php saemysql

PHP is a popular programming language used for web development. It can be used to connect and interact with MySQL databases.

To connect to a MySQL database in PHP, you can use the mysqli or PDO extensions. Here's an example of connecting to a MySQL database using mysqli:

<?php
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

echo "Connected successfully";
?>

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

Once connected, you can perform various database operations using PHP, such as querying data, inserting records, updating records, and deleting records. Here's an example of querying data from a table:

$sql = "SELECT * FROM your_table";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "ID: " . $row["id"]. " - Name: " . $row["name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();

Replace "your_table" with the actual table name from your database.

Remember to handle errors and sanitize user input to prevent SQL injection attacks.
