RE: [PHP] upload question

there is no indication what exactly you want to know , its too ambiguous , but all i can say this book sounds like a dud, terrible explanation on file uploads, check out this pear package, it helped a great deal ,although i had to mod it to also do a check for mimetypes , as say i allowed only the extension types of jpg , or zip , i could rename an executable file to a jpg or zip and maybe it could be executed , anyway i had to mod it to also do a mime types allow check but anyway check it out http://pear.php.net/package-info.php?pacid=20 also do a print_r($_FILES); this will show u what you may need to know
