php格式化金额函数分享,php金额函数

最近的项目在处理资金这一块的功能,对人民币金额的格式化输出是必不可少的功能。这个功能比较独立而且还比较大众化,所以封装成了函数就发上去也算是方便大家。

复制代码 代码如下:


/**
 * 格式化金额
 *
 * @param int $money
 * @param int $len
 * @param string $sign
 * @return string
 */
function format_money($money, $len=2, $sign='¥'){
    $negative = $money > 0 ? '' : '-';
    $int_money = intval(abs($money));
    $len = intval(abs($len));
    $decimal = '';//小数
    if ($len > 0) {
        $decimal = '.'.substr(sprintf('%01.'.$len.'f', $money),-$len);
    }
    $tmp_money = strrev($int_money);
    $strlen = strlen($tmp_money);
    for ($i = 3; $i         $format_money .= substr($tmp_money,0,3).',';
        $tmp_money = substr($tmp_money,3);
    }
    $format_money .= $tmp_money;
    $format_money = strrev($format_money);
    return $sign.$negative.$format_money.$decimal;
}

以上就是本文的全部内容,希望大家能够喜欢。
