Recently, due to needs, I wrote a "function from Arabic numerals to Chinese numerals". After searching for the highlights, I only saw a similar one.
I feel that my algorithm is good, so I posted it and shared it. If it is used for the conversion of the amount, I need to modify the processing of the decimal part.
<?php
function ch_num($num,$mode=true) {
$char = array("zero","one","two","three","si","wu","lu","seven","ba","nine");
$dw = array("","select","billion","sen","sen");
$dec = "point";
$retval = "";
if($mode)
preg_match_all("/^0*(\d*)\.?(\d*)/",$num, $ar);
else
preg_match_all("/(\d*)\.?(\d*)/",$num, $ar);
if($ar[2][0] != "")
$retval = $dec . ch_num($ar[2][0],false); //If there is a decimal, first process the decimal recursively
if($ar[1][0] != "") {
$str = strrev($ar[1][0]);
for($i=0;$i<strlen($str);$i++) {
$out[$i] = $char[$str[$i]];
if($mode) {
$out[$i] .= $str[$i] != "0"? $dw[$i%4] : "";
if($str[$i]+$str[$i-1] == 0)
$out[$i] = "";
if($i%4 == 0)
$out[$i] .= $dw[4+floor($i/4)];
}
}
$retval = join("",array_reverse($out)) . $retval;
}
return $retval;
}
//echo ch_num("12345006789001.123");
//echo ch_num("880079.1234");
echo ch_num("300045.0123");
?>
