          Constructor. Parameters   string $script The PHP script to run (as a string)   string|null $cwd The working directory or null to use the working dir of the current PHP process   array $env The environment variables or null to use the same environment as the current PHP process   int|float|null $timeout The timeout in seconds or null to disable   array $options An array of options for proc_open

                                int
    run(callable|null $callback = null)
          Runs the process. The callback receives the type of output (out or err) and some bytes from the output in real-time. It allows to have feedback from the independent process during execution. The STDOUT and STDERR are also available after the process is finished via the getOutput() and getErrorOutput() methods. Parameters   callable|null $callback A PHP callback to run whenever there is some output available on STDOUT or STDERR   Return Value   int The exit status code   Exceptions   RuntimeException When process can't be launched   RuntimeException When process stopped after receiving signal   LogicException In case a callback is provided and output has been disabled    Process
    mustRun(callable $callback = null)
          Runs the process. This is identical to run() except that an exception is thrown if the process exits with a non-zero exit code. Parameters   callable $callback    Return Value   Process    Exceptions   RuntimeException if PHP was compiled with --enable-sigchild and the enhanced sigchild compatibility mode is not enabled   ProcessFailedException if the process didn't terminate successfully                         
    start(callable $callback = null)
          Starts the process and returns after writing the input to STDIN. This method blocks until all STDIN data is sent to the process then it returns while the process runs in the background. The termination of the process can be awaited with wait(). The callback receives the type of output (out or err) and some bytes from the output in real-time while writing the standard input to the process. It allows to have feedback from the independent process during execution. If there is no callback passed, the wait() method can be called with true as a second parameter then the callback will get all data occurred in (and since) the start call. Parameters   callable $callback A PHP callback to run whenever there is some output available on STDOUT or STDERR   Exceptions   RuntimeException When process can't be launched   RuntimeException When process is already running   LogicException In case a callback is provided and output has been disabled    Process
    restart(callable $callback = null)

Parameters   callable $callback A PHP callback to run whenever there is some output available on STDOUT or STDERR   Return Value   Process The new process   Exceptions   RuntimeException When process can't be launched   RuntimeException When process is already running   See also   start()                          int
    wait(callable $callback = null)
          Waits for the process to terminate. The callback receives the type of output (out or err) and some bytes from the output in real-time while writing the standard input to the process.
