一些比較正式的系統，對於數字很敏感，除了要有逗號(使用內建number_format函數)分隔格式之外，需要大寫國字，比如說10000，需要寫成10,000，或者寫成壹萬，尤其在會計帳務、請款單、收據、發票、報表...，很多地方都會要求有這樣功能，以下我們就來教學一下，PHP到底怎麼實現呢？
程式碼如下：
<?php
function num2cht($num){
$numc ="零,壹,貳,參,肆,伍,陸,柒,捌,玖";
$unic = ",拾,佰,仟";
$unic1 = "元整,萬,億,兆,京";
$numc_arr = split(",", $numc);
$unic_arr = split(",", $unic);
$unic1_arr = split(",", $unic1);
$i = str_replace(",", "", $num);
$c0 = 0;
$str = array();
do{
$aa = 0;
$c1 = 0;
$s = "";
$lan = (strlen($i) >= 4) ? 4 : strlen($i);
$j = substr($i, -$lan);
while($j > 0){
$k = $j % 10;
if($k > 0) {
$aa = 1;
$s = $numc_arr[$k].$unic_arr[$c1].$s;
}elseif($k == 0) {
if($aa == 1) $s = "0".$s;
}
$j = intval($j / 10);
$c1 += 1;
}
$str[$c0] = ($s == '') ? '' : $s.$unic1_arr[$c0];
$count_len = strlen($i) - 4;
$i = ($count_len > 0) ? substr($i, 0, $count_len) : '';
$c0 += 1;
}while($i != '');
foreach($str as $v) $string .= array_pop($str);
$string = preg_replace('/0+/', '零', $string);
return $string;
}
?>
|
使用方法：
<?php $a = 123456789; $b = 123456; $c = 1500; echo $a." = ".num2cht($a)."\n"; echo $b." = ".num2cht($b)."\n"; echo $c." = ".num2cht($c)."\n"; ?> |
執行結果：
123456789 = 壹億貳仟參佰肆拾伍萬陸仟柒佰捌拾玖元整 123456 = 壹拾貳萬參仟肆佰伍拾陸元整 1500 = 壹仟伍佰元整 |
