PHP Bug Type: Program Execution
Bug description: exec(): Problem with quotes in commandline
Description:
------------
If i have a complicated commandline with quotes and spaces in it, and pass
it to exec(), system(), ..., then i get under Windows "path or filename not
found" despite the filenames are correct.
The Problem is the following:
PHP starts a command over the command-interpreter by prefixing the
commandline with "cmd.exe /c ".
Test in DOS-Box:
If I enter the command in a "DOS-Box", the result is ok, but if I prefix
it with "cmd.exe /c ", then i get the same failure as in PHP.
If you read the "manpage" ("cmd.exe /?"), there is a hint, that "cmd.exe
/c" has problems with quotes. And IMHO there is no way to escape theese
quotes.
My solutions are:
- Someone finds a way to escape quotes for cmd.exe
- A new Parameter for system()/exec()/...
- ... or better: A php.ini-setting, ... which controls, if the command is
executed over the shell, or executed directly.
Reproduce code:
---------------
system('"D:\Program Files\fop\fop.bat" "path with blanks/to/bla.fo"
"output path/bla.pdf"');
Expected result:
----------------
Successful execution.
Actual result:
--------------
cmd.exe says: "path/file not found"
