Big cabbage core rookie tutorial! :)
Key or usually, I have made a color to calm!

I refer to the online and official content, then I have added some comments. There is also imperfect, please advise!
[Php]; PHP is still a constantly developing tool, its function is still constantly being reduced; and the PHP.ini setting change can reflect the considerable change, and before using the new PHP version, study PHP.ini will have benefits
;;;;;;;;;;;;;;;;;; About this file; ;;;;;;;;;;;;;;;;
This file controls many views of PHP. In order to let PHP read this file, it must be named; 'php.ini'. PHP will look for this file in these places: the current working directory; environment variable phprc; indicated path; the path specified when compiling. Under Windows, the path to compile is a Windows installation directory. In command line mode, the PHP.INI's lookup path can be replaced with the -c parameter.
The syntax of the file is very simple. Blank characters and semicolons ';' starting rows are simply ignored (just like you may; guessing). The chapter title (for example: [foo]) is also simply ignored, even if they may; there is a meaning. The indication is specified using the following symptom: indicating the identifier = value; Directive = Value; Indicates the identifier is * case sensitive * - foo = bar is different from foo = bar. The value can be a string, a number, a PHP constant (such as: e_all or m_pi), in constant; one (ON, OFF, TRUE, FALSE, YES, NO AND NONE), or an expression (Eg: e_all & ~ e_notice), or the string ("foo") enclosed with quotation marks ("foo").;; The expression of the INI file is limited to the position operator and parentheses. (Bitwise OR; & Bitwise and; ~ Bitwise Not;! Boolean NOT;; Boolean flag can be placed in the state of the value of 1, ON, TRUE or YES. They can be placed in the relationship with 0, OFF, FALSE OR NO. An empty string can be used in the equal sign, or use the None keyword:;;; foo =; foo = none; foo = none; set FOO to an empty string; foo = "none"; set the FOO to string 'none'; if you use constants in your value setting, these constants belong to the dynamically transferred extension library (not PHP expansion, that is, the extension of Zend), you can only After transferring these extended lines * * Use these constants. All the values set in the php.ini-dist file are the same as the built-in default (this is said, if pHP.ini; is not used or you delete these rows, the default value is the same).

Engine = ON; makes PHP Scripting Language Engine (PHP Scripting Language Engine) is valid under Apache. Short_open_tag = ON; Allow Tags to be identified. ASP_TAGS = OFF; allows asp-style tags precision = 14; the number of valid bits when the floating point type is displayed Y2K_COMPLIANCE = Off; whether to open 2000 adaptation (may result in problems in a browser adaptable in non-Y2K)
Output_buffering = OFF
(If this is OFF, you can solve it in the program); output cache allows you to send Header after outputting the text content, including a cookies
The cost is that the output layer slows down a little speed. You can use the output cache to turn on the output cache when running,; or here will be set to ON to make the output cache of all files open. Output_handler =; You can redirect all output to a function of your script,; doing you may be useful for processing or logging it. For example, if you set this output_handler, the output will be transparently compressed for browser that supports Gzip or Deflate encoded. The output processor is set automatically opens the output buffer.
Implicit_flush = OFF; Force Flush (refresh) Let PHP tell the output layer to automatically refresh their own data after each output block. This is equivalent to calling a flush () function after each print () or echo () call and each HTML block. Opening this setting causes a serious runtime conflict, it is recommended to open only during the Debug process.
ALLOW_CALL_TIME_PASS_REFERENCE = ON; Whether the forced function is transferred according to the reference to transfer parameters. This approach is protest, and it may not be supported in the future version of PHP / Zend. The method of encouragement specifies which parameters is transmitted by reference to the function declaration. You are encouraged to try to close this option and confirm that your script will still work normally to ensure that in the future version of the language; they still work. (You will get a warning every time you use this feature, and the parameters will be valued instead of reference; delivery).
; SAFE MODE security 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 indicator contains a comma-separated prefix list. In the security mode, the user can only replace; the value of the environment variable at the beginning of the prefix listed here. By default, the user will only set the environment variable starting with PHP_ (eg pHP_foo = BAR). ; Note: If this indication is empty, the PHP will let the user change any environment variable!
SAFE_MODE_PROTECTED_ENV_VARS = ld_library_path; This indicator contains a comma-separated environment variable list, which will not change with Putenv (). These variables are protected even in the case where SAFE_MODE_ALOWED_ENV_VARS is set to allow.
Disable_functions =; This indication allows you to fail for a particular function for security. It accepts a list of functions separated by commas. This indication * is not affected by * security mode.
The color of the syntax highlight mode. As long as it can be accepted. Highlight.string = # dd0000 highlight.comment = # ff8000 highlight.keyword = # 007700 highlight.bg = #fffffff highlight.default = # 0000bb highlight.html = # 000000
MISC miscellaneous eXPOSE_PHP = OFF; determine if the PHP indicates that it is mounted on the server (for example: adding on it-php- to the web service; sent on the signal). (I personally comment, when there is a Power-by HEADER, turn this off.); It does not have a security threat, but it makes it possible to check if PHP is installed on your server.

Or add a number to get the desired error report level. ; E_ALL - All errors and warnings; E_ERROR - Fatness running error; e_warning - runtime warning (non-poor misalignment); E_PARSE - Compile error; E_NOTICE - Running (these often is your code) BUG is caused; it may also be caused by intentional behavior. (such as: automatically initializing the unin-initialized variable to one; use an uninitialized variable in the facts of the empty string)
E_CORE_ERROR - A fatal error occurred during initialization during PHP; E_CORE_WARNING - Warning (Non-Derived Wrong) during initialization during PHP startup; E_Compile_ERROR - compile life; E_Compile_Warning - Compile time warning (Non-fatal Sex error); E_USER_ERROR - the error message generated by the user; E_USER_WARNING - the warning message generated by the user; E_USER_NOTICE - the user generated alert message; example: ire_reporting = e_all & ~ e_notice; display all errors, except for reminding; error_reporting = e_compile_ERROR | E_ERROR | E_CORE_ERROR; only the error error Error_Reporting = E_ALL & ~ E_NOTICE; display all errors, in addition to reminding Display_errors = ON; display error message (as part of the output)
(If you are ON here, there is no change in the page. So you can write a line in the program: Error_reporting (7); or use isset or empty when POST, Get variables; in the final release On the Web site, it is highly recommended that you turn off this feature and use it; the error log is replaced (see below). In the final released Web site continues to make Display_ERRORS valid; expose some information about security, such as file paths on your web service,; your database planning or other information. Display_startup_errors = OFF; even when Display_ERROES is opened, in the step of starting in PHP; error is not displayed. It is highly recommended to keep display_startup_errors to close, except for the wrong process. Log_ERRORS = OFF; record errors in the log file (the server specified by the server, STDERR standard error output, or error_log)); as in the above description, it is highly recommended that you have a logging error in the finally released Web site; replace Direct error output. TRACK_ERRORS = OFF; save the most recent error / warning message in the variable $ php_errorsg (boolean); error_prepend_string = ""; error_append_string = ""; Error_Append_string = ""; String output after the error message; error_log = filename Record the error log in the specified file; error_log = syslog; record error logs in system log Syslog (Event log under NT, WINDOWS 95 is invalid) WARN_PLUS_OVERLOADING = OFF; when the ' ' is used for strings

Register_globals = on; whether these EGPCS variables are registered as global variables. If you don't want user data, you may want to close it. This is even more meaningful to TRACK_VARS - so that you can pass; $ http _ _ vars [] array access all GPC variables.
Register_argc_argv = ON; This indication tells PHP to declare Argv and Argc variables; (Note: here Argv is array, ARGC is variable); (which contains data from the GET method). If you don't want to use these variables, you should turn off it to improve performance.
TRACK_VARS = ON; An array of $ http _ * _ vars [] is valid, here * is used in use; ENV, POST, GET, Cookie or Server replace post_max_size = 8m; PHP will accept the maximum size of the POST data accepted.
GPC_ORDER = "GPC"; this indication is opposed. Use Variables_Order instead.
Magic quotes magic_quotes_gpc = ON; use magic reference in GET / POST / COOKIE data; (in this way, huh, the so-called Magic Quotes should refer to control characters with escape values, such as'. ...) Magic_quotes_Runtime = Off; uses the data generated at runtime Use the magic reference, for example: data obtained with the SQL query, with the data obtained with the exec () function, etc. Magic_quotes_sybase = off; use the Sybase form in the form of magic reference ( Use '' to get rid of 'without "); automatically add file auto_prepend_file = auto_APpend_file = before and after PHP documentation
Like 4.04B4, PHP is always encoded by default in the "Content-Type:" header. To make the output character set, as long as the setting is empty. ; PHP's built-in default value is text / html default_mimetype = "text / html"; default_charset = "ISO-8859-1"

[Syslog] define_syslog_variables = OFF; whether various system log variables are defined; such as $ log_pid, $ log_cron, and so on. It is a good idea to turn off it is an improvement. When run, you can call the function define_syslog_variables () to define these variables.
