PHP：exif_imagetype（）函数如何接受JPG文件（而不是JPEG文件）？

Question

I'm using the PHP exif_imagetype() function, and trying to accept these types of images:

IMAGETYPE_PNG

IMAGETYPE_JPEG

IMAGETYPE_GIF

But there's no IMAGETYPE_JPG imagetype constant, so all .jpg files are not accepted. Is there any solution to this?

Answer 1

IMAGETYPE_JPEG works for files with extensions jpg and jpeg :

var_dump(exif_imagetype ( "abc.jpg" ) == IMAGETYPE_JPEG);
var_dump(exif_imagetype ( "abc.jpeg" ) == IMAGETYPE_JPEG);

outputs

bool(true)
bool(true)
