Налаштування під час виконання

На поведінку цих функцій випливають налаштування в php.ini.

Тут є коротке пояснення директив конфігурації.

mbstring.language string

The default national language setting (NLS) used in mbstring. Note that this option automagically defines mbstring.internal_encoding and mbstring.internal_encoding should be placed after mbstring.language in php.ini

mbstring.encoding_translation bool

Enables the transparent character encoding filter for the incoming HTTP queries, which performs detection and conversion of the input encoding to the internal character encoding.

mbstring.internal_encoding string

Увага

Цей застарілий функціонал буде обов'язково видалено у майбутньому.

Defines the default internal character encoding.

Users should leave this empty and set default_charset instead.

mbstring.http_input string

Увага

Цей застарілий функціонал буде обов'язково видалено у майбутньому.

Defines the default HTTP input character encoding.

Users should leave this empty and set default_charset instead.

mbstring.http_output string

Увага

Цей застарілий функціонал буде обов'язково видалено у майбутньому.

Defines the default HTTP output character encoding (output will be converted from the internal encoding to the HTTP output encoding upon output).

Users should leave this empty and set default_charset instead.

mbstring.detect_order string

Defines default character code detection order. See also mb_detect_order().

mbstring.substitute_character string

Defines character to substitute for invalid character encoding. See mb_substitute_character() for supported values.

mbstring.func_overload string

Увага

Цей функціонал ЗАСТАРІВ, починаючи з PHP 7.2.0, та ВИЛУЧЕНИЙ в PHP 8.0.0. Вкрай не рекомендується на нього покладатися.

Overloads a set of single byte functions by the mbstring counterparts. See Function overloading for more information.

This setting can only be changed from the php.ini file.

mbstring.http_output_conv_mimetypes string

mbstring.strict_detection bool

Enables strict encoding detection. See mb_detect_encoding() for a description and examples.

mbstring.regex_retry_limit int

Limits the amount of backtracking that may be performed during one mbregex match.

This setting only takes effect when linking against oniguruma >= 6.8.0.

mbstring.regex_stack_limit int

Limits the stack depth of mbstring regular expressions.

According to the » HTML 4.01 specification, Web browsers are allowed to encode a form being submitted with a character encoding different from the one used for the page. See mb_http_input() to detect character encoding used by browsers.

Although popular browsers are capable of giving a reasonably accurate guess to the character encoding of a given HTML document, it would be better to set the charset parameter in the Content-Type HTTP header to the appropriate value by header() or default_charset ini setting.
