Exploring Techniques to Loop Through MySQL Result Sets
In the realm of PHP and MySQL, traversing the results of your database queries is a crucial task. If you're a budding PHP developer, understanding the methods to efficiently iterate through result sets is essential.
One common approach is the mysql_fetch_array() method. This method returns an associative array representing each row of the result set. Let's explore how it works:
<?php // Connect to the database $link = mysql_connect(/*arguments here*/); // Define the query $query = sprintf("select * from table"); // Execute the query and store the result $result = mysql_query($query, $link); // Check if the query was successful if ($result) { // Loop through the rows while($row = mysql_fetch_array($result)) { // Manipulate the row data } } else { // Handle query errors echo mysql_error(); } ?>
Within the while loop, the $row variable is assigned a new associative array for each iteration, providing access to the columns through array keys. This approach allows you to easily work with and analyze your query results.
