   How does ftok work in PHP?

   • Behaviour is like PHPs ftok(), -1 is returned if file is missing or $filename is empty, computed int as hex on success. If you're planning to use ftok() to generate an IPC identifier to share with other applications, note that PHP uses the ASCII value of the proj parameter to generate the key, not the proj (aka id) parameter itself.

   Why does ftok return $key?

   • return $key; The rather unintuitive usage of ftok with shm related functions like shmop_open and shm_attach could simply be explained as a need to avoid shm key collisions. Using ftok with a file that belongs to your project is likely to generate a unique key.

   Why was ftok() not computed like the original Unix ftok()?

   • The key's were NOT computed like the original UNIX ftok() because i.e. fileinode() is also missing on windows. Normally ftok() computes a key based on the file inode and the system minor id of the harddrive the file resides. Behaviour is like PHPs ftok(), -1 is returned if file is missing or $filename is empty, computed int as hex on success.
