PHP - 使用mb_get_info()获取mbstring的内部设置

The mb_get_info() function in PHP is used to get the internal settings of mbstring. This function is supported in PHP 5.4 or higher version.

Syntax

array|string|int mb_get_info(str $type = "all")

Parameters

It accepts only a single parameter to get the multibyte information.

$type − If the type parameter is not specified or it is specified as "all", then it will return the following information −

"internal_encoding", "http_input", "http_output", "http_output_conv_mimetypes", "mail_charset", "mail_header_encoding", "mail_body_encoding", "illegal_chars", "encoding_translation", "language", "detect_order", "substitute_character", "strict_detection"

If the type parameter is specified as any of the following −

"internal_encoding", "http_input", "http_output", "http_output_conv_mimetypes", "mail_charset", "mail_header_encoding", "mail_body_encoding", "illegal_chars", "encoding_translation", "language", "detect_order", "substitute_character" or "strict_detection",

然后它将返回指定的设置参数。

返回值

mb_get_info()如果未指定type，则返回type信息的数组，否则返回特定的类型。失败时返回false。

注意 − 从PHP 8.0.0开始，不支持"func_overload"和"func_overload_list"类型。
