Missing STDIN.

Hi.

I've been looking into getting some PHP scripts to be usable as filters ... e.g.

dir | LineReverse

By using ASSOC and FTYPE at the command line to define what .php is and how it is executed, along with having the php.exe in PATH and .PHP in PATHEXT, the script executes, STDIN is always available, but STDIN becomes "blocking" and no output. (See http://docs.php.net/manual/en/install.windows.commandline.php for the documentation I'm working from and currently updating).


But ...

dir | c:\php5\php.exe LineReverse.php

works fine.



I'm hoping someone who knows the way in which windows shells work can answer this.


The registry settings for .php and phpfile are ...

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.php]
@="phpfile"
"Content Type"="application/php"

and

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\phpfile]
@="PHP script"
"EditFlags"=dword:00000000
"BrowserFlags"=dword:00000008
"AlwaysShowExt"=""

[HKEY_CLASSES_ROOT\phpfile\DefaultIcon]
@="C:\\PHP5\\php-win.exe,0"

[HKEY_CLASSES_ROOT\phpfile\shell]
@="Open"

[HKEY_CLASSES_ROOT\phpfile\shell\Open]
@="&Open"

[HKEY_CLASSES_ROOT\phpfile\shell\Open\command]
@="\"C:\\PHP5\\PHP.EXE\" \"%1\" %*"

[HKEY_CLASSES_ROOT\phpfile\shell\Open\ddeexec]

[HKEY_CLASSES_ROOT\phpfile\shell\Open\ddeexec\Application]
@="PHP"

[HKEY_CLASSES_ROOT\phpfile\shell\Open\ddeexec\Topic]
@="System"



I'm wondering if there are some additional options I can use here.

A daft example that works ...

dir Z:\*.txt | find /i ".txt" | php z:\filter.php  | sort /r

outputs ...

dir Z:\*.txt | find /i ".txt" | z:\filter  | sort /r

executes (I can see this via Process Explorer), but nothing I have to CTRL+C to break the task.
