This allows the following script:
<?php
// expect $imagefile contains path&filename for an image.
$width = 0;
$height = 0;
$image_type= 0;
$thumbnail = @exif_thumbnail($imagefile, $width, $height, $image_type);
if ($thumbnail===false)
{
// generate and catch or get cached thumbnail
// return cached thumbnail
exit;
}
else
{
// Return content-type of thumbnail
@Header("content-type: ".imagetype2mimetype($image_type));
// and thumbnail itself
echo($thumbnail);
exit;
}
?>
Question:
if i use
$width=$height=$image_type=0;
then all three receive the value of $image_type. Where is the failure?
