Yahallo,

Currently on interruption from my mathematics degree at Imperial College London, I liked to drive my markers crazy by using PHP to do computational maths instead of Python or MatLab.

Usually, I work on php-src (the PHP engine) spending my time trying to enable compiler warnings, re-factoring old code, and proposing language changes to improve PHP.

PHP RFCs I wrote or am a co-author:

• Accepted:
  • Explicit octal integer literal notation
  • Saner Numeric Strings
  • Locale-independent float to string cast (Co-authored)
• Declined:
  • Namespace in Core (Co-authored)
  • Rename T_PAAMAYIM_NEKUDOTAYIM to T_DOUBLE_COLON (Co-authored)
• Controversial:
  • Deprecate PHP Short open tags (Initial RFC and Follow-up RFC)

I'm one of the main maintainers of the French PHP documentation translation, keeping it up to date with the English version, in which I also contribute to improve it (and give myself more work at the same time).
Notable PHP documentation contributions:

• Type Declaration page
• Improvement to the error handling and exception docs

I also maintain the PHP CSV extension which is an attempt at improving handling of CSV strings and files in PHP compared to the currently built-in CSV functions.
You can install it via PECL.

Sponsoring me is a way to contribute back to PHP by allowing me to spend time doing some of the boring work on the engine and docs. Or letting me work on some new extensions for PHP.
