إنشاء الجداول وملؤها

ما الجداول في قاعدة البيانات؟

| ID | Name     | Email           |
|----|----------|-----------------|
| 1  | Alice    | alice@mail.com  |
| 2  | Bob      | bob@mail.com    |

إنشاء جدول باستخدام SQL

CREATE TABLE users (
  id INT AUTO_INCREMENT PRIMARY KEY,
  name VARCHAR(50) NOT NULL,
  email VARCHAR(50) NOT NULL,
  created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

إنشاء جداول باستخدام PHP

<?php
  $sql = "CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(50) NOT NULL,
    email VARCHAR(50) NOT NULL,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
  )";

  try {
    $pdo->exec($sql);
    echo "Table created successfully!";
  } catch (PDOException $e) {
    echo "Error creating table: " . $e->getMessage();
  }
?>

إدراج البيانات في جدول

<?php
  $sql = "INSERT INTO users (name, email) VALUES (:name, :email)";
  $stmt = $pdo->prepare($sql);
  $stmt->execute(["name" => "Alice", "email" => "alice@mail.com"]);

  echo "Data inserted successfully!";
?>

إدراج سجلات متعددة

<?php
  $users = [
    ["name" => "Bob", "email" => "bob@mail.com"],
    ["name" => "Charlie", "email" => "charlie@mail.com"]
  ];

  $sql = "INSERT INTO users (name, email) VALUES (:name, :email)";
  $stmt = $pdo->prepare($sql);

  foreach ($users as $user) {
    $stmt->execute($user);
  }

  echo "Multiple records inserted successfully!";
?>

عرض البيانات في جدول

<?php
  $sql = "SELECT * FROM users";
  $stmt = $pdo->query($sql);

  while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
    echo "ID: " . $row["id"] . ", Name: " . $row["name"] . ", Email: " . $row["email"] . "<br>";
  }
?>

التعامل مع الأخطاء

<?php
  try {
    $stmt = $pdo->prepare($sql);
    $stmt->execute(["name" => "Dave", "email" => "dave@mail.com"]);
    echo "Data inserted successfully!";
  } catch (PDOException $e) {
    echo "Error: " . $e->getMessage();
  }
?>
