Jenn, as much as I would like to say I didn’t I did. I wrote the whole thing on my PC in an editor and tested each line, pasted it into WordPress and clicked on Save. WordPress then removed a lot of the work I put in including breaking the code. I apologize for not catching all of them, but it is hard to really get it to work when the only one who can post such symbols and characters is the WordPress Admin.

I am going to assume the original article was missing them due to WordPress as well, but that is an assumption. Guess I won’t really know.

If you find any other mistakes I apologize in advance, but my original article on my PC did not have any of these…

You’re still missing quotes around the replacement string in #16. Yes, they’re missing in the original post on assembleron.com too.

There’s no way to say this without sounding b—-y, but you should really try actually running any code that you post… it saves people like me precious nagging time

Ok, sorry, see if that’s better now…

Actually, I meant to mess things up, I was checking to see who was paying attention and besides it got some of you people to comment

Thanks Jenn and Fred for your feedback!

Sorry guys, my code did get rip to shreds. WordPress sucks when pasting code, I apologize.

I’ll try to get Mark to correct it for me when he gets a chance.

Thanks,
Matt

Also, for 17, I think your intent here might have been a regex like /\<(.*?)\>/. This will get the job done, but if you’re gonna use preg_replace, a better alternative would be /(<[^>]*>)/ (not sure if we need to backslash the tag wrappers).

Its just a more efficient match. The basic idea here is 1) match the opening delimiter, 2) match text which is not the closing delimiter, 3) match the closing delimiter.

16 (as posted, maybe it contains a typo) will actually divide the numeric results of the regex since the result regex is not quote encapsulated. I think the fp value is something like 0.001622566. I would say this is a bug, and not the intended use of the function.

16. Actually it does nothing because it’s riddled with errors…

17. I think the code you wrote is getting eaten by the browser. It doesn’t even really make sense and just throws a warning.

More about regular expressions...

Thanks MrSpooky,

I have it corrected, once you stated the percent sign I was like “OMG! I didn’t screw that up…” But I did, and you caught it.

As for the associative array, that is true, but I just stuck to the question denoting the way the two languages distinguish between arrays and hashes, not necessarily their indexes, but it was nice of you to mention it.

By: MrSpooky

MrSpooky — Mon, 27 Aug 2007 17:15:30 +0000

Actually, hashes in perl start with a percent (%) sign

%hash = {};

# is what you use to comment lines out

Another difference is the indices in a PHP associative array use brackets like regular arrays, however perl uses curly braces:

$hash{‘key’};
