Can't delete a file in PHP

Question

I can't delete a file using unlink() and when I use fopen with the "w" tag, I get an error. The file has 777 chmod. I can use fopen() to write at the end of the file. But I can't delete anything. Can anybody help me please?

Here's a sample:

   echo substr(sprintf('%o', fileperms('..')), -4); //777
   echo substr(sprintf('%o', fileperms('.')), -4); //777
   echo substr(sprintf('%o', fileperms('test')), -4); //777
   chmod('tmp',0777);  //Permission denied

To unlink a file, you need write permission on the directory it's in. Having the file itself chmod'd 777 won't help

I've run into this issue before and been able to remedy by forcing garbage collection after closing the file and before unlinking it:

gc_collect_cycles();

By far not the best solution, but it did resolve an issue I had deleting files that had been previously opened and closed lines before.
