php获取汉字拼音的第一个字母
复制代码 代码如下:
function getinitial($str)
{
$asc=ord(substr($str,0,1));
if ($asc{
if ($asc>=48 && $ascreturn '1'; //数字
}elseif ($asc>=65 && $ascreturn chr($asc); // A--Z
}elseif ($asc>=97 && $ascreturn chr($asc-32); // a--z
}else{
return '~'; //其他
}
}
else //中文
{
$asc=$asc*1000+ord(substr($str,1,1));
//获取拼音首字母A--Z
if ($asc>=176161 && $ascreturn 'A';
