What potential issues can arise when using PHP to insert data into a database?

One potential issue when using PHP to insert data into a database is SQL injection attacks, where malicious code is inserted into input fields to manipulate the database. To prevent this, you should use prepared statements with parameterized queries to sanitize user input. 

// Using prepared statements to insert data into a database
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);

// Set parameter values
$value1 = $_POST['input1'];
$value2 = $_POST['input2'];

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