PHP Variables and Data Types

What are Variables?

Variables store data—like containers.

$name = "John";
$age = 25;

Common Data Types

String

$name = "Alice";

5. PHP Control Structures

Integer

$age = 30;

Array

$colors = array("Red", "Blue", "Green");

PHP Operators

Operators perform operations.

Arithmetic Operators

$a = 10;
$b = 5;

echo $a + $b; // 15

Comparison Operators

$a == $b
$a != $b

Logical Operators

if ($a > 5 && $b < 10)

Control Statements

If-Else Statement

$age = 18;

if ($age >= 18) {
  echo "Adult";
} else {
  echo "Minor";
}

Switch Statement

$day = "Monday";

switch ($day) {
  case "Monday":
    echo "Start of week";
    break;
}

Loops in PHP

Loops repeat actions.

For Loop

for ($i = 0; $i < 5; $i++) {
  echo $i;
}

While Loop

$i = 0;
while ($i < 5) {
  echo $i;
  $i++;
}

Foreach Loop

$colors = ["Red", "Blue"];

foreach ($colors as $color) {
  echo $color;
}

Functions in PHP

function greet($name) {
  echo "Hello " . $name;
}

greet("John");

Working with Forms

GET vs POST

Method	Description
GET	Data sent via URL
POST	Data sent securely

<form method="post">
  <input type="text" name="username">
  <input type="submit">
</form>

echo $_POST['username'];

PHP and MySQL Tutorial

Database Connection

$conn = mysqli_connect("localhost", "root", "", "test");

Simple Query

$result = mysqli_query($conn, "SELECT * FROM users");

Real-World Project: Login System

Step-by-Step

Step 1: Create Database

CREATE TABLE users (
  id INT AUTO_INCREMENT PRIMARY KEY,
  username VARCHAR(50),
  password VARCHAR(50)
);

Step 2: HTML Form

<form method="post">
  <input name="username">
  <input name="password">
  <button>Login</button>
</form>

Step 3: PHP Logic

$username = $_POST['username'];
$password = $_POST['password'];

$query = "SELECT * FROM users WHERE username='$username' AND password='$password'";
