Rather than looping through an array with 26 values, or worse yet, typing out 26 lines of code, just loop through the display code 26 times.

<?php
for ($i=65; $i<=90; $i++) {
 echo chr($i);
}
?>

For those not familiar with ASCII mappings, values 65-90 represent the uppercase letters A-Z. Alternately, you could use the values 97-122 for lowercase a-z.  If you wanted to mix the two (say to display uppercase, but use lowercase in the link) just use the strtoupper() or strtolower() functions inside the loop.  Here’s a more applicable sample:

<?php
for ($i=97; $i<=122; $i++) {
 $x = chr($i);
 echo '<a href="memberlist.php?alpha=' . $x . '>' . strtoupper($x) . '</a>';
}
?>

You can see an example of both applied here.

                          

Trance:

Eric Jordan

By far, I spend the most time listening to Eric Jordan.  His trance mixes are stunning.  They are always creative, drawing from his vast knowlege of obscure, but impressive tracks.  He is a master at creating a mood, evoking emotion, and pulling the listener in.  Every month he posts a new mix on his website: neverrain.com, available for free to download.  His mixes tend to have more subtle melodies, and less vocals, so I find them extra conducive to zoning out and programming complex algorithms.

Vocal Trance:

DJ GT

DJ GT takes a similar approach, creating hour long mixes and posting them for free on his website, generationtrance.com. He is equally talented, although his track lists tend to be slightly more mainstream.  All of the songs he uses contain lyrics, which makes the mixes a little more structured and digestable for those not as used to electronic music.  I’ll throw one of his many tracks in the queue when I want something more upbeat to tap my feet to.

Psycadelic Trance:

Shpongle

Shpongle is group out of the UK that defies description.  Generally, I’d label it Psy Trance, but you’ll find heavy influences of world beat, classical, opera, jazz, ska, punk, dub, and half a dozen other genres.  It all adds up to 100% awesome.  Lyrics in their music are not arranged into verses to tell a story, but rather sampled to become part of the ambience and reinforce the mood.  My only wish is that they had more than three albums.

Dub:

OTT

If I had to describe Dub to someone who hadn’t heard it, I’d label it the offspring of Reggae and Trance.  It’s characterized by a slower tempo than most electronica, with a heavier bassline and more emphasis on the ambience of the music.  Ott’s first album Blumenkraft stands out as my favorite mix of any artist mentioned here.  It’s simply the most powerful weapon against the drone of office background noise I’ve found.  I save it for when I need to write that recursive function I’ve been putting off all week.

Industrial:

Front Line Assembly

Two of my favorite artists are Bill Leeb and Rhys Fulber.  They’ve been making electronic music for two decades, and they’ve made some of the best.  They’ve gone under several different names, the most popular being Delerium and Front Line Assembly.  Delerium, like Shpongle, defies description and has gone through several distinct transitions through the years.  I own and love the entire collection, but the music I find best to program to however, are their oldest albums, found here and here.  Each of those are a two CD set that compiles all the their earliest releases which are (sadly) no longer available.  The music is very experimental, and it laid the groundwork for the industrial genre.

                          

• You can’t start it on the first of the month – The first will likely fall mid-week
• To find the acutual first day of the week, you need to know how many days are in the previous month and count backwards
• You cannot assume 4 weeks per month -most have 5 or 6
• you will need to use the correct number of days in the month, and then add on the correct number of days of the next month to finish the week

After playing with a few algorithms, I decided to represent the month with a 2-dimensional array, one index for each week, and another for each day.  Then, you can put the actual string date in each value, or perhaps an array with that day’s events.  Without further ado:

<?php
//CreateMonthView -
//Takes one parameter: a unix timestamp anywhere in the month
function CreateMonthView( $now ) {

    //get numberic day of month (01-31)
    $dayOfMonth = strftime('%d', $now);
    //subtract as approptriate to get to start of month
    $monthStart = $now - (86400 * ($dayOfMonth -1));

    //get numeric day of week (0-6)
    $dayOfWeek = strftime('%w', $monthStart);

    //subtract appropriate number of days to get to the start of the week
    //this will usually be the last part of the previous month
    $calMonthStart = $monthStart - (86400 * $dayOfWeek );

    //initialize variables for while loop
    $thisWeekStart = $calMonthStart;
    $week = 1;
    $monthArray = array();

    //last day of month - text condition for while loop
    $lastDayOfMonth = mktime(23, 59, 59,
                             date("m", $now),
                             date("t", $now),
                             date("Y", $now));

    //foreach week, create a new array to hold the days
    while( $thisWeekStart <= $lastDayOfMonth ) {
        $monthArray[$week] = array();

        //iterate through week - adding each day as a value
        for( $i=0; $i<7; $i++) {
            //get timestamp for each day
            $dayOfWeek = $thisWeekStart + 86400 * $i;
            //convert to a and ISO date - seconds are too precise
            $date = date('Y-m-d',$dayOfWeek);

            //each day will be the value in the array
            $monthArray[$week][] = $date;
        }

        //increment sentinal variable and week counter
        $thisWeekStart = $dayOfWeek + 86400;
        $week++;
    }

    return $monthArray;
}
?>

Now you may be saying to yourself “okay, that’s all fine and good, but it doesn’t do anything on it’s own”, and you’d be right, it’s just a function.  To make something happen, you simply need to call it, and display the result.  Here is another snippet that does just that:

<?php
$month = CreateMonthView( mktime() ); //create the current month

echo '<table>';
foreach( $month as $week ) {
    echo '<tr>';

    foreach ($week as $day ) {
        if( $day == date('Y-m-d') ){
            //apply selector to distinguish today's date
            echo '<td class="today">';
        } else {
            echo '<td>';
        }
        //reduce the complete ISO date down to the day and display it
        echo substr($day, 8, 2);
        echo '</td>';
    }
    echo "</tr>\n";
}
echo '</table>';
?>

Viola! You can certainly copy and paste this code as is, but it’s not very visually exciting. Here’s an example. It could definitely use some styling – but I’ll leave that up to you.

                          

//Get the total number of rows from the MySQL database
$query = "SELECT COUNT(*) as total FROM table";
$result = mysql_query( $query);
$rows = mysql_fetch_assoc( $result );

//Let PHP choose a random row
//pick a number between 1 & the total
$row = rand(1, $rows['total'])

//Now get that row
$query = "SELECT * FROM table LIMIT($row, 1)";
$result = mysql_query( $query);

After typing that out, I realized that I had take the long way round the problem. Very similar to taking the Misty Mountain Path rather than the Mines of Moria. Here’s a better way:

//Get a random row from the database
$query = "SELECT * FROM table ORDER BY RAND() LIMIT 1";
$result = mysql_query( $query );

Much better. Gimley the dwarf would be proud
