Present a program which emits the lyrics to the song I Knew an Old Lady Who Swallowed a Fly, taking advantage of the repetitive structure of the song's lyrics.

Old lady swallowed a fly is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

PHP

<lang php><?php

$swallowed = array( 

 array('swallowed' => 'fly.',
       'reason' => "I don't know why she swallowed the fly."),
 array('swallowed' => 'spider,',
       'aside' => "which wiggled and jiggled and tickled inside her.",
       'reason' => "She swallowed the spider to catch the fly"),
 array('swallowed' => 'bird.',
       'aside' => "How absurd! To swallow a bird!",
       'reason' => "She swallowed the bird to catch the spider,"),
 array('swallowed' => 'cat.',
       'aside' => "Imagine that! To swallow a cat!",
       'reason' => "She swallowed the cat to catch the bird."),
 array('swallowed' => 'dog.',
       'aside' => "What a hog! To swallow a dog!",
       'reason' => "She swallowed the dog to catch the cat."),
 array('swallowed' => 'horse',
       'aside' => "She's dead, of course. She swallowed a horse!",
       'reason' => "She swallowed the horse to catch the dog."));

foreach($swallowed as $creature) { 

 print "I knew an old lady who swallowed a " . $creature['swallowed'] . "\n";
 if(array_key_exists('aside', $creature))
   print $creature['aside'] . "\n";

 $reversed = array_reverse($swallowed);
 $history = array_slice($reversed, array_search($creature, $reversed));

 foreach($history as $note)
 {
   print $note['reason'] . "\n";
 }

 if($swallowed[count($swallowed) - 1] == $creature)
   print "But she sure died!\n";
 else
   print "Perhaps she'll die." . "\n\n";
