Prerequisites

Before we begin, make sure you have:

A web server (e.g., Apache) installed on your computer or web hosting environment.
PHP installed on your server.
A MySQL database or similar database system.

Project Structure

Here's how your project structure should look:


```
project_folder/
│── index.php
│── search.php
│── login.php
│── db_config.php
│── style.css
│── images/
│   │── product1.jpg
│   │── product2.jpg
│   │── ...
```

Step 1: Setting Up the DatabaseConnection

Establish a connection to your MySQL database by creating the `db_config.php` file:


	```php
	<!--?php
		$host = 'localhost';
		$username = 'your_username';
		$password = 'your_password';
		$database = 'your_database';
		
		$conn = new mysqli($host, $username, $password, $database);
		
		if ($conn--->connect_error) {
	die("Connection failed: " . $conn->connect_error);
	}
	?>
	```

Replace `your_username`, `your_password`, and `your_database` with your actual database credentials.

Step 2: Creating the Main Page

Develop the main page of your website using the `index.php` file:


< !--index.php -->
< !DOCTYPE html >
< html >
< head >
< title > Product Search < /title >
< link rel="stylesheet" type="text/css" href="style.css">
< /head >
< body >
< h1 > Product Search < /h1 >
< form action="search.php" method="get">
< input type="text" name="query" placeholder="Enter product name">
< button type="submit">Search< /button >
< /form >
< /body >
< /html >

Step 3: Implementing the Search Functionality

Implement the search results functionality using the `search.php` file:


	```php
	<!--search.php -->
	<!--?php
		include 'db_config.php';
		
		if (isset($_GET['query'])) {
		    $searchQuery = $_GET['query'];
		
		    $sql = "SELECT * FROM products WHERE name LIKE '%$searchQuery%'";
		    $result = $conn--->query($sql);
	}
	?>
	<- The rest of the search results display HTML -->
	```

Step 4: Styling Your Website

Enhance the visual appearance of your website with a `style.css` file:


```css
/* style.css */
/* Your CSS styling rules here */
```

Incorporate user login capabilities by creating the `login.php` file:


< !--login.php -->
< !DOCTYPE html >
< html >
< head >
< title > Login < /title >
< link rel="stylesheet" type="text/css" href="style.css">
< /head >
< body >
< h1 > Login < /h1 >
< form action="login_process.php" method="post">
< input type="text" name="username" placeholder="Username">
< input type="password" name="password" placeholder="Password">
< button type="submit">Login< /button >
< /form >
< /body >
< /html >

Create the `login_process.php` file to handle the login process:


	```php
    <!--login_process.php --gt;
	<!--?php
		session_start();
		include 'db_config.php';
		
		if ($_SERVER['REQUEST_METHOD'] === 'POST') {
		    $username = $_POST['username'];
		    $password = $_POST['password'];
		
		    $sql = "SELECT * FROM users WHERE username = '$username' AND password = '$password'";
		    $result = $conn--->query($sql);
	if ($result && $result->num_rows === 1) {
	$_SESSION['username'] = $username;
	header("Location: index.php");
	exit();
	} else {
	echo "Invalid credentials. Please try again.";
	}
	}
	?>
	```
