Just to add to the above response, he missed a couple of IPTC tags:
Keywords:
$iptc["2#025"][n];  (there is a list of keywords)
Caption Writer:
$iptc["2#122"][0];
Just figured I'd note it, as the keywords can be quite important for database applications. I got these by extracting IPTC tags from a Photoshop 6.0 file, so hopefully they are standardized ;)

To import IPTC keywords (which are stored in an array) into a scalar, try this sort of approach:
$keywordcount = count($iptc["2#025"]);
for ($i=0; $i
Of course, this will only preserve ISO-8859-1 characters.
For proper Unicode support, you should convert UTF-8 byte sequences into HTML character entities, or encode the whole web page in UTF-8.

I've managed to update "pkrohn at daemonize dot com" array, after 12 years since initial publication.
If you want to change some of IPCT header-strings into something more human-readable, try to use array similar to this:
$iptcHeaderArray = array
(
  '2#005'=>'DocumentTitle',
  '2#010'=>'Urgency',
  '2#015'=>'Category',
  '2#020'=>'Subcategories',
  '2#040'=>'SpecialInstructions',
  '2#055'=>'CreationDate',
  '2#080'=>'AuthorByline',
  '2#085'=>'AuthorTitle',
  '2#090'=>'City',
  '2#095'=>'State',
  '2#101'=>'Country',
  '2#103'=>'OTR',
  '2#105'=>'Headline',
  '2#110'=>'Source',
  '2#115'=>'PhotoSource',
  '2#116'=>'Copyright',
  '2#120'=>'Caption',
  '2#122'=>'CaptionWriter'
);

View all availiable IPCT Data
function output_iptc_data( $image_path ) {  
  $size = getimagesize ( $image_path, $info);    
   if(is_array($info)) {  
    $iptc = iptcparse($info["APP13"]);
    foreach (array_keys($iptc) as $s) {       
      $c = count ($iptc[$s]);
      for ($i=0; $i
