What is the potential issue with using the "INSERT INTO" command in PHP to write an array into a database?

Using the "INSERT INTO" command in PHP to write an array into a database can lead to SQL injection vulnerabilities if the array values are not properly sanitized. To solve this issue, you should use prepared statements with parameterized queries to securely insert array values into the database. 

// Assuming $array is the array containing values to be inserted into the database

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

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

// Bind the array values to the placeholders
$stmt->bindParam(':value1', $array['key1']);
$stmt->bindParam(':value2', $array['key2']);

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