Most of the code used at [[https://www.museum-digital.org][museum-digital]] is written in PHP. To keep a uniform code style throughout the code, we use [[https://github.com/squizlabs/PHP_CodeSniffer][PHP Code Sniffer]].
The file _md_phpcs_rules.xml_ contains the main style guide. When rewriting files to fit the uniform style rules, _md_phpcs_rules_basic.xml_ comes in handy as a first step. It contains the same rules, excluding some which require or encourage a more in-depth look at the code (the prohibition of procedural-style calls to mysqli functions is e.g. a good opportunity to check the efficiency of queries).
