can use flock but not funlock

[hinchdog]

i'm trying to lock and unlock a file for editing using the flock and unflock functions. i can use flock fine (ie. flock($fp, 1) but when i try to use funlock($fp); i get a function undefined. does this have to do with a bad php install on my webhost or am i missing something?

What version of PHP are you using?

 

[Hokey]

If it is 4.01

lock: flock($fp,1); // or 2 for exclusive (writer)
unlock: flock($fp,3);


If post 4.01

lock: flock($fp,LOCK_SH); // or LOCK_EX for exclusive (wirter)
unlock: flock($fp,LOCK_UN);

Hope this helps
