What alternative approach can be used to create a timer in PHP without running into the maximum execution time limit issue?

When creating a timer in PHP, the maximum execution time limit can be an issue if the timer runs for a long duration. To avoid hitting this limit, one alternative approach is to use PHP's `set_time_limit()` function to increase the maximum execution time for the script. By periodically resetting the timer using this function, the script can continue running without being terminated due to reaching the maximum execution time limit. 

// Set the maximum execution time limit to 0 (unlimited)
set_time_limit(0);

// Start time
$start_time = time();

// Set the duration for the timer (in seconds)
$duration = 60;

// Loop until the timer duration is reached
while((time() - $start_time) < $duration) {
    // Perform timer-related tasks here
    // For example, display the remaining time
    echo "Time remaining: " . ($duration - (time() - $start_time)) . " seconds\n";

    // Reset the time limit to prevent hitting the maximum execution time
    set_time_limit(30); // Reset time limit every 30 seconds
}
