What are the drawbacks of using multiple mysql_result calls in PHP to retrieve data from a MySQL query result?

Using multiple mysql_result calls in PHP to retrieve data from a MySQL query result can be inefficient and error-prone. Each mysql_result call requires additional processing and communication with the database server, which can slow down the script execution. It is recommended to fetch all the data from the query result at once and then access the individual rows and columns as needed.

// Fetch all data from the query result
$result = mysql_query($query);

// Check if the query was successful
if ($result) {
    // Fetch all rows into an array
    $data = array();
    while ($row = mysql_fetch_assoc($result)) {
        $data[] = $row;
    }

    // Access individual rows and columns as needed
    foreach ($data as $row) {
        echo $row['column_name'];
    }
} else {
    echo "Error executing query: " . mysql_error();
}
