What are the best practices for efficiently searching through a MySQL database using PHP?

When searching through a MySQL database using PHP, it is important to use SQL queries efficiently to retrieve the desired data. One way to optimize the search process is to use prepared statements to prevent SQL injection attacks and improve performance. Additionally, using indexes on columns that are frequently searched can help speed up the search process. 

// Establish a connection to the MySQL 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);
}

// Prepare a SQL statement with a placeholder for the search term
$stmt = $conn->prepare("SELECT * FROM table_name WHERE column_name = ?");
$search_term = "search_query";
$stmt->bind_param("s", $search_term);

// Execute the prepared statement
$stmt->execute();

// Bind the results to variables
$stmt->bind_result($result1, $result2);

// Fetch and display the results
while ($stmt->fetch()) {
    echo $result1 . " - " . $result2 . "<br>";
}

// Close the statement and connection
$stmt->close();
$conn->close();
