How can PHP be used to compare data from two text files?

To compare data from two text files using PHP, you can read the contents of each file into separate variables and then use a comparison operator (such as == or ===) to check if the data is the same or different. You can also use functions like file_get_contents() to read the files and then compare the data using PHP's built-in string comparison functions. 

$file1 = file_get_contents('file1.txt');
$file2 = file_get_contents('file2.txt');

if ($file1 === $file2) {
    echo "The contents of file1.txt and file2.txt are the same.";
} else {
    echo "The contents of file1.txt and file2.txt are different.";
}
