My php3.ini

[PHP_3]

;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; This file controls many aspects of PHP's behavior. In order for PHP to
; read it, it must be named 'php3.ini'. PHP looks for it in the current
; working directory, in the path designated by the environment variable
; PHPRC, and in the path that was defined in compile time (in that order).
; Under Windows, the compile-time path is the Windows directory. The
; path in which the php3.ini file is looked for can be overriden using
; the -c argument in command line mode.
;
; The syntax of the file is extremely simple. Whitespace and Lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future (they probably won't).
;
; Options are specified using the syntax key = value or key = "complex value".
; Key names are *case sensitive*. foo = bar is different from FOO = bar.
; 'value' can be any number, word or keyword (keywords are On, Off, True,
; False, Yes and No, and are case insensitive).
; 'complex value' can be just about anything, expcept for " and a newline
; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No.
;
; All the values in the php3.ini-dist file correspond to the builtin
; defaults (that is, if no php3.ini is used, or if you delete these lines,
; the builtin defaults will be identical).

                                                                ; these variables by calling define_syslog_variables()
