Hi,

Please anyone tell me what is the difference between the functions unlink and unset?

#programming #php #unlink #unset

People who post questions that clearly have done no research should have their sig link removed. If you posted that question into google instead you would have received an answer much easier... but then you wouldn't get your sig link exposure...

  Plus here we have sockpuppets with identical sigs used strictly to double the "conversation".

unlink - Deletes a File (http://www.php.net/unlink)
unset - Destroys a Variable (http://www.php.net/unset)

PHP.net is your buddy.

  you can only unlink a file that's owned by the process php is running as. if php is run as nobody (apache user) and the file is not owned by nobody youll get a permission denied error also some hosts might disable unlink.

unlink = deletes a file

  No, use rmdir for that.
