So you want to be able to see what day it is and then fill an array to display something later on. This is how I did it. I am using this to track events happening within the following week. It could be used for a calendar system and so on.

coming_soon.php

<?php

    # Define the days of the week
    $days = array(
        'Friday',
        'Saturday',
        'Sunday',
        'Monday',
        'Tuesday',
        'Wednesday',
        'Thursday'
    );

    # Shift the days until it matches today :-D
    while(current($days) !== date('l', time()))
    {
        $days[] = array_shift($days);
    }

    # You can then do anything which you fill the array up with and loop through it thereafter.
    # A good example is for a meeting system, or a calender system.
    # So if today was Tuesday I could add meetings for today and thursday

    # Let's say we have a meetings array
    $meetings = array( "week" => array() );

    # Let's loop though our days array and create the weeks calender per day
    foreach($days as $day)
    {
        $meetings["week"][$day] = array();
    }

    # using a small sample set, let's add data to the array to iterate through later on.
    $meetings["week"]['Monday'][] = "Get a job";
    $meetings["week"]['Friday'][] = "TGIF";
    $meetings["week"]['Tuesday'][] = "Take a run";

    # Now even though the order we inserted the up and coming events, we can cycle through the
    # days array and the events will be in order of first possible occurrence.
    echo "<h3>Coming in the next week:</h3>";

    # Loop through the days
    foreach($meetings["week"] as $dayOfWeek=>$dayEvents)
    {
        # Now I just want to make sure the day has an event
        if (!empty($dayEvents))
        {
            echo "<p>";
            echo "<b>" . $dayOfWeek . "</b><br />";
            echo "<ul>";

            # We can now cycle through the events of the day and group it for the day
            foreach($dayEvents as $event)
            {
                echo "<li>" . $event . "</li>";
            }

            echo "</ul>";
            echo "</p>";
        }
    }
