Implement a function to convert Arabic numerals to Chinese numerals under PHP_PHP Tutorial

If you want to use it for the conversion of amounts, you need to modify the processing of the decimal part

function ch_num($num,$mode=true) {
$char = array( "zero", "one", "two", "three", "four", "five", "Lu", "旒", "eight", "玖");
$dw = array(" ","十","百","千","","万","Billion"," trillion");
$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 are decimals, process the decimals recursively first
if($ar[1][0] != "") {
$str = strrev($ar[1][0]);
for($i=0;$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");
