Get file content via PHP cURL

Question 1

I have an website. Let's call it http://www.domain.com. Now, on this domain.com I want to display the file contents of http://www.adserversite.com/ads.php. How can I do that with cURL or another method? I don't want to use iframe.

Thanks

Question 2

echo file_get_contents('http://www.adserversite.com/ads.php');

Who needs curl for this simple task?

Question 3

Depending on your PHP configuration, this may be a easy as using:

$jsonData = json_decode(file_get_contents('https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello|World&chof=json'));

However, if allow_url_fopen isn't enabled on your system, you could read the data via CURL as follows:

<?php
    $curlSession = curl_init();
    curl_setopt($curlSession, CURLOPT_URL, 'https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello|World&chof=json');
    curl_setopt($curlSession, CURLOPT_BINARYTRANSFER, true);
    curl_setopt($curlSession, CURLOPT_RETURNTRANSFER, true);

    $jsonData = json_decode(curl_exec($curlSession));
    curl_close($curlSession);
?>

Incidentally, if you just want the raw JSON data, then simply remove the json_decode.

Question 4

You should only call curl_close() when you know you're done with that particular handle, or if switching from its current state to a new one (ie: changing a ton of options via curl_setopt() would be faster by going from a clean new handle than your current "dirty" one.

The cookiejar/file options are only strictly necessary for maintaining cookies between seperate curl handles/invokations. Each one's independent of the others, so the cookie files are the only way to share between them.

Question 5

This information is not sent in the HTML code, but in the HTTP headers. If the curl_getinfo call does not return it, the server did not send it in its HTTP headers.

Question 6

What URL are you trying to load? It could be that the page you're requesting has one or more AJAX requests that load content in after the fact. I don't think that cURL can accomodate runtime-loaded information via AJAX or other XHR request.

You might want to look at something like PhantomJS, which is a headless WebKit browser which will execute the page fully and return the dynamically assembled DOM.
