    {
        if(isset($_POST['mobilenumber'])) {
    //$modelArray = Customers::find()->where(['cust_mobile' => $_POST['mobilenumber']])->one();
$connection = \Yii::$app->getDb();

$command = $connection->createCommand(
  "SELECT * ".
  "FROM customers AS C ".
  "WHERE C.cust_mobile= " .$_POST['mobilenumber']
           // "AND C.cust_mobile=" .$_POST['mobilenumber2']
  );    
$modelArray = $command->queryAll();

if(count($modelArray) > 0) {

print_r(json_encode($modelArray));
                /*Here I wanna set data which is comming from response i.e in object($modelArray)
                on same form i.e is like a update form i.e here update logic i want to apply*/
            } else {

                    <?= $form->field($modelCustomersSender, 'cust_lname')->textInput(['maxlength' => true]) ?>

Answer 1

in your code there are a number of non-recommended practices. for example the fact to directly access the $ _POST instead of creating a suitable model and load the values with model-> load or the failure to use the rendering of views to make a ajax action for Update Your data .. in any case the discussion for every aspect would be too long so I give you the code available in the way that I think is closer to the way you write.

You action create could be somethings like this

public function actionCreate()
{
    if(isset($_POST['mobilenumber'])) {
        $modelArray = Customers::find()->where(['cust_mobile' => $_POST['mobilenumber']])->one();
        /*Here I got object in which whatever mobile number we enter 
        in text box. as per mobile number i got result and I check a condition is, if result count grater than 0 then 
        form open with fill text field else open with empty field  */
        if(count($modelArray) > 0) {
             $
            /*Here I wanna set data which is comming from response i.e in object($modelArray)
            on same form i.e is like a update form i.e here update logic i want to apply*/
            $modelArray->attribute1 = $_POST['your_attribute1'];
             ......
             $newModel->attributeN = $_POST['your_attributeN'];
             $newModel->save()  
             // redirect or render what you prefer 
             return $this->redirect(['the_view_you_prefer']);              

        } else {
            /*Here new record is create if enter mobile number is not exist*/
             $newModel = new Customers();
             $newModel->mobilenumber =  $_POST['mobilenumber']
             $newModel->attribute1 = $_POST['your_attribute1'];
             ......
             $newModel->attributeN = $_POST['your_attributeN'];
             $newModel->save()
            return $this->redirect(['the_view_you_prefer']);
        }

    } else {
/*open form if mobile number not set*/
    }
}

Otherwise if you only want render the value for ajax you can

 myArray['your_attribute1'] = $_POST['your_attribute1'];
 ....
 myArray['your_attributeN'] = $_POST['your_attributeN'];

 $arrayToAjax= json_encode($myArray);
 echo  $arrayToAjax; 

This should return the json formatted result for your ajax success function

for retrive the data in success function you can use jsonParse

  success: function(data){
         alert(data);//response display here

         var jsonData = JSON.parse(data);
         alert(jsonData[0].cust_fname);
         alert(jsonData[0].cust_lname);

       $('customers-cust_lname').val(data);//how to set value fot that text field from response
        // window.location.reload(true);
       }
