Hi Roy and Olav,
Sorry for the delay in responding! I left for a photo shoot at the
beach Thursday morning, was swamped when I got home and checked email
Saturday, and then the server hosting three of my domains failed, so
it has been busy and then rough few days. (yeah, the photographing a
beautiful model on the beach part wasn't so bad ;-)
Actually, what I was trying to do was come up with a way of, under
the Windows XP Pro command line, doing what is so easy to do under
MPE in a batch job.
I guess an over-simplification would be to say that I wanted to do
the equivalent of the following in a Windows .bat file, but it can't be done:
!job jobname,username/pass.acctname/pass
!run php.php;info="phpscriptname"
first_line_of_data_for_php_script
second_line_of_data_for_php_script
...
last_line_of_data_for_php_script
!run php.php;info="phpscriptname"
first_line_of_data_for_php_script
second_line_of_data_for_php_script
...
last_line_of_data_for_php_script
!run php.php;info="phpscriptname"
... etc.
!eoj
I received some private replys that basically said "not possible with
the Windows command line interpreter."
Thus, I wrote a little PHP script that reads a "batch file" of my own
format, which looks sort of like:
!php php_script_name
first_line_of_data_for_php_script
second_line_of_data_for_php_script
...
last_line_of_data_for_php_script
!php php_script_name
first_line_of_data_for_php_script
second_line_of_data_for_php_script
...
last_line_of_data_for_php_script
!php php_script_name
first_line_of_data_for_php_script
second_line_of_data_for_php_script
...
last_line_of_data_for_php_script
!eoj
Look familiar? (LOL)
It works by always reading at least one line ahead of where it is
executing. If the line following the "!php" line does NOT start with
"!" then it creates a temp file, copies the line it just read and all
line which follow up to the next line that starts with a "!" into the
temp file. When it sees a line that starts with a "!" it closes the
temp file, then creates a command string for the Windows CLI that
specifies the just-created temp file as the Stdin, and has the system
statement execute the command. When the system statement completes,
it looks in the buffer to see if the line in the buffer (which
started with "!" is a valid command (of which "php" and "eoj" are the
only two valid commands at present). If the command is other "eoj"
then it terminate, otherwise the process repeats.
Anyway, that was my solution. And one of the reasons I like PHP - it
runs on almost every platform. Now all PHP needs is access to Tk on
Windows (like Perl has)!
Thanks All!
