How can PHP be used to create a detailed search feature using MySQL database variables?

To create a detailed search feature using MySQL database variables in PHP, you can use a form to collect search criteria from users and then construct a SQL query based on the input. The SQL query can include various conditions using database variables to filter the results based on the user's search parameters. 

<?php
// Connect to 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);
}

// Get search criteria from form
$search_term = $_POST['search_term'];

// Construct SQL query with database variables
$sql = "SELECT * FROM table_name WHERE column_name LIKE '%$search_term%'";

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

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

// Close database connection
$conn->close();
?>
