How can the use of SQL commands in PHP help with inserting data into a database table?

Using SQL commands in PHP allows you to interact with a database, including inserting data into a table. By constructing and executing SQL INSERT queries in PHP, you can easily add new records to a database table. This process involves connecting to the database, preparing the SQL query, binding parameters to prevent SQL injection, and executing the query to insert the data. 

<?php
// Establish a connection to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

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

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

// Prepare and execute SQL INSERT query
$stmt = $conn->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");
$stmt->bind_param("ss", $value1, $value2);

// Set values for parameters
$value1 = "value1";
$value2 = "value2";

// Execute the query
$stmt->execute();

// Close the statement and connection
$stmt->close();
$conn->close();
?>
