What are some best practices for implementing a search function in PHP using PHP Magic Plus?

Implementing a search function in PHP using PHP Magic Plus involves creating a form where users can input search terms, processing the input in PHP to query a database or search through data, and displaying the results to the user.

<?php
// Check if form is submitted
if(isset($_POST['search'])) {
    $searchTerm = $_POST['searchTerm'];
    
    // Perform search query
    // Replace this with your own search logic
    $results = searchFunction($searchTerm);
    
    // Display search results
    foreach($results as $result) {
        echo $result . "<br>";
    }
}

// HTML form for search input
?>
<form method="post" action="">
    <input type="text" name="searchTerm">
    <input type="submit" name="search" value="Search">
</form>
