How can SQL syntax errors be avoided when inserting data into a database using PHP?

SQL syntax errors can be avoided when inserting data into a database using PHP by using prepared statements. Prepared statements separate the SQL query from the data being inserted, preventing SQL injection attacks and ensuring proper syntax. This can be achieved by using PDO (PHP Data Objects) or MySQLi extension in PHP. 

// Using PDO to insert data into a database with prepared statements
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

$stmt = $pdo->prepare("INSERT INTO mytable (column1, column2) VALUES (:value1, :value2)");
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);

$value1 = "data1";
$value2 = "data2";

$stmt->execute();
