Calling perl script from PHP

[rahulthathoo]

Hi.

I need to develop a web based application which uses php for the front
end and statistical manipulations in perl - my question is - how do i
call a perl script from php - i guess the answer is gonna be exec. I
cant seem to understand how can i pass variables from the PHP script
to the Perl script and vice versa using exec? Is there a better way to
go about it?

Apart from this, another question that I had was - once the perl
script is done running - and has completed successfully, how do i know
in the php script that this has happened - coz i need to do something
the moment it(perl script) finished exection?

You could store all your variables in one big array, serialize() the
array, and then pass it to Perl as STDIN. In Perl, you can then use Scott
Hurring's implementation[1] of unserialize() to retrieve the data.

Passing data back, again, in Perl bundle the data up into a Perl hash,
serialize() it using Hurring's module, and then print it to STDOUT. PHP
reads the STDOUT and unserializes the data.

Easy peasy.

Ah, that's very cool. That's a very clever way to communicate data. :)
