How can PHP developers avoid SQL syntax errors when dynamically generating query strings with changing column names?

When dynamically generating query strings with changing column names, PHP developers can avoid SQL syntax errors by using prepared statements with placeholders for the column names. This way, the column names are treated as data rather than part of the SQL query, preventing any potential SQL injection attacks and syntax errors. 

// Example code snippet using prepared statements to avoid SQL syntax errors with changing column names

$column_name = 'dynamic_column_name'; // Example of a dynamically changing column name

$stmt = $pdo->prepare("SELECT * FROM table_name WHERE column_name = :value");
$stmt->bindParam(':value', $column_name);
$stmt->execute();

// Loop through the results
while ($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
    // Process the data
}
