PHP Error: Function registration failed - duplicate name - curl_init - php

I am using Oracle RightNow which uses the Zend framework. I have the code below in a model.
function getTicketAvailability($id){
\load_curl();
$url = "https://www.eventbriteapi.com/v3/events/".$id."/ticket_classes/?token=XXXXXXXXXXXX";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$body = \curl_exec($ch);
curl_close($ch);
$json = \json_decode($body,true);
return $json["ticket_classes"][0]["on_sale_status"];
}
If I call it once in a page, all is well. If I have to call it twice, I get the following:
Function registration failed - duplicate name - curl_init
I also get the same for curl_copy_handle, curl_version, curl_setopt, curl_setopt_array etc
Any ideas on how to resolve this issue?

As it seems load_curl initializes those functions, so check first if they are existing, if not load it.
if (!function_exists("\curl_init"))
{
\load_curl();
}

Use cURL to call controller in CodeIgniter project

Okay so this problem is bothering me quite a bit.
I've created a controller function in my CodeIgniter projects at [project_url]/admin/orderpicking/get_updated_statuses
function name: get_updated_statuses
controller name: Orderpicking.php
controller location: application/admin
Inside the controller all I have is
ob_start();
print_r('success');
file_put_contents('file.txt', ob_get_contents());
ob_end_clean();
to confirm that I am hitting the controller.
When I hit the controller directly from my browser, the file gets created with 'success' as the content.
When I use cURL from another project to hit the controller, nothing happens, the result is an empty string (I dont care about the result right now, but the file.txt file is no longer being created).
Code that calls the controller is as follows:
$data = array('datetime'=>new DateTime());
$header = array(
'Identification:Portal::ReadAPI', // TODO config
'Content-Type:application/x-www-form-urlencode'
);
$url = '[local instance]/admin/orderpicking/get_updated_statuses'; // TODO config
$curlGetUpdatedItems = curl_init($url);
/** CURL OPTIONS */
curl_setopt($curlGetUpdatedItems, CURLOPT_POST, 1);
curl_setopt($curlGetUpdatedItems, CURLOPT_POSTFIELDS, json_encode(serialize($data)));
curl_setopt($curlGetUpdatedItems, CURLOPT_HTTPHEADER, $header);
curl_setopt($curlGetUpdatedItems, CURLOPT_RETURNTRANSFER, true);
// curl_setopt($curlGetUpdatedItems, CURLOPT_SSL_VERIFYPEER, true);
// curl_setopt($curlGetUpdatedItems, CURLOPT_SSL_VERIFYHOST, 2);
// curl_setopt($curlGetUpdatedItems, CURLOPT_CAINFO, $certificate_location);
/** CURL OPTIONS */
$result = curl_exec($curlGetUpdatedItems);
Are there any obvious mistakes I'm making here?
I will add in a certificate later when I make the portal https but until then I don't think I need it?
Any help and/or advice is extremely welcome!
----- UPDATE -----
After var_dump'ing the result I've noticed that a boolean true is returned.
curl_error($curlGetUpdatedItems) returns an empty string.
you can do it make by steps:
$data_string = http_build_query($data);
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($data));
curl_setopt($ch,CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
$result = json_decode($result,true);
don't know if need the header, i think that the default already is application/x-www-form-urlencode
id it not works, try changing the $data values in array. think helps . :)

why Instagram returns blank to CURL request?

i write following code to get html data from url and its working for https site like Facebook but not working for Instagram only.
Instagram returns the blank
<?php
$url = 'https://www.instagram.com';
$returned_content = get_data($url);
print_r($returned_content)
/* gets the data from a URL */
function get_data($url) {
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
?>
The Instagram will return only javascript, that can't be render by your browser because it uses dynamic path, so <script src='/path/file.js'> will try to get localhost/path/file.js instead of instagram.com/path/file.js and in this situation the localhost/path/file.js not will exist, so the page will be blank.
One solution is find a way to give the full HTML instead of the Javascript, in this case you can use the "User-Agent" to do this trick. You might know that JS not handle by the search-engine, so for this situation the Instagram (and many websites) give the page without JS that is supported by the bot.
So, add this:
curl_setopt($ch, CURLOPT_USERAGENT, "ABACHOBot");
The "ABACHOBot" is one Crawler. In this page you can found many others alternatives, like a "Baiduspider", "BecomeBot"...
You can use "generic" user-agent too, like "bot", "spider", "crawler" and probably will work too.
Here try this on
<?php
$url = 'https://www.instagram.com';
$returned_content = get_data($url);
print_r($returned_content);
/* gets the data from a URL */
function get_data($url) {
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
//Update.................
curl_setopt($ch, CURLOPT_USERAGENT, 'spider');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HEADER, false);
//....................................................
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
?>
You should pass
curl_setopt($ch,CURLOPT_SSL_VERIFYPEER, false)
and other header info as above.

How to make a call to .aspx https from php script from my localhost with xamp?

I am trying to send SMS from my localhost with xamp installed.
Requested page is on https and an .aspx page.
I am getting error: "HTTP Error 400. The request is badly formed." or blank page only in some cases.
Detaisl is as follows :
$url = 'https://www.ismartsms.net/iBulkSMS/HttpWS/SMSDynamicAPI.aspx';
$postArgs = 'UserId='.$username.
'&Password='.$password.
'&MobileNo='.$destination.
'&Message='.$text.
'&PushDateTime='.$PushDateTime.
'&Lang='.$Lang;
function getSslPage($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_REFERER, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$result = curl_exec($ch);
curl_close($ch);
return $result;
}
$response = getSslPage($all);
echo "<pre>";
print_r($response); exit;
I tried every possible solution/combination found on internet but could not resolve that. The API developers do not have a example for php script.
I tried httpful php library and file_get_contents function but getting empty page. Also tried every combination with curl_setup.
I need to call this url without any post data and see the response from it.
Instead getting a blank page.
Please note that when I execute the url with all details in browser it works fine.
Can anybody help me in this regard.
Thank you,
Usman
First do urlencode over your data as follows:
$postArgs = 'UserId='. urlencode($username.
'&Password='.urlencode($password).
'&MobileNo='.urlencode($destination).
'&Message='.urlencode($text).
'&PushDateTime='.urlencode($PushDateTime).
'&Lang='.urlencode($Lang);
After that two possible solutions. One is using GET.
curl_setopt($ch, CURLOPT_URL, $url . "?" . $postArgs);
Second option is using POST method.
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postArgs);

Toggl Reporting API with PHP cURL

I am trying to access the Toggl Reporting API.
I tried following in PHP with cURL, which connects to the API but gives the following error message: 'This method may not be used.' Any light on why this is the case would be useful as I'm very new to webservices. I may be missing something obvious or totally going the wrong way about it, so apologies if this is the case.
<?php
$userAgent = 'xxx';//username
$token = 'xxx';//token
$returned_content = get_data('https://toggl.com/reports/api/v2/summary?&workspace_id=[workspaceid]&since=2013-05-19&until=2013-05-20&user_agent=[username here]');
print_r($returned_content);
function get_data($url) {
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_USERPWD, $token.':api_token');
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
?>
Edit: I tried a different approach. If I run the following code, I no longer receive any error messages, so the code seems to be executing but I can't print the response to the screen. Is there something specific I need to do to view the output other than print_r?(Toggl API returns JSON). Thanks.
$json = curl%20-v%20-u%[myapitoken]:api_token%20https://toggl.com/reports/api/v2/weekly?workspace_id=[id]&wsid=282507&since=2012-08-19&until=2013-09-20&user_agent=[user].json;
print_r($json);
Edit: Finally resolved! Code is as follows:
$workspace_id = '[id here]';
$user_agent = '[user agent here]'; // no spaces
$api_token = '[token here]';
$report_url = 'https://toggl.com/reports/api/v2/weekly?user_agent='.$user_agent.'&since=2013-08-01&until=2013-09-01';
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
curl_setopt($ch, CURLOPT_USERPWD, $api_token . ':api_token');
curl_setopt($ch, CURLOPT_URL, $report_url . '&workspace_id=' . $workspace_id);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$result = curl_exec($ch);
$result = json_encode($result);
Hope this helps someone in the future!
As I understand, you are receiving this message because of CURLOPT_SSL_VERIFYPEER == FALSE.
Try to remove this string from the code:
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
Maybe I wrong, but I think with this option you are receiving "HTTP 501 Not Implemented" error from the Toggl server, which contains exactly the same message, "This method may not be used."

CURL not working when used inside a function

I'm trying to execute curl using the following code.
mainFunction{
.
.
$url = strtolower($request->get('url', NULL));
$html_output= $this->startURLCheck($url);
.
.
}
function startURLCheck($url)
{
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$html_output = curl_exec($ch);
}
When i give the string URL directly this is working fine. But then I pass the string data through a function curl is not executing. curl_error gives shows no errors too. I tried many encoding and decoding method for the string with same result.Am i doing something wrong? I working using XAMPP server on windows.
I'm passing URL to this function after getting the URL from a HTML post request in another function.
The problem is that your function startURLCheck does not actually return a value for the main program to use. Change the last line:
function startURLCheck($url)
{
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
return curl_exec($ch);
}
In your calling code, take out the "$this->"
$html_output = startURLCheck($url);
$html_output now contains results of the curl call.
I have assumed that you copied and pasted this code from somewhere since your "mainFunction" declaration is syntactically incorrect, and you used "$this->" without specifying that startURLCheck was a method of an object.
If in fact you intend startURLCheck to be an object method and you want it to set $html_output on the object, do this:
<?php
class Example {
private $html_output;
function mainFunction()
{
$url='http://www.ebay.com/itm/Apple-iPhone-5-16GB-Black-Slate-Cricket-intl-UNLOCKED-pleeze-read-ad-/251252227033';
$this->startURLCheck($url);
echo "HTML output: " . $this->html_output;
}
function startURLCheck($url)
{
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$this->html_output = curl_exec($ch);
}
}
$example = new Example();
$example->mainFunction();
I have tested this code on the command line (not in a web page). If you copy and paste this into a file and run it using php -r you will see the results. (And note that I didn't include a closing ?> tag. The closing tag is optional when the file contains only PHP code and no HTML. In fact it is recommended that the closing tag be omitted in such cases. See http://php.net/manual/en/language.basic-syntax.instruction-separation.php)
Please also note in your question code for mainFunction you have illegal spaces before "pleeze" in your URL and you are missing the semicolon at the end of the $url assignment.
Hope this helps. Good luck.
This works good.
<?php
function excURL()
{
$ch = curl_init();
$url = "http://www.google.com";
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
$html_output = curl_exec($ch);
echo $html_output;
}
excURL();
?>
Hey Guys I have found the problem..Finally..
When I set CURLOPT_FOLLOWLOCATION for the curl this is working fine...
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
But stil it is not clear why it worked when I hardcoded the URL inside the function and did not work when I passed url as a variable into the function, without setting CURLOPT_FOLLOWLOCATION ... When I set this option it is working in both ways..
