read_exif_data -- Read the EXIF headers from a JPEG
Description
array read_exif_data (string filename)
The read_exif_data() function reads the
EXIF headers from a JPEG image file. It returns an associative
array where the indexes are the Exif header names and the values
are the values associated with those Exif headers. Exif headers
tend to be present in JPEG images generated by digital cameras, but
unfortunately each digital camera maker has a different idea of how
to actually tag their images, so you can't always rely on a specific
Exif header being present.
Example 1. read_exif_data
<?php
$exif = read_exif_data ('p0001807.jpg');
while(list($k,$v)=each($exif)) {
echo "$k: $v<br>\n";
}
?>
