here's your script,
<?
$mem = "The Childhood
A Man called lallous
The Long kiss good night
Abbey Road
Dark Side Of the Moon
The Final Cut
The Zombie
A Hard Days Night
Kill 'em All
The Wall";
$mem = split("\n", $mem);
$arr1 = array();
for ($i=0;$i<count($mem);$i++)
{
$line = trim($mem[$i]);
$prefix = "";
$affix = $line;
if (preg_match("/^(the |a )(.+)$/i", $line, $matches))
{
$prefix = $matches[1];
$affix = $matches[2];
}
$arr1[$affix] = $prefix;
}
ksort($arr1);
$arr2 = array();
while (list($key, $val) = each($arr1))
{
$arr2[] = "$val$key";
}
var_dump($arr2);
?>
