How is it possible that the file locked with exclusive lock can be opened by another call to fopen in the same script? Am i getting it all wrong, or the second call to fopen in the next code should fail? $fp=fopen("somefile", "w"); flock($fp, LOCK_EX); $fp1=fopen("somefile", "w"); I'm using php 4.1.2 windows version on apache 1.2.23.
