[PHP]
; PHP is also a constantly evolving tool, and its functionality is constantly being truncated.
; And PHP.ini's settings change can reflect a considerable change,
; It's good to study php.ini before using the new PHP version.
;;;;;;;;;;;;;;;;;;;
; about this document;
; This file controls many aspects of PHP's view. In order for PHP to read this file, it must be named
; ' PHP.ini '. PHP will look for the file in these places: current working directory; environment variable PHPRC
; The path specified at compile time.
; Under Windows, the path at compile time is the Windows installation directory.
; In command-line mode, the php.ini lookup path can be substituted with the-c parameter.
; The syntax of the file is very simple. Blank characters and semicolons '; ' The starting line is simply ignored (as you might
; guessed the same). Chapter headings (For example: [Foo]) are also simply ignored, even though they may in the future
; There is a sense of some kind.
; The instruction is specified using the following syntax:
; Indicates identifier = value
; directive = value
; Indicates that the identifier is case-sensitive *-Foo=bar differs from foo = bar.
; The value can be a string, a number, a PHP constant (such as: E_all or M_PI), the INI constant in the
; One (on, Off, True, False, Yes, No and None), or an expression
; (such as: E_all & ~e_notice), or a string enclosed in quotation marks ("foo").
; INI file is limited to bitwise operators and parentheses.
; | Bitwise OR
; & Bitwise AND
; ~ Bitwise NOT
; ! Boolean not
; The Boolean flag can be used 1, on, True or Yes to put these values in the open state.
; They are available in 0, off, False or No These values are turned off.
; An empty string can be used after the equal sign to not write anything, or with the None keyword:
; Foo =; Place Foo as an empty string
; foo = none; Place Foo as an empty string
; Foo = "None"; Place Foo As String ' None '
; If you use constants in your value settings, and these constants belong to the extended library of dynamic push-in (not the extension of PHP, it is
; Zend extension), you can only use these constants after you have transferred the lines of these extensions * *.
; All values set in the Php.ini-dist file are the same as the built-in default values (this is to say, if php.ini
; is not used or you delete these lines, the default value is the same).
; Language Options;
Engine = On
; Makes PHP scripting language engine (PHP scripting language Engine) valid under Apache.
Short_open_tag = On
; Allow tags will be recognized.
Asp_tags = Off
; Allow Asp-style <%%> tags
Precision = 14
; Number of significant digits when floating-point type is displayed
Y2k_compliance = Off
; Whether to open 2000 adaptation (may cause problems in non-Y2K adapted browsers)
output_buffering = Off
; The output cache allows you to send headers (headers, including cookies) even after the output body content.
; The cost is that the output layer slows down a little bit. You can use output caching to open the output cache at run time.
; Alternatively, set the indicator to on to make the output cache for all files open.
Output_handler =; You can redirect all the output of your script to a function,
; Doing so can be useful for handling or logging it.
; For example, if you set this output_handler to "Ob_gzhandler",
; The output is transparently compressed for a browser that supports gzip or deflate encoding.
; Set an output processor to automatically turn on the output buffer.
Implicit_flush = Off
; Forcing flush (refresh) allows PHP to tell the output layer to automatically refresh its data after each output block.
; This is equivalent to calling the flush () function after each print () or echo () call and each HTML block.
; Opening this setting causes serious runtime conflicts and is recommended to be opened only during the debug process.
Allow_call_time_pass_reference = On
; Whether to allow arguments to be passed by reference when forcing a function call. This approach has been protested,
; and may no longer be supported in future versions of Php/zend.
; Encouraged to specify which parameters are passed by reference in the function declaration.
; You are encouraged to try to close this option and confirm that your script still works to ensure that in future versions of the language
; They can still work. (You'll get a warning every time you use this feature, and the argument will be by value instead of by reference
; Delivery).
; Safe Mode
Safe_mode = Off
Safe_mode_exec_dir =
Safe_mode_allowed_env_vars = Php_
; ？ Setting Certain environment variables
; ？ May is a potential security breach.
; The indicator contains a comma-delimited list of prefixes. In Safe mode, users can only replace
; The value of the environment variable that begins with the prefix listed here.
; By default, users will only be able to set environment variables that start with PHP_ (for example, Php_foo=bar).
; Note: If this instruction is empty, PHP will let the user change any environment variable!
Safe_mode_protected_env_vars = Ld_library_path
; This instruction contains a comma-delimited list of environment variables that the end user will not be able to change with putenv ().
; These variables are protected even when the Safe_mode_allowed_env_vars is set to allow.
Disable_functions =
; This directive allows you to invalidate a particular function for security reasons.
; It accepts a comma-delimited list of function names.
; This instruction * is not affected by the open security mode.
; The color of the syntax highlighting mode.
; You can work as long as you can accept something.
highlight.string = #DD0000
Highlight.comment = #FF8000
Highlight.keyword = #007700
highlight.bg = #FFFFFF
Highlight.default = #0000BB
highlight.html = #000000
; Misc Miscellaneous
expose_php = Off
; Decide whether PHP will indicate the fact that it is installed on the server (for example: add it-php-to the Web service
; The signal sent).
; (My personal opinion, in the presence of what power-by header, turn this off.) ）
; It will not be a security threat, but it makes it possible to check if PHP is installed on your server.
; Resource Limits;
Max_execution_time = 30; Maximum execution time per script, per second
Memory_limit = 8388608; The maximum amount of memory a script can use (this is 8M
; Error handling and logging;
; Error control and registration;
; The error report is bitwise. Or add up the numbers to get the error report level you want.
; E_all-All errors and warnings
; E_error-Fatal Run-time error
; E_warning-run-time warning (non-fatal error)
; E_parse-Compile-time parse error
; E_notice-Runtime Reminders (these are often caused by bugs in your code,
, or it may be intentional behavior. (for example, an uninitialized variable is automatically initialized to a
The fact of an empty string uses an uninitialized variable)
; E_core_error-fatal error occurred during initialization of PHP startup
; E_core_warning-Warning (non-fatal error) occurred during initialization of PHP startup
; E_compile_error-Compile-time fatal error
; E_compile_warning-Compile-time warning (non-fatal error)
; E_user_error-error message generated by the user
; E_user_warning-user-generated warning message
; E_user_notice-user-generated reminder message
; Example:
; error_reporting = E_all & ~e_notice; Show all errors except reminders
; error_reporting = e_compile_error| e_error| E_core_error; Show only Errors
error_reporting = E_all & ~e_notice; Show all errors except reminders
Display_errors = on; Display error message (as part of output)
; On the final published Web site, it is strongly recommended that you turn off this feature and use the
; Error log instead (see below).
; Continue to make display_errors available in the final published Web site
; Expose some information about security, such as the file path on your Web service,
; Your database planning or other information.
Display_startup_errors = OFF; Even when Display_erroes is open, it happens in PHP's boot steps
; Error will not be displayed.
; It is strongly recommended to keep the display_startup_errors closed,
; In addition to the process of error-changing.
Log_errors = OFF; Error logged in log file (server specified log, stderr standard error output, or Error_log (below))
; As stated above, it is strongly recommended that you log errors in the final published Web site
; Replace the direct error output.
Track_errors = OFF; Save most recent error/warning message to Variable $php _errormsg (Boolean)
; error_prepend_string = ""; String to output before the error message
; error_append_string = ""; The string to output after the error message
; error_log = filename; Logging the error log in the specified file
; error_log = syslog; Logging error log in Syslog (NT event Log, Windows 95 is not valid)
warn_plus_overloading = OFF; Warning when ' + ' is used for strings
; Data handling;
Variables_order = "Egpcs"; This instruction describes the PHP record
; GET, POST, Cookie, environment and built-in the order of these variables.
; (represented by G, P, C, E & S, usually referred to as egpcs or GPC).
; The new value replaces the old value by a left-to-right record.
Register_globals = on; Whether to register these egpcs variables as global variables.
; If you don't want the user data to be out of scope, you might want to close it.
; It's more meaningful to connect with track_vars-so you can get through
; $HTTP _*_vars[] Array accesses all the GPC variables.
REGISTER_ARGC_ARGV = on; This instruction tells PHP whether to declare argv and ARGC variables
; (Note: Here argv is an array, ARGC is the number of variables)
; (which contains data from the Get method).
; If you don't want to use these variables, you should turn it off to improve performance.
