[Resolved] help with preg_match()

[pjleonhardt]

I'm having a little trouble with preg_match(). It's been quite some time since I've last used it. I've looked at the manual and googled it a bit, but I can't quite seem to find what I'm looking for.

The problem is this:
I'm calling an amazon page, and then trying to look up the price of the item displayed on the page.

<?php

$handle = 'http://www.amazon.com/exec/obidos/tg/detail/-/B0001DI6FM/qid%3D1099160907/sr%3D1-3/ref%3Dsr%5F1%5F3/002-5300324-7261602?v=glance&s=videogames';

$html = file_get_contents($handle, 1056784);

preg_match_all('/<b class="price">\n$(.*)/U', $html, $match) or die('error');

print_r($match[0]);

When I use the above it will return "error".. If I chance it to just "/<b class="price">(.*)/U"

it returns
Array
(
[0] => <b class="price">
)

The code on the page that I'm looking to match is:

<b class="price">
$45.95
</b>

Any suggestions?

the $ would only match line ends with the m (multiline) modifier set - it still may not work because of the \n before it, and I'm not sure that this is what you need anyway.

check the second pattern but with the s (dotall) modifier set, it probably failed because the dot doesn't match newlines by default.

Thanks, with your help I figured it out..

I ended up using

preg_match_all('|<b class="price">\n(.*)\n</b>|', $html, $match);

When I used the s modifier it took the entire page after the </b> as well, which I didnt want. But it let me realize that I needed to put an extra \n between the (.*) and the </b>.
