Hi, it was a great explanation however you miss the fact, if you watch your own video on right side of php docs, you will see another php function which was released in php 8.3 ( last year in november) called json_validate. So i recommend you edit and update the video with this recent function.
Thanks. ;)

[@dave-hollingworth]

Hi - you're right, the json_validate function is also available and will validate a JSON string. The documentation is here if anyone wants it: www.php.net/manual/en/function.json-validate.php
I did consider including it in the video, however, as it states in the aforementioned documentation, "Caution: Calling json_validate() immediately before json_decode() will unnecessarily parse the string twice, as json_decode() implicitly performs validation during decoding.
json_validate() should therefore only be used if the decode JSON payload is not immediately used and knowing whether the string contains valid JSON is needed."
So I decided not to include it as we're going to call json_decode anyway to get a parsed version of the string.
If I ever update the video I will mention this though, you're right that developers should at least be aware of it. Thank you for contributing!

Please can you make a video about how pages can be dynamically updated based on an HTML form being written similar to pages that show weak and strong passwords based on the user's input.
Thanks, Dave
