How does optimizing SQL queries in PHP contribute to performance improvements in database operations?

Optimizing SQL queries in PHP can contribute to performance improvements in database operations by reducing the amount of data that needs to be processed, minimizing the number of database calls, and improving the overall efficiency of the query execution. This can result in faster response times and reduced server load, ultimately leading to a better user experience. 

// Example of optimizing SQL query in PHP
$sql = "SELECT column1, column2 FROM table WHERE condition = 'value'";
$result = mysqli_query($connection, $sql);

// Process the result set
while ($row = mysqli_fetch_assoc($result)) {
    // Do something with the data
}

mysqli_free_result($result);
mysqli_close($connection);
