How can you optimize a PHP SELECT query to efficiently search for data based on partial matches in a cell?

When searching for data based on partial matches in a cell, you can optimize a PHP SELECT query by using the LIKE operator in your SQL query. This operator allows you to search for patterns within a column's value. To efficiently search for partial matches, you can use the % wildcard character before and/or after the search term to match any sequence of characters. 

<?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
$search_term = "partial";

// SQL query to select data based on partial matches
$sql = "SELECT * FROM table_name WHERE column_name LIKE '%$search_term%'";

$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Column Value: " . $row["column_name"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
?>
