Question

Answer 1

+5 A:

You are fetching a JavaScript snippet that is supposed to be built in directly into the document, not queried by a script. The code inside is JavaScript.

You could pull out the code using a regular expression, but I would advise against it. First, it's probably not legal to do. Second, the format of the data they serve can change any time, breaking your script.

I think you should take at their RSS feed. You can parse that programmatically way easier than the JavaScript.

Check out this question on how to do that: Best way to parse RSS/Atom feeds with PHP

Hi, Thanks for your reply but i want to know if i use their rss feed how can i pick the pun of the day dynamically (it should not repeat if i click on refresh)

I think reading the RSS feed, and displaying only the first item should do the trick!

Pekka 2010-02-01 11:23:22

But i want to display different puns if he click on refresh.

Pankaj Khurana 2010-02-01 11:30:01

That is also easy to achieve by picking a random pun from the RSS feed. It's not possible with the JS solution because it shows only the pun of the day.

I am using this code $xml = simplexml_load_file("http://feeds.feedburner.com/PunOfTheDay");$items = count($xml->channel->item);echo $rand=rand(0,$items-1);$description = $xml->channel->item[$rand]->description;echo str_replace('[Click to Vote!]','',$description)Is this is correct approach

I don't know, I can't test it right now. Does it work?

Pekka 2010-02-01 11:48:37

Ya but since the no of puns is less the probability of repetition is very high but thanks for your suggestion

Pankaj Khurana 2010-02-01 12:07:49

Right, I see now! I didn't realize you are fetching a random pun from the Perl script. Sorry! Try talking to them whether there is any way to include more puns to the RSS stream, or serve a random pun through RSS. Otherwise, you may indeed be best off with @Luca Matteis' suggestion.

Answer 2

+2 A:

Pekka's answer is probably the best way of doing this. But anyway here's the regex you might want to use in case you find yourself doing something like this, and can't rely on RSS feeds etc.

document\.write\('      // start tag
([^)]*)                 // the data to match
'\)                     // end tag

EDIT for example:

<?php
$subject = "document.write('&quot;Paying for college is often a matter of in-tuition.&quot;<br />')\ndocument.write('<i>&copy; 1996-2007 <a target=\"_blank\" href=\"http://www.punoftheday.com\"&gt;Pun of the Day.com</a></i><br />')";
$pattern = "/document\.write\('([^)]*)'\)/";
preg_match($pattern, $subject, $matches);
print_r($matches);
?>

hi, can you please elaborate it further

Pankaj Khurana 2010-02-01 11:39:27

@Pankaj: I've edited my answer, I hope that helps.

Luca Matteis 2010-02-01 11:47:34

+1 for answering the question.

Pekka 2010-02-01 11:49:05

Thanks but it is giving Warning: preg_match() [function.preg-match]: Unknown modifier 'g'Removing g gives the correct output.

Pankaj Khurana 2010-02-01 11:51:25

@Pankaj: ok, i guess i forgot how php's regex implementation works
