Integrating Perl with PHP
Yes, it is possible to integrate Perl Interpreter with PHP script. Perl and PHP are very popular web programming Language. Both the interpreter are developed in C language libraries.
Before Integrating make sure that you must install PHP and Perl language.
To check that, open the terminal,
shell> perl -v
It will check the Perl language version along with Perl description and copyright. Likewise,
shell> php -v
It will show the PHP language version along with Copyright and zend technologies group.
For integrating , you must install the PHP Perl extension package. You can download this PHP Perl extension package from this link,
http://pecl.php.net/package/perl
Follow the steps given in README file in the downloaded package.
Through Perl extension package, the programmer can
* load and execute perl files
* evaluate perl code
* access perl variables
* call perl functions
* instantiate perl objects
* access properties of perl objects
* call methods of perl objects
These features can be accessible only through API class called Perl().
For Example test.php :
echo "first line";
$perl_obj = new Perl(); // Creating a object called $perl_obj for the class Perl()
$perl_obj->require("perl_script_file.pl"); // Perl files can be loaded through Perl::require module.
echo "last line";
