Was the file uploaded by php also? Part of the same script? – nospi Apr 11 '17 at 07:24
that means you need to change folder permission to 077 and files permission to 644 – Alive to die - Anant Apr 11 '17 at 07:24

All permission are given. My problem is i couldn't unlink only recently uploaded file. – saron Apr 11 '17 at 07:32
Can you share your code please. – Twinfriends Apr 11 '17 at 07:35
It passed the file_exists and is_file conditions. – saron Apr 11 '17 at 07:38
what is your platform? is it windows or linux? on windows you cannot remove opened file. – Znik Apr 11 '17 at 07:49

Windows.No files are opened. @Znik – saron Apr 11 '17 at 07:52
@saron Have you ensured sufficient permissions are set ? – Vaishal Patel Apr 11 '17 at 07:58
if uploader is the same process that deletor, then maybe system is unable to really close file on time, when you want delete it. ("thank you" Alive to Die, I won't make real answer because your minus.) . You can do some debug, before your move/unlink procedure insert some sleep, and check file is really not opened. Symptoms points, it is a chance file is still opened or semi closed. But you can do workaround. You can rename file adding suffix .todelete , and in next call try unlink all *.undelete files . – Znik Apr 11 '17 at 08:08
