What are the considerations when balancing the visual presentation and functionality of a search feature in PHP when using text files?

When balancing the visual presentation and functionality of a search feature in PHP using text files, it's important to consider the user interface design to make the search feature intuitive and easy to use, while also ensuring that the search functionality is efficient and accurate. This can be achieved by designing a clean and user-friendly search form and result display, while also optimizing the search algorithm to efficiently scan through the text files. 

<?php
// Example PHP code for implementing a search feature using text files

// Function to search for a keyword in a text file
function searchInTextFile($keyword, $filename) {
    $results = array();
    $lines = file($filename);
    
    foreach($lines as $line) {
        if(strpos($line, $keyword) !== false) {
            $results[] = $line;
        }
    }
    
    return $results;
}

// Example usage
$keyword = "example";
$filename = "data.txt";
$results = searchInTextFile($keyword, $filename);

// Display search results
if(!empty($results)) {
    foreach($results as $result) {
        echo $result . "<br>";
    }
} else {
    echo "No results found.";
}
?>
