What potential pitfalls can arise when trying to dynamically generate prepared statements in PHP functions?

One potential pitfall when dynamically generating prepared statements in PHP functions is the risk of SQL injection if input values are not properly sanitized. To mitigate this risk, it is important to use parameterized queries and bind variables securely. Additionally, be cautious when concatenating user input directly into the SQL query as it can lead to vulnerabilities. 

function dynamicPreparedQuery($conn, $tableName, $column, $value) {
    $stmt = $conn->prepare("SELECT * FROM $tableName WHERE $column = ?");
    $stmt->bind_param("s", $value);
    $stmt->execute();
    $result = $stmt->get_result();
    while ($row = $result->fetch_assoc()) {
        // Process the fetched data
    }
    $stmt->close();
}
