How can SQL queries be optimized in PHP to efficiently sort data based on specific criteria?

To optimize SQL queries in PHP for efficient sorting based on specific criteria, you can use the ORDER BY clause in your SQL query to sort the data directly from the database. Additionally, you can create indexes on the columns you are sorting by to improve query performance. 

// Example SQL query to select data from a table and sort it by a specific column
$sql = "SELECT * FROM table_name ORDER BY column_name ASC";
$result = mysqli_query($connection, $sql);

// Fetch and display the sorted data
while ($row = mysqli_fetch_assoc($result)) {
    echo $row['column_name'] . "<br>";
}
