How can one ensure data integrity when working with Oracle DB in PHP?

To ensure data integrity when working with Oracle DB in PHP, one can use prepared statements to prevent SQL injection attacks and validate input data before inserting or updating records in the database. 

// Establish a connection to the Oracle database
$conn = oci_connect('username', 'password', 'localhost/XE');

// Prepare a SQL statement with placeholders
$sql = 'INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)';
$stmt = oci_parse($conn, $sql);

// Bind input parameters to the placeholders
oci_bind_by_name($stmt, ':value1', $value1);
oci_bind_by_name($stmt, ':value2', $value2);

// Validate input data before executing the statement
if (!empty($value1) && !empty($value2)) {
    // Execute the prepared statement
    oci_execute($stmt);
} else {
    echo 'Input data is invalid';
}

// Close the connection to the Oracle database
oci_close($conn);
