PHP.INI
[PHP]

;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; This file controls many aspects of PHP's behavior.  In order for PHP to
; read it, it must be named 'php.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 php.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.
;
; Directives are specified using the following syntax:
; directive=value
; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
;
; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
; (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo").
;
; Expressions in the INI file are limited to bitwise operators and parentheses:
; |				bitwise OR
; &				bitwise AND
; ~				bitwise NOT
; !				boolean NOT
;
; 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.
;
; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword:
;
;   foo=; sets foo to an empty string
;	foo=none		; sets foo to an empty string
;	foo="none"	; sets foo to the string 'none'
;
; If you use constants in your value, and these constants belong to a dynamically
; loaded extension (either a PHP extension or a Zend extension), you may only
; use these constants *after* the line that loads the extension.
;
; All the values in the php.ini-dist file correspond to the builtin
; defaults (that is, if no php.ini is used, or if you delete these lines,
; the builtin defaults will be identical).


;;;;;;;;;;;;;;;;;;;;
; Language Options ;
;;;;;;;;;;;;;;;;;;;;

engine=On	; Enable the PHP scripting language engine under Apache
short_open_tag=On	; allow the <? tag.  otherwise, only <?php and <script> tags are recognized.
asp_tags=Off ; allow ASP-style <% %> tags
precision=14	; number of significant digits displayed in floating point numbers
y2k_compliance=Off	; whether to be year 2000 compliant (will cause problems with non y2k compliant browsers)
output_buffering=Off	; Output buffering allows you to send header lines (including cookies)
; even after you send body content, in the price of slowing PHP's
; output layer a bit.
; You can enable output buffering by in runtime by calling the output
; buffering functions, or enable output buffering for all files
; by setting this directive to On.
implicit_flush=Off	; Implicit flush tells PHP to tell the output layer to flush itself
; automatically after every output block.  This is equivalent to
; calling the PHP function flush() after each and every call to print()
; or echo() and each and every HTML block.
; Turning this option on has serious performance implications, and
; is generally recommended for debugging purposes only.
allow_call_time_pass_reference=On	; whether to enable the ability to force arguments to be 
; passed by reference at function-call time.  This method
; is deprecated, and is likely to be unsupported in future
; versions of PHP/Zend.  The encouraged method of specifying
; which arguments should be passed by reference is in the
; function declaration.  You're encouraged to try and
; turn this option Off, and make sure your scripts work
; properly with it, to ensure they will work with future
; versions of the language (you will receive a warning
; each time you use this feature, and the argument will
; be passed by value instead of by reference).

; Safe Mode
safe_mode=Off
safe_mode_exec_dir=
safe_mode_allowed_env_vars=PHP_					; Setting certain environment variables
; may be a potential security breach.
; This directive contains a comma-delimited
; list of prefixes.  In Safe Mode, the
; user may only alter environment
; variables whose names begin with the
; prefixes supplied here.
; By default, users will only be able
; to set environment variables that begin
; with PHP_ (e.g. PHP_FOO=BAR).
; Note:  If this directive is empty, PHP
; will let the user modify ANY environment
; variable!
safe_mode_protected_env_vars=LD_LIBRARY_PATH		; This directive contains a comma-
; delimited list of environment variables,
; that the end user won't be able to
; change using putenv().
; These variables will be protected
; even if safe_mode_allowed_env_vars is
; set to allow to change them.


disable_functions=; This directive allows you to disable certain
; functions for security reasons.  It receives
; a comma separated list of function names.
; This directive is *NOT* affected by whether
; Safe Mode is turned on or off.


; Colors for Syntax Highlighting mode.  Anything that's acceptable in <font color=???> would work.

; Misc
expose_php=On		; Decides whether PHP may expose the fact that it is installed on the
; server (e.g., by adding its signature to the Web server header).
; It is no security threat in any way, but it makes it possible
; to determine whether you use PHP on your server or not.

; Error handling and logging ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; error_reporting is a bit-field.  Or each number up to get desired error reporting level
; E_ALL				- All errors and warnings
; E_ERROR			- fatal run-time errors
; E_WARNING			- run-time warnings (non fatal errors)
; E_PARSE			- compile-time parse errors
; E_NOTICE			- run-time notices (these are warnings which often result from a bug in
;					  your code, but it's possible that it was intentional (e.g., using an
;					  uninitialized variable and relying on the fact it's automatically
;					  initialized to an empty string)
; E_CORE_ERROR		- fatal errors that occur during PHP's initial startup
; E_CORE_WARNING	- warnings (non fatal errors) that occur during PHP's initial startup
; E_COMPILE_ERROR	- fatal compile-time errors
; E_COMPILE_WARNING	- compile-time warnings (non fatal errors)
; E_USER_ERROR		- user-generated error message
; E_USER_WARNING	- user-generated warning message
; E_USER_NOTICE		- user-generated notice message
; Examples:
; error_reporting=E_ALL & ~E_NOTICE						; show all errors, except for notices
; error_reporting=E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR	; show only errors
error_reporting= E_ALL; display all errors, warnings and notices
display_errors=On	; Print out errors (as a part of the output)
; For production web sites, you're strongly encouraged
; to turn this feature off, and use error logging instead (see below).
; Keeping display_errors enabled on a production web site may reveal
; security information to end users, such as file paths on your Web server,
; your database schema or other information.
display_startup_errors=Off		; Even when display_errors is on, errors that occur during
; PHP's startup sequence are not displayed.  It's strongly
; recommended to keep display_startup_errors off, except for
; when debugging.
log_errors=Off	; Log errors into a log file (server-specific log, stderr, or error_log (below))
; As stated above, you're strongly advised to use error logging in place of
; error displaying on production web sites.
track_errors=Off	; Store the last error/warning message in $php_errormsg (boolean)
;error_prepend_string="<font color=ff0000>"   ; string to output before an error message
;error_append_string="</font>"                ; string to output after an error message
;error_log=filename	; log errors to specified file
;error_log=syslog		; log errors to syslog (Event Log on NT, not valid in Windows 95)
warn_plus_overloading=Off		; warn if the + operator is used with strings


;;;;;;;;;;;;;;;;;
; Data Handling ;
;;;;;;;;;;;;;;;;;
; Note - track_vars is ALWAYS enabled as of PHP 4.0.3
variables_order="EGPCS"	; This directive describes the order in which PHP registers
; GET, POST, Cookie, Environment and Built-in variables (G, P,
; C, E & S respectively, often referred to as EGPCS or GPC).
; Registration is done from left to right, newer values override
; older values.
register_globals=On		; Whether or not to register the EGPCS variables as global
; variables.  You may want to turn this off if you don't want
; to clutter your scripts' global scope with user data.  This makes
; most sense when coupled with track_vars - in which case you can
; access all of the GPC variables through the $HTTP_*_VARS[],
; variables.
; You should do your best to write your scripts so that they do
; not require register_globals to be on;  Using form variables
; as globals can easily lead to possible security problems, if
; the code is not very well thought of.
register_argc_argv=On		; This directive tells PHP whether to declare the argv&argc
; variables (that would contain the GET information).  If you
; don't use these variables, you should turn it off for
; increased performance
post_max_size=8M		; Maximum size of POST data that PHP will accept.
gpc_order="GPC"	; This directive is deprecated.  Use variables_order instead.

; Magic quotes
magic_quotes_gpc=On		; magic quotes for incoming GET/POST/Cookie data
magic_quotes_runtime=Off		; magic quotes for runtime-generated data, e.g. data from SQL, from exec(), etc.
magic_quotes_sybase=Off		; Use Sybase-style magic quotes (escape ' with '' instead of \')

; automatically add files before or after any PHP document
auto_prepend_file=
auto_append_file=

; As of 4.0b4, PHP always outputs a character encoding by default in
; the Content-type: header.  To disable sending of the charset, simply
; set it to be empty.
; PHP's built-in default is text/html
default_mimetype="text/html"
;default_charset="iso-8859-1"
