Possible Values For: PHP_OS

Question

Is there a place to find a list of the possible values for the PHP predefined constant PHP_OS ? I\'d like to use this value for a system requirements check, but

Answer 1

PHP passes through the uname, except on Windows (WINNT) and Netware (Netware). See Wikipedia for a non-exhaustive list of values not mentioned in your question:

• CYGWIN_NT-5.1
• IRIX64
• SunOS
• HP-UX
• OpenBSD (not in Wikipedia)
