从http.post（）获取十进制数

Question

我在我的控制器中有功能，将值发布到php，当使用http.post（）发布十进制值时，php将其作为一个圆值。如何将十进制值接收到php变量中。

update.js

$scope.updatemyinterest=function(){ 
        $http.post("php/updateMYINTEREST.php",{'INTR1':$scope.intr1,    
                                               'INTR2':$scope.intr2,
                                               'AMNTPERGRAM':$scope.intrstamnt
                                             })     
            console.log($scope.intrstamnt)//2521
            console.log($scope.intr1)//2.5
            console.log($scope.intr2)//2.33
               }

update.php

<?php
include "connectdb.php";
$data=json_decode(file_get_contents("php://input"));
$INTR1=$dbhandle->real_escape_string($data->INTR1);
$INTR2=$dbhandle->real_escape_string($data->INTR2);
$AMNTPERGRAM=$dbhandle->real_escape_string($data->AMNTPERGRAM);
$query1="UPDATE myinterest SET  INTR1='$INTR1',INTR2='$INTR2',AMNTPERGRAM='$AMNTPERGRAM' ";
$dbhandle->query($query1);
