What are the advantages of using SQL directly for filtering data in PHP applications?

When filtering data in PHP applications, using SQL directly can offer several advantages such as improved performance, easier implementation of complex filtering logic, and better integration with the database system. By leveraging SQL's powerful querying capabilities, developers can efficiently retrieve only the data that meets specific criteria without having to manipulate large datasets in PHP code. 

<?php
// Establish a connection to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

// Define the SQL query with filtering criteria
$sql = "SELECT * FROM table_name WHERE column_name = 'filter_value'";

// Execute the query and fetch the results
$result = $conn->query($sql);
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        // Process the filtered data as needed
    }
} else {
    echo "No results found";
}

// Close the database connection
$conn->close();
?>
