Re^5: Size of a HASH (with more keys)

The best solution would be using a JSON module. :)

The second best is to push @lines, "JSON ENTRY" within the loop, and then to print join ",\n", @lines after the loop.

See join for details.

HTH! :)

Re^6: Size of a HASH (with more keys) by David92 (Sexton) on Jul 02, 2014 at 14:12 UTC
I am trying to find a step by step guide on how to do the JSON encode using CPAN's module. In their library I know it's descriptive. But I as I read it quickly, I think they generate only JSON (which is a bit different than JSONP). Nevertheless, so If I have a HASH where all the info is stored that I want. How should I create a JSONP with this Module? `$json_text = $json->encode( $perl_scalar );` This is the syntax from CPAN. Is the $perl_scalar my $testHASH in our case?	[reply] [d/l]
