早些年做CRM用到的一个金额转换函数，今天从旧项目中拿出来记录一下。金额转换的函数方法有很多，都很不错。不过这个是小崔刚工作的时候写的一个转换函数，多少还是有点纪念意义。如有问题请朋友们指出，小崔及时修正。谢谢啦！
废话不多说直接上代码：
1 <?php 2 ?3 /** 4 * 数字金额转换大写数字 5 * $num 数字类型 6 */ 7 ?8 function inttodaxie($num) { 9 ????//判断$num是否数字10 ????if(!is_numeric($num)) return -1;11 ????$dint = array(‘零‘, ‘壹‘, ‘贰‘, ‘叁‘, ‘肆‘, ‘伍‘, ‘陆‘, ‘柒‘, ‘捌‘, ‘玖‘);12 ????$len = strlen($num);13 ????$dstr = ‘‘;14 ????for($i = 0; $i <= $len; $i++) {15 ????????$key_ = substr($num, $i, 1);16 ????????$dstr .= $dint[$key_];17 ????}18 ????return $dstr;19 }20 21 $result = inttodaxie(90011234);22 var_dump($result);23 echo ‘<br>‘;以上是基础转换代码，在这个基础上进行二次改造：
1 <?php 2 ?3 /** 4 * 转换大写金额 5 * $num 数字类型 6 */ 7 ?8 function inttod($num) { 9 ????//判断$num是否存在10 ????if(!$num) return ‘零圆‘;11 ????//保留小数点后两位12 ????$num = round($num, 2);13 ????//将浮点转换为整数14 ????$tem_num = $num * 100;15 ????//判断数字长度16 ????$tem_num_len = strlen($tem_num);17 ????if($tem_num_len > 14) {18 ????????return ‘数字太大了吧，有这么大的金钱吗‘;19 ????}20 21 ????//大写数字22 ????$dint = array(‘零‘, ‘壹‘, ‘贰‘, ‘叁‘, ‘肆‘, ‘伍‘, ‘陆‘, ‘柒‘, ‘捌‘, ‘玖‘);23 ????//大写金额单位24 ????$danwei = array(‘仟‘, ‘佰‘, ‘拾‘, ‘亿‘, ‘仟‘, ‘佰‘, ‘拾‘, ‘万‘, ‘仟‘, ‘佰‘, ‘拾‘, ‘圆‘);25 ????$danwei1 = array(‘角‘, ‘分‘);26 27 ????//空的变量用来保存转换字符串28 ????$daxie = ‘‘;29 30 ????//分割数字，区分圆角分31 ????list($left_num, $right_num) = explode(‘.‘, $num);32 33 ????//计算单位长度34 ????$danwei_len = count($danwei);35 ????//计算分割后的字符串长度36 ????$left_num_len = strlen($left_num);37 ????$right_num_len = strlen($right_num);38 39 ????//循环计算亿万元等40 ????for($i = 0; $i < $left_num_len; $i++) {41 ????????//循环单个文字42 ????????$key_ = substr($left_num, $i, 1);43 44 ????????//判断数字不等于0或数字等于0与金额单位为亿、万、圆，就返回完整单位的字符串45 ????????if($key_ !== ‘0‘ || ($key_ == ‘0‘ && ($danwei[$danwei_len - $left_num_len + $i] == ‘亿‘ || $danwei[$danwei_len - $left_num_len + $i] == ‘万‘ || $danwei[$danwei_len - $left_num_len + $i] == ‘圆‘))) {46 ????????????$daxie = $daxie . $dint[$key_] . $danwei[$danwei_len - $left_num_len + $i];47 ????????} else {48 ????????????//否则就不含单位49 ????????????$daxie = $daxie . $dint[$key_];50 ????????}51 ????}52 53 ????//循环计算角分54 ????for($i = 0; $i < $right_num_len; $i++) {55 ????????$key_ = substr($right_num, $i, 1);56 ????????if($key_ > 0) {57 ????????????$daxie = $daxie . $dint[$key_] . $danwei1[$i];58 ????????}59 ????}60 61 ????//计算转换后的长度62 ????$daxie_len = strlen($daxie);63 ????//设置文字切片从0开始，utf-8汉字占3个字符64 ????$j = 0;65 ????while($daxie_len > 0) {66 ????????//每次切片两个汉字67 ????????$str = substr($daxie, $j, 6);68 ????????//判断切片后的文字不等于零万、零圆、零亿、零零69 ????????if($str == ‘零万‘ || $str == ‘零圆‘ || $str == ‘零亿‘ || $str == ‘零零‘) {70 ????????????//重新切片71 ????????????$left = substr($daxie, 0, $j);72 ????????????$right = substr($daxie, $j + 3);73 ????????????$daxie = $left . $right;74 ????????}75 ????????$j += 3;76 ????????$daxie_len -= 3;77 ????}78 ????79 ????return ‘人民币‘ . $daxie . ‘整‘;80 }81 82 $result = inttod(99090909090.19);83 var_dump($result);运行结果：
