Breve descrizione dei parametri di configurazione.

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

Avviso

Questa funzione deprecata sarà sicuramente rimossa in futuro.

Defines the default internal character encoding.

Users should leave this empty and set default_charset instead.

mbstring.http_input string

Avviso

Questa funzione deprecata sarà sicuramente rimossa in futuro.

Defines the default HTTP input character encoding.

Users should leave this empty and set default_charset instead.

mbstring.http_output string

Avviso

Questa funzione deprecata sarà sicuramente rimossa in futuro.

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

Avviso

This feature has been DEPRECATED as of PHP 7.2.0, and REMOVED as of PHP 8.0.0. Relying on this feature is highly discouraged.

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.
