How can a PHP developer create a search function for a MySQL database that allows for partial matches?

When creating a search function for a MySQL database that allows for partial matches, PHP developers can use the SQL LIKE operator in their query. This operator allows for wildcard characters, such as '%' for matching any sequence of characters, to be used in the search term. By combining the LIKE operator with PHP variables and concatenation, developers can create a search function that retrieves results with partial matches. 

$searchTerm = $_GET['search']; // Assuming the search term is passed via GET parameter

// Connect to the database
$connection = mysqli_connect('localhost', 'username', 'password', 'database');

// Query to search for partial matches in a specific column
$query = "SELECT * FROM table_name WHERE column_name LIKE '%".$searchTerm."%'";

// Execute the query
$result = mysqli_query($connection, $query);

// Loop through the results
while($row = mysqli_fetch_assoc($result)) {
    // Output the results
    echo $row['column_name'] . "<br>";
}

// Close the connection
mysqli_close($connection);
