[ale] simple PHP question on proc_open

[Jerry Yu]

Thanks, Jay.  Once I changed it from 'file' to 'pipe', it runs w/o problem.
Now to think of it, the error is somewhat troubling, since $descriptors
array actually changed to command to be executed?!
The wordpress plugin was an old one. So, the 'file' type obviously was ok
for PHP 4.3 (CentOS 4.4), but is not ok for PHP 5 (FC6)
