file_get_contents and div

Question

What's wrong with my code? I wish to get all dates from but my array is empty.

<?php
$url = "http://weather.yahoo.com/";
$page_all = file_get_contents($url); 

preg_match_all('#<div id="myLocContainer">(.*)</div>#', $page_all, $div_array);

echo "<pre>";
print_r($div_array);
echo "</pre>";
?>

Thanks

It might be your code, it might be not. Please provide more debug otherwise you'll waste others time in wild goose chases. — zaf, Jul 04 '10 at 16:33

You want to parse a multiline content but you did not use multiline switch of REGEX pattern. Try using this:

preg_match_all('#<div id="myLocContainer">(.*?)</div>#sim', $page_all, $div_array);

Please note that regular expressions is not suitable for parsing HTML content because of the hierachical nature of HTML documents.

try adding "m" and "s" modifiers, new lines might be in the div you need.. like this:

preg_match_all('#<div id="myLocContainer">(.*)</div>#ms', $page_all, $div_array);

Before messing around with REGEX, try HTML Scraping. This HTML Scraping in Php might give some ideas on how to do it in a more elegant and (possibly) faster way.

There is a recent implementation of such a library (allowing to access elements via CSS etc) built on PHP 5.3, using some components of the upcoming Symfony 2. Note: It's still kind of unstable. http://www.phparch.com/2010/04/22/four-new-php-5-3-components-and-goutte-a-simple-web-scraper/ – igorw Jul 05 '10 at 10:32

$doc = new DomDocument;
$doc->Load('http://weather.yahoo.com/');
$doc->getElementById('myLocContainer');

you need to Excape Special Characters in your Regular Expression like the following

~\<div id\=\"myLocContainer\"\>(.*)\<\/div\>~

also Checkout wheather there is a newline problem or not as mentioned by @eyazici and @kgb

Test your response before running the regex search. Then you'll know which part isn't working.

file_get_contents can use a http stream wrapper, so it's not only for local files – Sergey Eremin Jul 04 '10 at 16:33
