395 ; This directive informs PHP of which errors, warnings and notices you would like
396 ; it to take action for. The recommended way of setting values for this
397 ; directive is through the use of the error level constants and bitwise
398 ; operators. The error level constants are below here for convenience as well as
399 ; some common settings and their meanings.
400 ; By default, PHP is set to take action on all errors, notices and warnings EXCEPT
401 ; those related to E_NOTICE and E_STRICT, which together cover best practices and
402 ; recommended coding standards in PHP. For performance reasons, this is the
403 ; recommend error reporting setting. Your production server shouldn't be wasting
404 ; resources complaining about best practices and coding standards. That's what
405 ; development servers and development settings are for.
406 ; Note: The php.ini-development file has this setting as E_ALL. This
407 ; means it pretty much reports everything which is exactly what you want during
408 ; development and early testing.
409 ;
410 ; Error Level Constants:
411 ; E_ALL - All errors and warnings (includes E_STRICT as of PHP 5.4.0)
412 ; E_ERROR - fatal run-time errors
413 ; E_RECOVERABLE_ERROR - almost fatal run-time errors
414 ; E_WARNING - run-time warnings (non-fatal errors)
415 ; E_PARSE - compile-time parse errors
416 ; E_NOTICE - run-time notices (these are warnings which often result
417 ; from a bug in your code, but it's possible that it was
418 ; intentional (e.g., using an uninitialized variable and
419 ; relying on the fact it is automatically initialized to an
420 ; empty string)
421 ; E_STRICT - run-time notices, enable to have PHP suggest changes
422 ; to your code which will ensure the best interoperability
423 ; and forward compatibility of your code
424 ; E_CORE_ERROR - fatal errors that occur during PHP's initial startup
425 ; E_CORE_WARNING - warnings (non-fatal errors) that occur during PHP's
426 ; initial startup
427 ; E_COMPILE_ERROR - fatal compile-time errors
428 ; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
429 ; E_USER_ERROR - user-generated error message
430 ; E_USER_WARNING - user-generated warning message
431 ; E_USER_NOTICE - user-generated notice message
432 ; E_DEPRECATED - warn about code that will not work in future versions
433 ; of PHP
434 ; E_USER_DEPRECATED - user-generated deprecation warnings
435 ;
436 ; Common Values:
437 ; E_ALL (Show all errors, warnings and notices including coding standards.)
438 ; E_ALL & ~E_NOTICE (Show all errors, except for notices)
439 ; E_ALL & ~E_NOTICE & ~E_STRICT (Show all errors, except for notices and coding standards warnings.)
440 ; E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR (Show only errors)
441 ; Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
442 ; Development Value: E_ALL
443 ; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT
444 ; http://php.net/error-reporting
445 ;error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT
446 error_reporting = E_ALL | E_STRICT
447
448 ; This directive controls whether or not and where PHP will output errors,
449 ; notices and warnings too. Error output is very useful during development, but
450 ; it could be very dangerous in production environments. Depending on the code
451 ; which is triggering the error, sensitive information could potentially leak
452 ; out of your application such as database usernames and passwords or worse.
453 ; For production environments, we recommend logging errors rather than
454 ; sending them to STDOUT.
455 ; Possible Values:
456 ; Off = Do not display any errors
457 ; stderr = Display errors to STDERR (affects only CGI/CLI binaries!)
458 ; On or stdout = Display errors to STDOUT
459 ; Default Value: On
460 ; Development Value: On
461 ; Production Value: Off
462 ; http://php.net/display-errors
463 display_errors = On
464
465 ; The display of errors which occur during PHP's startup sequence are handled
466 ; separately from display_errors. PHP's default behavior is to suppress those
467 ; errors from clients. Turning the display of startup errors on can be useful in
468 ; debugging configuration problems. We strongly recommend you
469 ; set this to 'off' for production servers.
470 ; Default Value: Off
471 ; Development Value: On
472 ; Production Value: Off
473 ; http://php.net/display-startup-errors
474 display_startup_errors = Off
475
476 ; Besides displaying errors, PHP can also log errors to locations such as a
477 ; server-specific log, STDERR, or a location specified by the error_log
478 ; directive found below. While errors should not be displayed on productions
479 ; servers they should still be monitored and logging is a great way to do that.
480 ; Default Value: Off
481 ; Development Value: On
482 ; Production Value: On
483 ; http://php.net/log-errors
484 log_errors = On
485
486 ; Set maximum length of log_errors. In error_log information about the source is
487 ; added. The default is 1024 and 0 allows to not apply any maximum length at all.

489 log_errors_max_len = 1024
490
491 ; Do not log repeated messages. Repeated errors must occur in same file on same
492 ; line unless ignore_repeated_source is set true.
493 ; http://php.net/ignore-repeated-errors
494 ignore_repeated_errors = Off
495
496 ; Ignore source of message when ignoring repeated messages. When this setting
497 ; is On you will not log errors with repeated messages from different files or
498 ; source lines.
499 ; http://php.net/ignore-repeated-source
500 ignore_repeated_source = Off
501
502 ; If this parameter is set to Off, then memory leaks will not be shown (on
503 ; stdout or in the log). This has only effect in a debug compile, and if
504 ; error reporting includes E_WARNING in the allowed list
505 ; http://php.net/report-memleaks
506 report_memleaks = On
507
508 ; This setting is on by default.
509 ;report_zend_debug = 0
510
511 ; Store the last error/warning message in $php_errormsg (boolean). Setting this value
512 ; to On can assist in debugging and is appropriate for development servers. It should
513 ; however be disabled on production servers.
514 ; Default Value: Off
515 ; Development Value: On
516 ; Production Value: Off
517 ; http://php.net/track-errors
518 track_errors = Off
519
520 ; Turn off normal error reporting and emit XML-RPC error XML

524 ; An XML-RPC faultCode
525 ;xmlrpc_error_number = 0
526
527 ; When PHP displays or logs an error, it has the capability of formatting the
528 ; error message as HTML for easier reading. This directive controls whether
529 ; the error message is formatted as HTML or not.
530 ; Note: This directive is hardcoded to Off for the CLI SAPI
531 ; Default Value: On
532 ; Development Value: On
533 ; Production value: On
534 ; http://php.net/html-errors
535 html_errors = On
536
537 ; If html_errors is set to On *and* docref_root is not empty, then PHP
538 ; produces clickable error messages that direct to a page describing the error
539 ; or function causing the error in detail.
540 ; You can download a copy of the PHP manual from http://php.net/docs
541 ; and change docref_root to the base URL of your local copy including the
542 ; leading '/'. You must also specify the file extension being used including
543 ; the dot. PHP's default behavior is to leave these settings empty, in which
544 ; case no links to documentation are generated.
545 ; Note: Never use this feature for production boxes.

556 ; Example:
557 ;error_prepend_string = "<span style='color: #ff0000'>"
558

564
565 ; Log errors to specified file. PHP's default behavior is to leave this value

188 ; state - the state of the process (Idle, Running, ...);
189 ; start time - the date and time the process has started;
190 ; start since - the number of seconds since the process has started;
191 ; requests - the number of requests the process has served;
192 ; request duration - the duration in µs of the requests;
193 ; request method - the request method (GET, POST, ...);
194 ; request URI - the request URI with the query string;
195 ; content length - the content length of the request (only with POST);
196 ; user - the user (PHP_AUTH_USER) (or '-' if not set);
197 ; script - the main script called (or '-' if not set);
198 ; last request cpu - the %cpu the last request consumed
199 ; it's always 0 if the process is not in Idle state
200 ; because CPU calculation is done when the request
201 ; processing has terminated;
202 ; last request memory - the max amount of memory the last request consumed
203 ; it's always 0 if the process is not in Idle state
204 ; because memory calculation is done when the request
205 ; processing has terminated;
206 ; If the process is in Idle state, then informations are related to the
207 ; last request the process has served. Otherwise informations are related to
208 ; the current request being served.
