The odds are good that this is code from a module that has, somewhere, the line `use CGI;`.. check out the documentation on the CGI module. If this is the case, and `$query` is a CGI object (look for `my $query = new CGI;` or something similar in your code) then this line is taking a web form parameter called `'fungsi1'`. Of course I could be wrong..	[reply] [d/l] [select]

Without further context, monarch's guess is a good one. About all that can be said with certainty is that the snippet you provided follows this general format: `$variable = $object->method(parameter);` [download] In other words, you are running the method called param() of the object called $query using the parameter named 'fungsi1' and assigning the results to the variable called $fungsi1.

If you need to work with a database and you were hoping that that's what "query" here meant (as opposed to probably being CGI-related as monarch suggester), then take a look at the Tutorials in the database section (especially Before asking a database related question ...)	[reply]

There are a few ways to explain this, as you didn't provide much detail. One short example could be: `use CGI; use strict; use warnings; my $query = new CGI({fungsil=>"123", foo=>"bar"}); print $query->param('fungsil'), "\n"; print $query->param('foo');` [download] This will print: `123 #the value for parameter fungsil bar` [download]	[reply] [d/l] [select]

$fungsi1 = $query->param('fungsi1');
