I don't see a need to add an option. Regarding the original
report, the solution would be to enclose the command in another
pair of double-quotes, e.g.
system('""D:\Program Files\fop\fop.bat" "path with blanks/to/bla.fo"
"output path/bla.pdf""');
As of PHP 5.3.11, this additional pair of double-quotes is
inserted by PHP, so the original test script should work as is.

Since PHP 5.2.1 the proc_open() function has a new parameter "bypass_shell", which is the
needed feature.
It would be nice to have the same solution for all other shell related functions
(exec,shell_exec,system,...). For example via a php.ini option.

cmd.exe /C accepts only two quotes in a commandline. If there are more, then the first and the last
quote is removed.
This makes it impossible to pass commandlines like:
"C:/Program Files/bla/bla.exe" "c:/my files/bla.txt"
So it is IMHO the best way, if we create an option to bypass the command-interpreter.

I have the same problem. I have also no solution to execute commands with many quotes.

Sure, it's not directly a Bug in PHP, but it's a feature-request to workaround a
bug/feature of cmd.exe:
We need a possibility to bypass the command-interpreter for execution of commands, since cmd.exe
can't execute it complete correctly.
Or someone finds a solution to escape quotes correctly. I will check this out over the weekend ;-)

Sorry, but your problem does not imply a bug in PHP itself. For a

appropriate forum for asking support questions. Due to the volume
of reports we can not explain in detail here why your report is not
a bug. The support channels will be able to provide an explanation
for you.
Thank you for your interest in PHP.
