What potential issue is the user facing with their PHP code when trying to insert data into a MySQL database?

The user may be facing an issue with their PHP code when trying to insert data into a MySQL database due to improper handling of SQL injection vulnerabilities. To solve this issue, the user should use prepared statements with parameterized queries to securely insert data into the database. 

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

// Prepare a SQL statement with placeholders for the data to be inserted
$stmt = $pdo->prepare("INSERT INTO my_table (column1, column2) VALUES (:value1, :value2)");

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

// Set the values to be inserted
$value1 = "value1";
$value2 = "value2";

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