The code is as follows:


Function getinitial ($ str)
{
$ Asc = ord (substr ($ str, 0, 1 ));
If ($ asc <160) // non-Chinese

Return chr ($ asc-32); // a -- z
} Else {
Return '~ '; // Others
}
}
Else // Chinese
{
$ Asc = $ asc * 1000 + ord (substr ($ str, 1, 1 ));
// Get the first letter A--Z of pinyin
