Arabic numeral font implements a function to convert Arabic numerals to Chinese numerals under PHP

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"," "二","三","四","五","鲁","七","八","九");
$dw = array("","十","百","仟","","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");
?>
