How can developers avoid SQL injection vulnerabilities when using ADODB?

Developers can avoid SQL injection vulnerabilities when using ADODB by using parameterized queries instead of concatenating user input directly into SQL queries. This helps to prevent malicious user input from being interpreted as part of the SQL query and potentially causing harm. 

// Connect to the database
$conn = ADONewConnection('mysql');
$conn->Connect('localhost', 'username', 'password', 'database');

// Prepare a parameterized query
$sql = "SELECT * FROM users WHERE username = ?";
$stmt = $conn->Prepare($sql);

// Bind user input to the query parameters
$username = $_POST['username'];
$conn->Execute($stmt, array($username));

// Fetch the results
$results = $conn->GetArray($stmt);

// Use the results as needed
foreach ($results as $row) {
    echo $row['username'] . '<br>';
}

// Close the connection
$conn->Close();
