PHP 数字转换中文

------------恢复内容开始------------

1.在最近的开发需求因为要用到类似支付宝或者微信收款声音模拟，要将金额改为中文，所以做一下处理

2.思路是已小数点为区分，比如是0.45元就是零点四五元，具体如下，如有优化的希望大佬指点：

$num = '153.2';//"一百五十三点二
function cc($num){
    if(strpos($num,'.') !== false)//如果是小数点显示  "一百五十三点二
    {
        $number = explode('.',$num);
        $num1 =  num2cn($number[0]);
        $num2 = '';
        $num_float = str_split($number[1], 1);
        foreach ($num_float as $key => &$value) {
            $num2 .= num2cn($value);
        }
        dd($num1.'点'.$num2);
    }else{
        dd(num2cn($num));
    }   
}

function num2cn($number) {
    $number = intval ( $number );
    $capnum = array ( "零", "一","二","三", "四", "五", "六", "七","八","九" );
    $capdigit = array ( "", "十","百","千","万");
    $data_arr = str_split ( $number );
    $count = count ( $data_arr );
    for($i = 0; $i < $count; $i ++) {
        $d = $capnum [$data_arr [$i]];
        $arr [] = $d != '零' ? $d . $capdigit [$count - $i - 1] : $d;
    }
    $cncap = implode ( "", $arr );
    $cncap = preg_replace ( "/(零)+/", "0", $cncap ); // 合并连续“零”
    $cncap = trim ( $cncap, '0' );
    $cncap = str_replace ( "0", "零", $cncap ); // 合并连续“零”
    $cncap == '一十' && $cncap = '十';
    $cncap == '' && $cncap = '零';
    return $cncap;
}
