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_DEPRECATED. This means diagnostics of level E_NOTICE, E_STRICT and E_DEPRECATED were not shown. 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. This is a feature to support your development and should never be used on production systems (e.g. systems connected to the internet). 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. 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. &ini.shorthandbytes; 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. 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. 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. 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".
