在php中创建一个循环或数组,用于比较来自不同页面的多个会话

I have multiple pages and each page has multiple radio buttons which pass values and after checking different selections across all radio buttons output a unique result currently I am creating too many if conditions which is difficult to main, can an array or loop be done for it.

<?php
            if(isset($_POST['material'])) {
              $_SESSION['material'] = $_POST['material'];

              // for screw
              if($_SESSION['category'] == "Screw" ) {
                if($_SESSION['headtype'] == "Counter Sink Philips") {
                  if($_SESSION['diameter'] == "6 MM"){
                    if($_SESSION['length'] == "10 MM"){
                      if($_SESSION['pitch'] == "1 MM") {
                        if($_SESSION['material'] == "Brass") {
                          echo "kenenth start with database";
                        }
                      }
                    }
                  }
                }
              }


              // for self tapping
              if($_SESSION['category'] == "Self Tapping" ) {
                if($_SESSION['headtype'] == "Counter Sink Philips") {
                  if($_SESSION['diameter'] == "6 MM"){
                    if($_SESSION['length'] == "10 MM"){
                      if($_SESSION['pitch'] == "1 MM") {
                        if($_SESSION['material'] == "Brass") {
                          echo "Self Tapping";
                        }
                      }
                    }
                  }
                }
              }

              // for stud
              if($_SESSION['category'] == "Stud" ) {
                if($_SESSION['headtype'] == "Counter Sink Philips") {
                  if($_SESSION['diameter'] == "6 MM"){
                    if($_SESSION['length'] == "10 MM"){
                      if($_SESSION['pitch'] == "1 MM") {
                        if($_SESSION['material'] == "Brass") {
                          echo "Stud";
                        }
                      }
                    }
                  }
                }
              }

            }
           ?>

    You could write a recursive function to do that for you:

    function in_array_r($find, $yourArray, $strict = false) {
        foreach ($yourArray as $item) {
            if (($strict ? $item === $find : $item == $find) || (is_array($item) && in_array_r($find, $item, $strict))) {
                return true;
            }
        }
    
        return false;
    }
    

    usage

    $a['category'] = array("Screw", "Self Tapping", "Stud");
    $a['headtype'] = array("Counter Sink Philips", "Counter Sink Philips"));
    echo in_array_r($_SESSION['category'], $a) ? 'found' : 'not found';
