Bug #53518 [NEW]: pclose and proc_close do not return values for use with pcntl_wifexited

From: Operating system: Linux PHP version: 5.3SVN-2010-12-10 (SVN) Package: Program Execution Bug Type: Bug Bug description:pclose and proc_close do not return values for use with pcntl_wifexited Description: ------------ The manual for pclose and proc_close states: Note: Unix Only: proc_close() is internally implemented using the waitpid(3) system call. To obtain the real exit status code the pcntl_wexitstatus() function should be used. However, they in fact return the real exit code directly. This makes it impossible to tell whether a program exited normally or was killed by a signal.
