What are the advantages and disadvantages of using a text file, MySQL, or Excel for storing data in PHP?

When deciding on which method to use for storing data in PHP, it is important to consider the advantages and disadvantages of text files, MySQL, and Excel. Text files are simple and easy to work with, but they are not suitable for storing large amounts of data or complex data structures. MySQL is a powerful relational database management system that allows for efficient querying and data manipulation, but it requires a server setup and can be more complex to work with. Excel files are user-friendly and widely used, but they are not designed for large-scale data storage and can be cumbersome to work with programmatically. 

// Example PHP code snippet for storing data in a MySQL database

// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

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

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

// Insert data into MySQL table
$sql = "INSERT INTO data_table (column1, column2, column3) VALUES ('value1', 'value2', 'value3')";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

// Close connection
$conn->close();
