Question

Which function is used to determine whether a file was uploaded?

(a) is_file_uploaded()

(b) is_uploaded_file()

(c) file_uploaded(“filename”)

(d) uploaded_file(“filename”)

This question was addressed to me in semester exam.

My question is based upon Uploading Files with PHP in division File and Session Handling in PHP of PHP

Answer 1

The correct answer is (b) is_uploaded_file()

The best I can explain: The function is_uploaded_file() checks whether the specified file is uploaded via HTTP POST. The syntax is is_uploaded_file(file).
