Sample Solution:

PHP Code:

// Define an array of days in a non-leap year
$days = explode(',', '0,31,60,91,121,152,182,213,244,274,305,335');
// Define an array of corresponding day names
$format = explode(',', 'Wednesday,Thursday,Friday,Saturday,Sunday,Monday,Tuesday');

// Continue reading lines from standard input until an empty line is encountered
while (($line = trim(fgets(STDIN))) !== '') {
    // Extract month and day values from the input line
    sscanf($line, '%d %d', $m, $d);

    // Check if the month is 0, which indicates the end of input
    if ($m === 0) {
        break;
    }

    // Calculate the day of the year using the pre-defined array
    $n = $days[$m - 1] + $d;

    // Determine the day of the week using the pre-defined array of day names
    $today = $format[$n % 7];

    // Output the result
    echo "The day is: " . $today, PHP_EOL;
