Creating a simple Student Management System using PHP and HTML involves several components including a database to store the student records, PHP scripts to handle server-side logic, and HTML to provide the user interface. Below is a basic implementation of the requested functionalities: adding, editing, deleting, and viewing all students' information.
### Prerequisites
- **PHP** and **MySQL** installed on your server (e.g., XAMPP, WAMP, or a live server).
- An IDE or text editor for coding.
- Basic knowledge of PHP and HTML.
### Step 1: Database Setup
1. **Create the Database**:
```sql
CREATE DATABASE student_management;
USE student_management;
CREATE TABLE students (
id INT(11) AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(100) NOT NULL,
email VARCHAR(100) NOT NULL,
phone VARCHAR(15) NOT NULL,
created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);
```
### Step 2: Project Structure
- Create a folder for your project (e.g., `student_management_system`).
- Inside the folder, create the following files:
- `index.php`
- `add.php`
- `edit.php`
- `delete.php`
- `config.php`
### Step 3: Configuration File (config.php)
```php
<?php
$host = 'localhost';
$db_name = 'student_management';
$username = 'root';
$password = '';
try {
$conn = new PDO("mysql:host=$host;dbname=$db_name", $username, $password);
$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
echo "Connection failed: " . $e->getMessage();
}
?>
```
### Step 4: Index File (index.php)
```php
<?php
include 'config.php';
$stmt = $conn->prepare("SELECT * FROM students");
$stmt->execute();
$students = $stmt->fetchAll();
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Student Management System</title>
</head>
<body>
<h1>Student Management System</h1>
<a href="add.php">Add Student</a>
<table border="1">
<tr>
<th>ID</th>
<th>Name</th>
<th>Email</th>
<th>Phone</th>
<th>Actions</th>
</tr>
<?php foreach($students as $student): ?>
<tr>
<td><?php echo $student['id']; ?></td>
<td><?php echo $student['name']; ?></td>
<td><?php echo $student['email']; ?></td>
<td><?php echo $student['phone']; ?></td>
<td>
<a href="edit.php?id=<?php echo $student['id']; ?>">Edit</a>
<a href="delete.php?id=<?php echo $student['id']; ?>">Delete</a>
</td>
</tr>
<?php endforeach; ?>
</table>
</body>
</html>
```
### Step 5: Add Student (add.php)
```php
<?php
include 'config.php';
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$stmt = $conn->prepare("INSERT INTO students (name, email, phone) VALUES (?, ?, ?)");
$stmt->execute([$name, $email, $phone]);
header('Location: index.php');
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Add Student</title>
</head>
<body>
<h1>Add Student</h1>
<form method="POST">
<label>Name:</label><br>
<input type="text" name="name" required><br>
<label>Email:</label><br>
<input type="email" name="email" required><br>
<label>Phone:</label><br>
<input type="text" name="phone" required><br>
<input type="submit" value="Add Student">
</form>
</body>
</html>
```
### Step 6: Edit Student (edit.php)
```php
<?php
include 'config.php';
$id = $_GET['id'];
$stmt = $conn->prepare("SELECT * FROM students WHERE id = ?");
$stmt->execute([$id]);
$student = $stmt->fetch();
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$name = $_POST['name'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$stmt = $conn->prepare("UPDATE students SET name = ?, email = ?, phone = ? WHERE id = ?");
$stmt->execute([$name, $email, $phone, $id]);
header('Location: index.php');
}
?>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Edit Student</title>
</head>
<body>
<h1>Edit Student</h1>
<form method="POST">
<label>Name:</label><br>
<input type="text" name="name" value="<?php echo $student['name']; ?>" required><br>
<label>Email:</label><br>
<input type="email" name="email" value="<?php echo $student['email']; ?>" required><br>
<label>Phone:</label><br>
<input type="text" name="phone" value="<?php echo $student['phone']; ?>" required><br>
<input type="submit" value="Update Student">
</form>
</body>
</html>
```
### Step 7: Delete Student (delete.php)
```php
<?php
include 'config.php';
$id = $_GET['id'];
$stmt = $conn->prepare("DELETE FROM students WHERE id = ?");
$stmt->execute([$id]);
header('Location: index.php');
?>
```
### Final Note
You can run the application by placing the folder in the `htdocs` directory (if using XAMPP) or your web server and navigating to it in your browser. This is a basic implementation of a student management system. For production, consider adding validation, error handling, and security measures such as prepared statements, XSS protection, and CSRF tokens.
