What are the potential performance implications of using PHP to search through a MySQL table versus using a SQL statement for the search?

When using PHP to search through a MySQL table, there can be potential performance implications due to the need to transfer large amounts of data between the database and the PHP script. This can lead to increased memory usage and slower processing times compared to executing a SQL statement directly in the database. To improve performance, it is recommended to use SQL queries for searching through MySQL tables instead of relying on PHP to handle the search logic. 

// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Define search query
$search_term = "example";
$sql = "SELECT * FROM table_name WHERE column_name LIKE '%$search_term%'";

// Execute query
$result = $mysqli->query($sql);

// Process search results
if ($result->num_rows > 0) {
    while($row = $result->fetch_assoc()) {
        // Output search results
        echo "ID: " . $row["id"] . " - Name: " . $row["name"] . "<br>";
    }
} else {
    echo "No results found.";
}

// Close database connection
$mysqli->close();
