# Depending on your clientside javascript, you need to pass the file name to the the method
# It might be passed through the query string. eg $_GET['filename']

# This allows you to upload files to different directories on the fly
# .zip is appended to the filename
# The third parameter determines if the original file should be kept as well or removed
# It returns an array of the filename(zipped), filepath(zipped) and if 3rd param is true, original_filename and original filepath on success
# and false on failure
# This requires you to have PclZip in the same directory

# Third param if set to true, will remove exif data using GD functions if file is an image. Certain images maybe renamed with a .jpg extension
# Fourth param will upload the file image resized if it is an image. Script will determine correct ratio and upload file as such.
# Notice that strict mode is set to false. If thumbnail mode and strict are set to true, thumbnail mode takes precedence.
# Only files marked as image in the file_mime array are affected by image checks and functions since these are the commonly supported files
# on GD
# The method returns an array of filename and filepath on success and false on failure
