Using The Volvo 440 Diagnostic System


The Volvo 440 dates back to an era where Car manufacturers were actually helpful (or at least some of them were), and as a result has a built in Diagnostic system. No going to the Garage to have fault codes read, so long as you know how to use the system.

POST Data going missing in PHP

I came across an incredibly frustrating issue earlier today, whilst building a class to parse data and insert it into a database I discovered some serious data loss. Sniffing the traffic showed the data was being submitted, but when I tried to access it in PHP bits were missing!

  1. echo $_POST['foo'] would give "blah blah blah"
  2. echo $_POST['bar'] would give "This is a block of text<br>This is line 2"
  3. echo $_POST['zulu'] would give "bah"

Unfortunately, this isn't the case! Instead number 2 returns "<br>This is line 2". How very frustrating, but thankfully I eventually found the solution

This documentation shows a workaround that can be used in order to get KDE to remember the settings.
