How can the similar_text() function be utilized to compare user input with filenames for similarity in PHP?

To compare user input with filenames for similarity in PHP, you can use the similar_text() function to calculate the similarity percentage between the user input and each filename. You can then set a threshold percentage to determine if the user input is similar enough to a filename. This can help in suggesting possible matches or auto-correcting user input. 

$userInput = "file1.txt";
$filenames = ["file1.txt", "file2.txt", "file3.txt"];

foreach ($filenames as $filename) {
    similar_text($userInput, $filename, $similarityPercentage);
    
    if ($similarityPercentage >= 80) {
        echo "Possible match found: " . $filename . "\n";
    }
}
