例如$num =’7,57,800′;

如何将$number的值显示为7.57 Lakhs？

解决方法:

这是功能：

function formatInIndianStyle($num){
     $pos = strpos((string)$num, ".");
     if ($pos === false) {
        $decimalpart="00";
     }
     if (!($pos === false)) {
        $decimalpart= substr($num, $pos+1, 2); $num = substr($num,0,$pos);
     }

     if(strlen($num)>3 & strlen($num) <= 12){
         $last3digits = substr($num, -3 );
         $numexceptlastdigits = substr($num, 0, -3 );
         $formatted = makeComma($numexceptlastdigits);
         $stringtoreturn = $formatted.",".$last3digits.".".$decimalpart ;
     }elseif(strlen($num)<=3){
        $stringtoreturn = $num.".".$decimalpart ;
     }elseif(strlen($num)>12){
        $stringtoreturn = number_format($num, 2);
     }

     if(substr($stringtoreturn,0,2)=="-,"){
        $stringtoreturn = "-".substr($stringtoreturn,2 );
     }

     return $stringtoreturn;
 }

 function makeComma($input){ 
     if(strlen($input)<=2)
     { return $input; }
     $length=substr($input,0,strlen($input)-2);
     $formatted_input = makeComma($length).",".substr($input,-2);
     return $formatted_input;
 }
