you have missed $ in last condition.

<?php   $email = $_post['email'];   $p_name = $_post['p_name'];   $noc = $_post['noc'];   $year = $_post['year'];     $get_email = "select email book email = '$email' ";   $run_email = mysqli_query($con,$get_email);   $check = mysqli_num_rows($run_email);    if($check==1){      echo "<script>alert('you have booked') </script>";     exit();   }      $get_name = "select capacity party type_party='$p_name' ";     $run_name = mysqli_query($con,$get_name);     $checkname = mysqli_num_rows($run_name );     //$checkk = $run_name > '$noc';    if($checkname > $noc){      echo "<script>alert('out of bound') </script>";     exit();     } ?>
