php and perl

[Anon]

Hi,

I am trying to have php actuate a perl script, capture the output, and echo that back to the screen. Anyone have any ideas on how to implement this kind of thing.

Thank in advance,

A kind person sent me the following code. I have not tried yet !
Please let me know if you have found an easier way.

The PERL program is called "PERL_prg" and needed several input
variables from my PHP script.

** Step 1.) I concatenated all PHP variables into a string:
$input_word. Variables were separated by blanks
(e.g. $input_word = "var1 var2 var3")

**Step 2.) I wrote a small PERL program called callcp.pl which
makes the interface between PHP and PERL (see step 3).
This PERL program is called from the PHP script in the following
way:

  $input = "perl perl/callcp.pl " . $input_word;
  exec($input,&$PERLout,&$status);

$PERLout will be the output variables calculated by the PERL
program PERL_prg.

**Step 3.) The interface prg. "callcp.pl" first transferred the PHP
input parameters into an array PerlParams, which could be used
by the PERL program. It then called PERL_prg, calculated
something which was returned in "result".
--> Now the important thing to get the PERL variables back to
PHP: you have to include the print statement at the end of callcp.pl.

I hope this helps.
Good luck
Julia

---------callcp.pl-------
my(@PerlParams);

for ($i=0; $i <= $#ARGV; $i++) {
push(@PerlParams, $ARGV[$i]);
}

my @result = &PERL_prg(@PerlParams);

#..write result to output file
for(@result)
{
print "$_\n";
}
