How can echoing the generated SQL query in PHP help in debugging issues with database insertion?

When debugging database insertion issues in PHP, echoing the generated SQL query can help identify any errors in the query syntax or data being inserted. By outputting the SQL query before executing it, you can visually inspect the query and ensure that it is correctly formatted and contains the expected data. This can help pinpoint any mistakes or discrepancies that may be causing the insertion to fail. 

// Example code snippet demonstrating how to echo the generated SQL query for debugging database insertion issues

$sql = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";
echo $sql; // Output the SQL query before executing it

// Execute the SQL query
if ($conn->query($sql) === TRUE) {
    echo "Record inserted successfully";
} else {
    echo "Error inserting record: " . $conn->error;
}
