How can the max() and array_search() functions be used in PHP to find the highest similarity percentage and corresponding filename in an array?

To find the highest similarity percentage and corresponding filename in an array, you can use the max() function to find the highest similarity percentage and then use the array_search() function to find the corresponding filename based on that percentage. First, calculate the similarity percentages and store them in an array with filenames as keys. Then, use max() to find the highest percentage and array_search() to retrieve the corresponding filename. 

// Calculate similarity percentages and store them in an array with filenames as keys
$similarityPercentages = [
    'file1.txt' => 90,
    'file2.txt' => 85,
    'file3.txt' => 95,
];

// Find the highest similarity percentage
$highestPercentage = max($similarityPercentages);

// Find the corresponding filename
$highestFilename = array_search($highestPercentage, $similarityPercentages);

echo "The highest similarity percentage is " . $highestPercentage . "% for file: " . $highestFilename;
