How can PHP be used to efficiently search for partial matches in a database column containing author names?

When searching for partial matches in a database column containing author names, you can use the SQL "LIKE" operator along with PHP to efficiently retrieve relevant results. By using a SQL query with a wildcard character (%) in the LIKE clause, you can search for author names that contain a specific substring. In PHP, you can execute this SQL query and fetch the results to display to the user. 

<?php
// Establish a connection to the database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Search term
$searchTerm = "John";

// SQL query to search for partial matches in author names
$sql = "SELECT * FROM authors WHERE author_name LIKE '%" . $searchTerm . "%'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Author: " . $row["author_name"] . "<br>";
    }
} else {
    echo "0 results found for search term: " . $searchTerm;
}

$conn->close();
?>
