I have made a search script in OO PHP that searches for products based on the inserted criteria, selects them and checks whether a sale is on, if it's in stock and other features.I am new to OOP so I would like to get your feedback on it and whether I am doing it correctly.The whole script works but I need to know if I'm doing OK.Many thanks.Here is my search class (class.search.php)<?phpClass Search{    public $db, $productTitle = array(), $productImage = array(), $productPrice = array(), $productStock = array(),  $productId = array(), $productSalePrice = array(), $productCount = 0;    function __construct($db_connection){        $this->db = $db_connection; //stores provided db connection in variable    }    function search($searchContent, $max){        $searchContent = %.$searchContent.%;    if ($max == 0){      $searchQuery = SELECT * FROM products WHERE title LIKE ?;    }else{      $searchQuery = SELECT * FROM products WHERE title LIKE ? LIMIT $max;    }    try{       $stmt = $this->db->prepare($searchQuery); //querys db for products that contain the query in the title       $stmt->bindParam(1, $searchContent);       $stmt->execute();    }catch(PDOException $e) {       echo $e->getMessage();    }        $result = $stmt->fetchAll(PDO::FETCH_ASSOC); //fetches results    if ($stmt->rowCount() != 0){ ///checks if there were any results      foreach ($result as $row) { //stores all info/variables in an array        $this->productCount++; //adds to the number of products        $this->productTitle[] = $row[title];        $this->productImage[] = $row[image];        $this->productPrice[] = $row[price];        $this->productSalePrice[] = $row[salePrice];        $this->productStock[] = $row['quantity'];        $this->productId[] = $row['id'];      }    }    }  function getPriceToDisplay($productSalePrice, $regularPrice){    if ($productSalePrice != 0){      return <span class='linePrice'>&pound.$regularPrice.</span> &pound.$productSalePrice;    }else{        return &pound.$regularPrice;    }  }  function getStockClass($stock){ //method to get the class for the css      if ($stock < 10){          return low_stock;      }else{          return high_stock;      }  }  function getStockStatus($stock){ //method to get the stock status for the product - a few left or in stock      if ($stock < 10 && $stock != 0){          return A few left!;      }else if ($stock == 0){        return Out of stock;      }else{           return In stock;      }  }  function searchError($error){ //method which deals with any errors that may happen    if ($error == no_results){      return No matches to your query have been found;    }else if($error == too_short){      return Your query must be at least two characters long;    }  }}?>Here is the search script (searchStore.php)<?phpinclude_once includes/header.php;require_once classes/class.db.php;require_once classes/class.search.php;if ($_SERVER[REQUEST_METHOD] == GET){    if (isset($_GET['searchContent'])){$searchContent = $_GET['searchContent'];}    if (isset($_GET['order'])){$order = $_GET['order'];}    $search = new Search($db);    $search->search($searchContent, 0);    if (strLen($searchContent) >= 2 && $search->productCount != 0){         echo <div id='searchProductsContainer'>;        for ($i = 0; $i < $search->productCount; $i++) {             $id = $search->productId[$i];            $title = $search->productTitle[$i];            $image = $search->productImage[$i];            $price = $search->productPrice[$i];            $salePrice = $search->productSalePrice[$i];            $stock = $search->productStock[$i];            echo <div class='searchProduct'><a href='item.php?item_id=.$id.'><p class='title'>.$title.</p>                    <img src='.$image.'/></a>                    <p class='price_stock'>.$search->getPriceToDisplay($salePrice, $price).<span class='.$search->getStockClass($stock).'>$search->getStockStatus($stock).</span></p>                 </div>;        }         echo </div>;    }else{        $errorMessage = array();        //checks what the error is         if ($search->productCount == 0){            $errorMessage[] = $search->searchError(no_results);        }        if(strLen($searchContent) < 2){            $errorMessage[] = $search->searchError(too_short);        }        echo <div id='searchError'>;        foreach ($errorMessage as $error){            echo <p>.$error.</p>;        }        echo </div>;    }}?>
