Magic quotes is a misguided feature of PHP that modifies user input to PHP pages so that the input can be used directly in SQL statements. This violates the programing principle of only escaping data when it is necessary and results in all kinds of weird edge cases.
This feature was deemed so misguided that it was deprecated in PHP 5.3 and removed entirely from PHP 5.4. The DP code base has relied on magic quotes to function from the beginning of the project in 2000.
I’m very happy to report that after much development and validation effort, we’ve removed the dependency on magic quotes from the DP code base! The work was done over the course of a year, primarily by myself with help from jmdyck, and validated by a team of squirrels (shout-out to wfarrell and srjfoo) and other volunteers. It was rolled out in production on November 5th and has been almost 100% bug-free – quite an accomplishment given how much of the code was impacted. A huge thank you to the team who helped make this possible!
The biggest win is our ability to run the DP code on much more recent versions of PHP all the way up to, and including 5.6.1
RIP magic quotes.
