PHP Documentation Group 												IMAGE_TYPE_TO_MIME_TYPE(3)

EXIF_IMAGETYPE(3)							 1							 EXIF_IMAGETYPE(3)

exif_imagetype - Determine the type of an image

SYNOPSIS

       int exif_imagetype (string  $filename)

DESCRIPTION

       exif_imagetype(3) reads the first bytes of an image and checks its signature.

       exif_imagetype(3)   can	 be  used  to  avoid  calls  to  other	exif  functions  with  unsupported  file  types  or  in  conjunction  with
       $_SERVER['HTTP_ACCEPT'] to check whether or not the viewer is able to see a specific image in the browser.

PARAMETERS

	      o $filename
		- The image being checked.

RETURN VALUES

	When a correct signature is found, the appropriate constant value will be returned otherwise the return value is FALSE. The  return  value
       is the same value that getimagesize(3) returns in index 2 but exif_imagetype(3) is much faster.

       Note

	      exif_imagetype(3)  will  emit an E_NOTICE and return FALSE if it is unable to read enough bytes from the file to determine the image
	      type.
