How can PHP be used to open and read the contents of a file?

To open and read the contents of a file using PHP, you can use the `fopen()` function to open the file, `fread()` function to read the contents, and `fclose()` function to close the file handle once you are done. Make sure to handle any errors that may occur during the process. 

$filename = 'example.txt';
$handle = fopen($filename, 'r');

if ($handle) {
    $contents = fread($handle, filesize($filename));
    fclose($handle);
    
    echo $contents;
} else {
    echo "Unable to open file.";
}
