Perl coding to PHP coding conversion
- by Haskella
Hi, I am trying to convert some Perl into PHP using this guideline:
http://www.cs.wcupa.edu/~rkline/perl2php/#basedir
Basically I know next to nothing about these two languages. Please give me some simple English explanation of what each line does, I'll be more than happy. Thanks for reading :D
Perl CGI program:
#!/usr/bin/perl -T
use strict;
use warnings;
use CGI ();
my %fruit_codes = (
apple => '2321.html',
banana => '1234.html',
coconut => '8889.html',
);
my $c = CGI->new;
my $fruit_parameter = $c->param('fruit_name');
my $iframe_document;
if (defined $fruit_parameter and exists $fruit_codes{$fruit_parameter}) {
$iframe_document = $fruit_codes{$fruit_parameter};
} else {
$iframe_document = 'sorry-no-such-fruit.html';
}
$c->header('application/xhtml+xml');
print <<"END_OF_HTML";
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

</form>
<iframe src="$iframe_document">

</iframe>
</body>
</html>
END_OF_HTML
