curl_init和curl_exec：提取表？

Question

hey guys, i'm completely new to cURL - i've never used it before. If i paste the following two lines inside of my sidebar ...

<?php
    $objCUrl = curl_init("http://www.domain.com/hptool/weather_v1.php?cid=43X1351&l=en");
    curl_exec($objCUrl);
?>

...i get two divs and a table inserted into my page. Is there a method where i can kind of inspect everything that gets loaded with this curl_init function? I just want to get specific stuff on my page inserted and not everything? E.g. i only want to insert the table but not the two divs that get inserted into my page.

I know i could simply hide them with css, but i'm just curious.

Save the result to a string instead of outputting it.

$url = 'http://www.domain.com/hptool/weather_v1.php?cid=43X1351&l=en';

$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HEADER, false);

$str = curl_exec($curl);

Now you can pull whatever you need out of $str and display that.

First place you should go is the documentation for how to use a function/library.
