What are the best practices for handling errors or displaying messages when a specific search term is not found in the file content in PHP?

When a specific search term is not found in the file content in PHP, it is important to handle this error gracefully by displaying a user-friendly message to the user. One way to do this is by checking if the search term exists in the file content before attempting to process it further. If the search term is not found, display a message informing the user that the term was not found. 

<?php
// Read the file content
$file_content = file_get_contents('example.txt');

// Search term
$search_term = 'example';

// Check if the search term exists in the file content
if (strpos($file_content, $search_term) !== false) {
    // Process the search results
    // Display search results to the user
    echo "Search results for '{$search_term}': ...";
} else {
    // Display a message if search term is not found
    echo "The search term '{$search_term}' was not found.";
}
?>
