How can PHP be used to read a text file line by line and separate day and month values for date comparison?

To read a text file line by line and separate day and month values for date comparison in PHP, you can use the `fgets()` function to read each line of the file and then use `explode()` to separate the day and month values from the date string. You can then compare these values as needed for date comparison.

$file = fopen("dates.txt", "r");

while(!feof($file)) {
    $line = fgets($file);
    $date_parts = explode("/", $line); // Assuming date format is day/month/year

    $day = $date_parts[0];
    $month = $date_parts[1];

    // Perform date comparison logic here

}

fclose($file);
