Question

I normally call perl scripts from PHP as below and pass in variables this way, and it works fine, however now I am building a component for re-use where I want to also varia

Answer 1

Your way is not working because you are concatenating all the parameters without spaces, effectively making them one parameter.

Try

$perlscript_file = "/var/www/other_scripts/perl/apps/$perlscript.pl $var1 $var2 $var3 $var4";

By the way, if the parameters are coming from an external source, you MUST sanitize them using escapeshellarg(). The same goes for $perlscript - if it comes from an external source or even user input, do a escapeshellcmd() on it.
