How can SQL injection vulnerabilities be mitigated when inserting data from an external file into a database using PHP?

SQL injection vulnerabilities can be mitigated by using prepared statements with parameterized queries when inserting data from an external file into a database using PHP. This approach ensures that user input is treated as data rather than executable SQL code, preventing malicious SQL injection attacks. 

// Assuming $conn is the database connection object and $data is the data from the external file

$stmt = $conn->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");
$stmt->bind_param("ss", $data['value1'], $data['value2']);
$stmt->execute();
$stmt->close();
