How Can I Efficiently Loop Through MySQL Result Sets in PHP?

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.
