Are there any common mistakes to avoid when inserting data into a MySQL table using PHP?

One common mistake to avoid when inserting data into a MySQL table using PHP is failing to properly sanitize user input, which can leave your application vulnerable to SQL injection attacks. To prevent this, always use prepared statements with parameterized queries to safely insert data into your database.

// Establish a database connection
$pdo = new PDO("mysql:host=localhost;dbname=database_name", "username", "password");

// Prepare a SQL query with placeholders
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");

// Bind the parameters with values
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);

// Set the values of the parameters
$value1 = "some_value";
$value2 = "some_other_value";

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