I curl_exec a curl_init
I want to make some alterations in the source code of the initialised curl session.(in PHP,JAVASCRIPT or ANYthing else)
Anybody got any idea?
Please help
Try this code out:
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, "http://stackoverflow.com/questions/8936870/how-to-change-the-html-source-code-after-calling-a-curl-init");
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_AUTOREFERER, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$html = curl_exec($curl); // run CURL
curl_close($curl);
echo $html; // and finally, return $html
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
This will return the html code, and after that you can use another function to change this like: str_replace or preg_replace

I'm sending data using cURL on the following code block:
$content = $data['email'].'|'.$data['limit'].'|'.$data['docs'];
$curl = curl_init(ACCESS_URL);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_POSTFIELDS, $content);
$answer = curl_exec($curl);
curl_close($curl);
The webservice side do run and creates the file, but $_POST is empty. I just can't figure out why.
public function action_getAccess() {
file_put_contents('/home/donut/uploads/data.txt', $_POST);
}
From curl:
curl_setopt($curl, CURLOPT_HTTPHEADER, array("Content-Type: text/plain"));
And catch this as:
file_put_contents('/home/donut/uploads/data.txt', file_get_contents("php://input"));
I have written the following function, which was code I used somewhere else and modified slightly to work as a function (using $url in function parameters):
function curl2str($url) {
$cURL = curl_init($url);
curl_setopt($cURL, CURLOPT_RETURNTRANSFER, true);
curl_setopt($cURL, CURLOPT_CONNECTTIMEOUT, 5);
$data = curl_exec($cURL);
curl_close($cURL);
return $data;
}
I simply want a function to return a URL into a string, for a quick and easy API. The URL I am passing it is valid and works fine when I put it into a browser. I am calling it like so:
<?=curl2str("**valid URL here**");?>
For some reason it is just returning false. What am I doing wrong?
update
When I put this questions URL into as $url, I get a response. But when I use my custom URL, which works fine in the browser, and simply display's a list of files in the directory, I get bool:false.
update 2
It would seem that any domain works fine, apart from the one that I am trying to access. It just so happens that this is a root domain on the same server, I am running this script from a subdomain, but because of basedir_restrictions I cannot access a folder from the subdomain. So I wrote a little php to get the contents of the folder, and output it to the browser as a serialized array (JSON is not installed). But I cannot get a response from this root domain at all. It works fine in the browser, just not in cURL. And everything else works fine in cURL.

Try this code into your function:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
if(curl_errno($ch))
echo 'Curl error: '.curl_error($ch);
curl_close ($ch);
Note: curl_errno($ch); return error number>0 if any error occurs from cURL and use curl_error($ch); to see what is the error from cURL.
I use this function:
function curl($url, $cookie = false, $post = false, $header = false, $follow_location = false, $referer=false,$proxy=false)
{
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FAILONERROR, true);
curl_setopt($ch, CURLOPT_REFERER, $referer);
curl_setopt($ch, CURLOPT_HEADER, $header);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, $follow_location);
if ($cookie) {
curl_setopt ($ch, CURLOPT_COOKIE, $cookie);
}
if ($post) {
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
}
$response = curl_exec ($ch);
curl_close($ch);
return $response;
}
I am trying to decode the JSON at https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&incslude_rts=0&screen_name=microsoft&count=200&exclude_replies=1&contributor_details=0 with json_decode() in PHP (decoding as an associative array, so the second parameter is set to TRUE.
The problem is that it seems to not do anything (no error, warning either). The data contains 200 tweets + some extra data about them. If I fetch only let's say 50 tweets, the json_decode function runs successfully.
So my question is: is json_decode not able to decode large strings?
Edit: my code:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url); // $url is the above mentioned URL
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER,0);
$content = curl_exec($ch);
print_r(json_decode($content,true));
There is something wrong with your cURL I suppose. I just tried the following code with the URL you have provided and works just fine:
$curl = curl_init();
$url = 'https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&incslude_rts=0&screen_name=microsoft&count=200&exclude_replies=1&contributor_details=0';
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_URL, $url);
$content = curl_exec($curl);
var_dump(json_decode($content, true));
Why am I not getting the HTML code when I use PHP curl? This is my code:
// $content = file_get_contents('http://www.datadiary.com/Company/311734/dimsinstituteofhotelmanagement');
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.datadiary.com/Company/311734/dimsinstituteofhotelmanagement');
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_COOKIESESSION, false);
$content = curl_exec($ch);
curl_close($ch);
echo $content;
By default curl_exec sends the response to the output (usually the browser). Set the CURLOPT_RETURNTRANSFER option if you want curl_exec to return the result instead:
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
Relevant manual entries:
http://php.net/curl-exec
http://php.net/curl-setopt
You need to add the option to return the transfer as a string:
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
I'm trying to use cURL to do facebook authentication and here's what I have:
$url = "https://graph.facebook.com/oauth/access_token";
$postString = "?client_id=$client_id&redirect_uri=$redirect_uri&client_secret=$client_secret&code=$code";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_FAILONERROR, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
//curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $postString);
$response = curl_exec($curl);
but every time it just returns false.
I'm pretty new to using cURL so I could be making some beginner mistakes, but I'm confused as to why this isn't working at all.
Any help would be greatly appreciated!
This is probably too obvious and it may be a typo, but:
//curl_setopt($curl, CURLOPT_POST, 1);
Should be uncommented.
Remove the "?" from the beginning of your post string.. that should fix it!
