Answer: To convert amount in crores to decimal value in php, here's the code:

<?php
// Create a function for converting the amount to decimal
function convertCrtoDecimal($amount) {
     $Arraycheck = array("4"=>"K","5"=>"K","6"=>"Lacs","7"=>"Lacs","8"=>"Cr","9"=>"Cr");
     // define decimal values
     $numberLength = strlen($amount); //count the length of numbers
     if ($numberLength > 3) {
        foreach ($Arraycheck as $Lengthnum=>$unitval) {
            if ($numberLength == $Lengthnum) {
               if ($Lengthnum % 2 == 0) {
                  $RanNumber = substr($amount,1,2);
                  $NmckGtZer = ($RanNumber[0]+$RanNumber[1]);
                  if ($NmckGtZer < 1) { 
                      $RanNumber = "0";
                  } else {
                     if ($RanNumber[1] == 0) {
                        $RanNumber[1] = "0";
                  } 
             }
      $amount = substr($amount,0,$numberLength-$Lengthnum+1) . "." . $RanNumber . " $unitval ";
    } else {
         $RanNumber = substr($amount,2,2);
         $NmckGtZer = ($RanNumber[0]+$RanNumber[1]);
         if ($NmckGtZer < 1) { 
            $RanNumber  = 0;
        } else {
            if ($RanNumber[1] == 0)  {
                $RanNumber[1] = "0";
            }   
        }
         $amount = substr($amount,0,$numberLength-$Lengthnum+2) . ".". $RanNumber . " $unitval";   
       }
     }
 }
 } else {
     $amount . "Rs";    
 }
 return $amount;
 }
 
 ?>

<!-- Call the function here -->

<?php $amount=455000; //nummeric value in variable
 
$get_amount= convertCrtoDecimal($amount);
echo 'Rs '.$get_amount;

?>

Output: Rs 4.55 Lacs
