How can PHP developers effectively use fetch_row and fetch_array functions in MySQL queries to improve performance and data retrieval accuracy?

To improve performance and data retrieval accuracy in MySQL queries, PHP developers can use the fetch_row and fetch_array functions to fetch results row by row or as an associative array. This allows for efficient retrieval of data from the database and provides flexibility in how the data is accessed and used in the PHP application. 

// Example of using fetch_row function to fetch results row by row
$query = "SELECT * FROM table_name";
$result = $mysqli->query($query);

while ($row = $result->fetch_row()) {
    // Process each row of data
}

// Example of using fetch_array function to fetch results as an associative array
$query = "SELECT * FROM table_name";
$result = $mysqli->query($query);

while ($row = $result->fetch_array()) {
    // Access data using column names as keys
}
