Some quotes:

• May 2002: yScript -> PHP
• Why we picked PHP
  1. Designed for web scripting
  2. High performance
  3. Large, Open Source community
     • Documentation, easy to hire developers
  4. “Code-in-HTML” paradigm
  5. Integration, libraries, extensibility
  6. Tools: IDE, debugger, profiler
• ./configure –disable-all
• Security: open_basedir, allow_url_fopen = Off, display_errors = Off, safe_mode = Off; input_filter hook
• Performance: Opcode Caches, PHP Extensions in C++
• Globalization: PHP Unicode (2006)
