Warning: exif_read_data(indirajoshi_001.jpg) [function.exif-read-data]: Incorrect APP1 Exif Identifier Code in c:documents and settingsUSERmy documentsniceheader.php on line 36

Perhaps the script below could help, it shows how to extract single items.

$file = "test.jpg"; // Change this to your own image file path

$exif = exif_read_data($file, 0, true);

/*
So far i noticed, there are 7 entities:
(FILE - COMPUTED - IFD0 - THUMBNAIL - COMMENT - EXIF - WINXP)
Each entity containing there own attributes
Below some sample code of how to extract a single entity and attribute.
*/

print "

All Entities and Attributes (avaiable for specified document)

";

foreach($exif as $key => $val)
{
print "

".$key."

";
foreach($val as $singleAttribute => $val2)
{
print "".$singleAttribute.": ".$val2."
";
}
print "

";
}

print "

Read Specified Attributes

";

// WINXP entity attributes can be edited by clicking on your file:
// Right Mouse Button > Properties > Summary
// Below you see how to extract single attributes

// In the first bracket you put the entity name
// The second bracket the attribute name
print "Model: ".$exif["IFD0"]["Model"]."
";
print "Flash: ".$exif["EXIF"]["Flash"]."
";
print "Compression: ".$exif["THUMBNAIL"]["Compression"]."
";
print "Title: ".$exif["WINXP"]["Title"]."
";
print "Html: ".$exif["COMPUTED"]["html"]."
";
print "Mime-Type: ".$exif["FILE"]["MimeType"]."
";
?>

This was really informative, but doesn't tell us how we can edit the output in a way that we can manually control. For example if I didn't want to show all of the EXIF variables, only a select few.

Any information on how I can re-style that mess would be so appreciated!
