PHP-Codebeispiel zur Konvertierung von Betragszahlen ins Englische

Ich habe schon lange danach gesucht, aber die Suche nach Schlüsselwörtern scheint immer unbefriedigend zu sein.

Der Code lautet wie folgt:

<?php 
$num=1220.01; 
echo fmoney($num);//结果：1,220.21 
echo umoney($num); 
//结果：ONE THOUSAND AND TWO HUNDRED TWENTY DOLLARS AND TWENTY-ONE CENTS ONLY 
echo umoney($num,"rmb"); 
//结果：ONE THOUSAND AND TWO HUNDRED TWENTY YUAN AND TWENTY-ONE FEN ONLY 
//define 
//格式化货币 
function fmoney($num) { 
$num=0+$num; 
$num = 
sprintf
("%.02f",$num); 
if(strlen($num) <= 6) 
return
 $num; 
//从最后开始算起，每3个数它加一个"," 
for($i=strlen($num)-1,$k=1, $j=100; $i >= 0; $i--,$k++) { 
$one_num = substr($num,$i,1); 
if($one_num ==".") { 
$numArray[$j--] = $one_num; 
$k=0; 
continue
; 
} 
if($k%3==0 and $i!=0) { 
//如果正好只剩下3个数字，则不加&#39;,&#39; 
$numArray[$j--] = $one_num; 
$numArray[$j--] = ","; 
$k=0; 
} else { 
$numArray[$j--]=$one_num; 
} 
} 
ksort($numArray); 
return join("",$numArray);
