Тут є коротке пояснення директив
конфігурації.
-
error_reporting
int
-
Set the error reporting level. The parameter is either an integer
representing a bit field, or named constants. The error_reporting
levels and constants are described in
Predefined Constants,
and in php.ini. To set at runtime, use the
error_reporting() function. See also the
display_errors directive.
The default value is E_ALL.
Prior to PHP 8.0.0, the default value was:
E_ALL &
~E_NOTICE &
~E_STRICT &
~E_DEPRECATEDE_NOTICE,
E_STRICT and E_DEPRECATED
were not shown.
Зауваження:
PHP Constants outside of PHP
Using PHP Constants outside of PHP, like in httpd.conf,
will have no useful meaning so in such cases the int values
are required. And since error levels will be added over time, the maximum
value (for E_ALL) will likely change. So in place of
E_ALL consider using a larger value to cover all bit
fields from now and well into the future, a numeric value like
2147483647 (includes all errors, not just
E_ALL).
-
display_errors
string
-
This determines whether errors should be printed to the screen
as part of the output or if they should be hidden from the user.
Value "stderr" sends the errors to stderr
instead of stdout.
Зауваження:
This is a feature to support your development and should never be used
on production systems (e.g. systems connected to the internet).
Зауваження:
Although display_errors may be set at runtime (with ini_set()),
it won't have any effect if the script has fatal errors.
This is because the desired runtime action does not get executed.
-
display_startup_errors
bool
-
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 debugging.
-
log_errors
bool
-
Tells whether script error messages should be logged to the
server's error log or error_log.
This option is thus server-specific.
Зауваження:
You're strongly advised to use error logging in place of
error displaying on production web sites.
-
log_errors_max_len
int
-
Set the maximum length of log_errors in bytes. In
error_log information about
the source is added. The default is 1024 and 0 allows to not apply
any maximum length at all.
This length is applied to logged errors, displayed errors and also to
$php_errormsg, but not to explicitly called functions
such as error_log().
Коли використовується
int, значення вимірюється в байтах. Також можна робити скорочений
запис, як це описано в цих
ЧаПах.
-
ignore_repeated_errors
bool
-
Do not log repeated messages. Repeated errors must occur in the same
file on the same line unless
ignore_repeated_source
is set true.
-
ignore_repeated_source
bool
-
Ignore source of message when ignoring repeated messages. When this setting
is On you will not log errors with repeated messages from different files or
sourcelines.
-
report_memleaks
bool
-
If this parameter is set to On (the default), this parameter will show a
report of memory leaks detected by the Zend memory manager. This report
will be sent to stderr on Posix platforms. On Windows, it will be sent
to the debugger using OutputDebugString() and can be viewed with tools
like » DbgView.
This parameter only has effect in a debug build and if
error_reporting includes E_WARNING in the allowed
list.
-
track_errors
bool
-
If enabled, the last error message will always be present in the
variable $php_errormsg.
-
html_errors
bool
-
If enabled, error messages will include HTML tags. The format for HTML
errors produces clickable messages that direct the user to a page
describing the error or function in causing the error. These references
are affected by
docref_root and
docref_ext.
If disabled, error message will be solely plain text.
-
xmlrpc_errors
bool
-
If enabled, turns off normal error reporting and formats errors as
XML-RPC error message.
-
xmlrpc_error_number
int
-
Used as the value of the XML-RPC faultCode element.
-
docref_root
string
-
The new error format contains a reference to a page describing the error or
function causing the error. In case of manual pages you can download the
manual in your language and set this ini directive to the URL of your local
copy. If your local copy of the manual can be reached by "/manual/"
you can simply use docref_root=/manual/. Additional you have
to set docref_ext to match the fileextensions of your copy
docref_ext=.html. It is possible to use external
references. For example you can use
docref_root=http://manual/en/ or
docref_root="http://landonize.it/?how=url&theme=classic&filter=Landon
&url=http%3A%2F%2Fwww.php.net%2F"
Most of the time you want the docref_root value to end with a slash "/".
But see the second example above which does not have nor need it.
Зауваження:
This is a feature to support your development since it makes it easy to
lookup a function description. However it should never be used on
production systems (e.g. systems connected to the internet).
-
docref_ext
string
-
See docref_root.
Зауваження:
The value of docref_ext must begin with a dot ".".
-
error_prepend_string
string
-
String to output before an error message.
Only used when the error message is displayed on screen. The main purpose
is to be able to prepend additional HTML markup to the error message.
-
error_append_string
string
-
String to output after an error message.
Only used when the error message is displayed on screen. The main purpose
is to be able to append additional HTML markup to the error message.
-
error_log
string
-
Name of the file where script errors should be logged. The file should
be writable by the web server's user. If the
special value syslog is used, the errors
are sent to the system logger instead. On Unix, this means
syslog(3) and on Windows it means the event log. See also:
syslog().
If this directive is not set, errors are sent to the SAPI error logger.
For example, it is an error log in Apache or stderr
in CLI.
See also error_log().
-
error_log_mode
int
-
File mode for the file described set in
error_log.
-
syslog.facility
string
-
Specifies what type of program is logging the message.
Only effective if error_log is set to "syslog".
-
syslog.filter
string
-
Specifies the filter type to filter the logged messages. Allowed
characters are passed unmodified; all others are written in their
hexadecimal representation prefixed with \x.
-
all – the logged string will be split
at newline characters, and all characters are passed unaltered
-
ascii – the logged string will be split
at newline characters, and any non-printable 7-bit ASCII characters will be escaped
-
no-ctrl – the logged string will be split
at newline characters, and any non-printable characters will be escaped
-
raw – all characters are passed to the system
logger unaltered, without splitting at newlines (identical to PHP before 7.3)
This setting will affect logging via error_log set to "syslog" and calls to syslog().
Зауваження:
The raw filter type is available as of PHP 7.3.8 and PHP 7.4.0.
This directive is not supported on Windows.
-
syslog.ident
string
-
Specifies the ident string which is prepended to every message.
Only effective if error_log is set to "syslog".
