Third to last verse reads 'Take one down pass it around, 1 bottles of beer on the wall' This is an additional exception that needs to be handled.

<?
/* CONFIG FROM URL STRING, DEFAULT TO 99 BOTTLES OF BEER ON THE WALL*/
if($_REQUEST['bottleNumber']) { $bottleNumber = $_REQUEST['bottleNumber']; } else { $bottleNumber
= 99; }
if($_REQUEST['fluid']) { $fluid = $_REQUEST['fluid']; } else { $fluid = 'beer'; }
if($_REQUEST['location']) { $location = $_REQUEST['location']; } else { $location = 'wall'; }

/* CREATE LYRICS */
for($i = $bottleNumber; $i >= 0; $i--) {

/* SET DEFAULTS */
$bottleCount = $i;
$bottle = 'bottles';
$bottle2 = 'bottles';
$action = 'Take one down and pass it around';
$remainingBottles = $i-1;

/* HANDLE EXCEPTIONS */
if($i == 0)
{
$bottleCount = 'no more';
$action = 'Go to the store and buy some more';
$remainingBottles = $bottleNumber;
}
if($i == 1)
{
$bottle = 'bottle';
$action = 'Take it down and pass it around';
$remainingBottles = 'no more';
}
if($remainingBottles == 1)
{
$bottle2 = 'bottle';
}

/* BUILD LYRICS */
$lyrics .= ucfirst($bottleCount).' '.$bottle.' of '.$fluid.' on the '.$location.',
'.$bottleCount.' '.$bottle.' of '.$fluid.'. '."\n";
$lyrics .= $action.', '.$remainingBottles.' '.$bottle2.' of '.$fluid.' on the '.$location.'.'."\n\n";
}

/* OUTPUT TO PAGE */
echo $lyrics;
?>

Shorter. Faster. Less RAM usage. Oh, and still the same effect...

<?php
if(!$_GET["bottleNumber"]) $_GET["bottleNumber"] = 99;
if(!$_GET["fluid"]) $_GET["fluid"] = "beer"; else $_GET["fluid"] = htmlspecialchars($_GET["fluid"]);
if(!$_GET["location"]) $_GET["location"] = "wall"; else $_GET["location"] = htmlspecialchars($_GET["location"]);

for($i = (int) $_GET["bottleNumber"]; $i > 1; $i--)
echo $i . "bottles of " . $_GET["fluid"] . " on the " . $_GET["location"] . ", " . $i . " bottles of " . $_GET["fluid"] . ".\n" .
"Take one down and pass it around, " . ($i - 1) . " bottles of " . $_GET["fluid"] . " on the " . $_GET["location"] . ".\n\n";

echo "1 bottle of " . $_GET["fluid"] . " on the " . $_GET["location"] . ", 1 bottle of " . $_GET["fluid"] . ".\n" .
"Take one down and pass it around, no more bottles of " . $_GET["fluid"] . " on the " . $_GET["location"] . ".\n\n" .
"No more bottles of " . $_GET["fluid"] . " on the " . $_GET["location"] . ", no more bottles of " . $_GET["fluid"] . ".\n" .
"Go to the store and buy some more, 99 bottles of " . $_GET["fluid"] . " on the " . $_GET["location"];
?>

My opinion is, that the strength of PHP is its ease of use and so this is my version (i know that the purpose of this page/project is to show the features of an programming language, but i think that the feature of PHP actually IS its simplicity):

<?

for ($i=99; $i>=0; $i--)
{
if ($i==0) printf ("No more bottles of beer on the wall, no more bottles of beer. 
Go to the store and buy some more, 99 bottles of beer on the wall. ";
elseif ($i==1) printf ("1 bottle of beer on the wall, 1 bottle of beer. 
Take one down and pass it around, no more bottles of beer on the wall. ";
else printf ($i." bottles of beer on the wall, ".$i." bottles of beer. 
Take one down and pass it around, ".($i-1)." bottles of beer on the wall. ";
}

?>

Thanks to James and Dan for the inspiration. Honestly, I'm sure I can still improve this code. If you have any further suggestions, feel free to email me. Thanks!

<?php

/* 99 bottles of beer by foobarph (http://rllqph.wordpress.com) */
for ($i = 99; $i >= 0; $i--) {

$bottles = $i;
$usedBottles = $i-1;

if ($i == 0) {
$action = "Go to the store and buy some more, ";
$sBottles = "bottle";
$bottles = "no more";
}

if ($i == 1) {
$sBottles = "bottle";
}

if ($i > 1) {
$action = "Take one down and pass it around, ";
$sBottles = "bottles";
}

if ($usedBottles == 0) {
$usedBottles = "no more";
}

if ($usedBottles < 0) {
$usedBottles = "99";
$sBottles = "bottles";
}

echo ucfirst($bottles) . " ". $sBottles ." of beer on the wall, ". $bottles ." ". $sBottles ." of beer. ";
echo $action . $usedBottles ." ". $sBottles ." of beer on the wall. ";
}

?>

I think, this could be written muuuch shorter

5 Lines......

for ($i = 1; $i <= 99; $i++) {
$first = ($i != 99) ? 99 - ($i - 1).' bottles of beer ' : ' 1 bottle of beer ';
$last = ($i == 99) ? ' no more bottles ' : (($i == 98) ? '1 bottle ' : 99 - $i.' bottles ');
echo sprintf('%s on the wall %s Take one down pass it around of %s beer on the wall ', $first, $first, $last);
}

Shortest version possible. Written about 3 years ago.

<?for($i=100;$i--{$a=($i?$i:"no more".$b=" bottl".($i-1?es:e)." of beer";$w=" on the wall";echo ($z++?"$a$w.

":"",ucfirst("$a$w, $a.
",$i?"Take one down and pass it around, ":Go;}echo " to the store and buy some more, 99$b$w.";
