<function>mb_convert_case</function> returns case folded version of
|
|
<parameter>string</parameter> converted in the way specified by
|
|
<parameter>mode</parameter>.
|
|
</para>
|
|
<para>
|
|
<parameter>mode</parameter> can be one of MB_CASE_UPPER, MB_CASE_LOWER
|
|
or MB_CASE_TITLE.

</para>

<para>
|
|
<parameter>encoding</parameter> specifies the encoding of
|
|
<parameter>str</parameter>; if omitted, the internal character encoding

value will be used.

</para>

|
<para>
|
|
The return value is str with the appropriate case folding applied.

</para>
|
|
<para>
|
|
By contrast to the standard case folding functions such as
|
|
<function>strtolower</function> and <function>strtoupper</function>,
|
|
case folding is performed on the basis of the Unicode character
|
|
properties. Thus the behaviour of this function is not affected
|
|
by locale settings and it can convert any characters that have
|
|
'alphabetic' property, such as A-umlaut (Ä).
|
|
</para>
|
|
<para>
|
|
