever the Symfony exam version is announced. Deals go up to 40%, so I recommend that you aim to buy a voucher at that time.

Buying a voucher

After successful checkout, you should see an email with "Order Confirmation and Vouchers for the Symfony Certification Exam" subject in your inbox. The contents of the email body should be something like this:

If you are already a member of SymfonyConnect, just navigate https://certification.symfony.com/manager/voucher(step 3), select the relevant Symfony version from the dropdown and paste the voucher code inside the input. That's it, you are ready to schedule the exam date.

Scheduling exam date

Once you are prepared and feel comfortable taking the exam, go to the "My Vouchers" section and select the date and time of your exam. I suggest that you schedule the exam in the morning rather than afternoon or evening because you will be fresh and full of energy after the night's sleep. This is how the scheduled exam for looks like:

Shortly after your date and time confirmation, Symfony should email you the confirmation notice and a check requirements link. I recommend testing your exam environment on that link to eliminate any late surprises before the exam. Also, be advised that only the Google Chrome browser is supported.

In the "My Vouchers" section, there should be a piece of information about the scheduled exam, with the additional link, which you will access at the exam time.

General overview

More info coming soon.

Successful exam delivery

After the successful exam delivery, you should receive an official email from Symfony about your exam result in a few business days. Here is an example of that email:

Also, in the "My Exams History" you should be able to see the results:

That's about it. Congratulations on getting certified :).

Thanks

Special thanks to Thomas Berends for compiling the list of Symfony certification exam preparation resources, which author of this repository used in order to prepare for Symfony certification exams. This repository covers missing parts, as the original repo did not provide any code examples to tinker with.

Also, thanks to webmozart for open-sourcing the Symfony Forms workshop repository, which was used as the initial code base for this repository.

Sanitize untrustworthy HTML user input (Symfony integration for https://github.com/tgalopin/html-sanitizer)

html-sanitizer is a library aiming at handling, cleaning and sanitizing HTML sent by external users (who you cannot trust), allowing you to store it and display it safely. It has sensible defaults to provide a great developer experience while still being entierely configurable.
