Somewhere between 4.1.1 and 4.2.3, the return value from pclose changed.



The exit status used to be in the second byte, so that the status would be (pclose($fp)/256).



It is now in the low-order byte, so the status is just pclose($fp).



Be careful.

As I understand pclose will return 0 (on every platform) in case popen could not execute the specified command.



Since popen only returns the status wether it was able to send a command and not wether it was succesfully executed. Only the returned value of pclose can be used to check wether a command could be executed.

The return value of pclose() is not the exit status of the program, but a value as returned by waitpid() of wait4().





To obtain the exit status:





$ret=(pclose($f)>>8)&0xFF;
