- (Created missing setup sections in setup.xml, if any) - Moved the intro to book.xml - Changed the intro ID from <extname>.intro to intro.<extname> - Moved the constants entity to book.xml - Changed constants.xml to be an appendix - Moved the mbstring.php4.req into its own chapter (encoding-requirements.xml) - Changed mbstring.encodings to be an chapter (encodings.xml) - Moved the mbstring.http section into its own chapter (http-inout.xml) - Moved the mbstring.ja-basic into its own chapter (ja-basic.xml) - Moved mbstring.overload into its own chapter (overloading.xml) - Moved mbstring.supported-encodings into its own chapter (supported-encodings.xml) - Moved the configure & ini entities to setup.xml NOTE: There is still a partintro in refernce.xml git-svn-id: https://svn.php.net/repository/phpdoc/en/trunk@248994 c90b9560-bf6c-de11-be94-00142212c4b1

|
|
While there are many languages in which every necessary character can
|
|
be represented by a one-to-one mapping to an 8-bit value, there are also
|
|
several languages which require so many characters for written
|
|
communication that they cannot be contained within the range a mere byte
|
|
can code (A byte is made up of eight bits. Each bit can contain only two
|
|
distinct values, one or zero. Because of this, a byte can only represent
|
|
256 unique values (two to the power of eight)). Multibyte character
|
|
encoding schemes were developed to express more than 256 characters
|
|
in the regular bytewise coding system.
|
|
</para>

<para>
|
|
When you manipulate (trim, split, splice, etc.) strings encoded in a
|
|
multibyte encoding, you need to use special functions since two or more
|
|
consecutive bytes may represent a single character in such encoding
|
|
schemes. Otherwise, if you apply a non-multibyte-aware string function
|
|
to the string, it probably fails to detect the beginning or ending of
|
|
the multibyte character and ends up with a corrupted garbage string that
|
|
most likely loses its original meaning.

|
|
<para>
|
|
<literal>mbstring</literal> provides multibyte specific string functions
|
|
that help you deal with multibyte encodings in PHP. In addition to that,
|
|
<literal>mbstring</literal> handles character encoding conversion between
|
|
the possible encoding pairs. <literal>mbstring</literal> is designed to
|
|
handle Unicode-based encodings such as UTF-8 and UCS-2 and many
|
|
single-byte encodings for convenience (listed below).
