Curl returns no data (NULL) PHP - php

Very simple code in PHP, that looks like this:
curl_setopt($ch, CURLOPT_URL, "http://[heres url]");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('keycode: [heres keycode]'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
var_dump(json_decode($output, true));
// echo $output; doesn't work as well
[heres url], [heres keycode] - url and keycode are correct
If I run the same script in a app (for example I am using a chrome app named Advanced REST Client) - everything works.
In my PHP script the result is either empty or NULL.
What could be the problem? Thanks.


$url='https://randomuser.me/api/';
$ch = curl_init();
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_VERBOSE, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION , 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPHEADER,array('keycode: [here value]'));
curl_setopt($ch, CURLOPT_URL,$url);
$html = curl_exec($ch);
var_dump(json_decode($html, true));

cURL follow .ASP Link gets 404

I have the following small cURL PHP Script which has to follow an ASP link:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://partners.webmasterplan.com/click.asp?ref=<ID>&site=14910&type=text&tnb=2');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_COOKIESESSION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie_jar.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie_jar.txt');
$page= curl_exec($ch);
curl_close($ch);
?>
But I only get:
The requested URL /click4.aspx was not found on this server.
Has anybody got an idea as to what am I doing wrong?

How to api integeration in core php

I had the payment integration with paywithcapure. They send the sample code for test i used that code its 404 error.
$xml_data2 = 'merchantid=somevalue&token=somevalue&bvn=somevalue';
$URL = "http://flutterwavestaging.com:8080/FlutterwaveRecurringPayments/services/flwcardrecurring/VerifyBvn";
$ch = curl_init($URL);
//curl_setopt($ch, CURLOPT_MUTE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content type - application/x-www-urlencoded'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_data2);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);

First make sure that url is working fine.Paste your url in browser and see the result.If it's not working then contact them for correct url and if its working fine then try this code :
$xml_data2 = 'merchantid=somevalue&token=somevalue&bvn=somevalue';
$URL = "http://flutterwavestaging.com:8080/FlutterwaveRecurringPayments/services/flwcardrecurring/VerifyBvn";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $URL); // you've missed this one.
//curl_setopt($ch, CURLOPT_MUTE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content type - application/x-www-urlencoded'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_data2);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($ch);

cURL XML Post issue

Im posting some XML to a webservice, the code I have written works in all other cases just not in this instance.
This is my code;
$ch = curl_init();
curl_setopt($ch, CURLOPT_POSTFIELDS, $string);
curl_setopt($ch, CURLOPT_ENCODING,'gzip');
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 45);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_FRESH_CONNECT, 1);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: text/xml"));
$result = curl_exec($ch);
curl_close($ch);
return $result;
It keeps returning a 500 internal server error which is the same as if you go direct to the url so it's like the POST data isn't being sent. But I haven't check the content length and it seems to be..
Any Ideas?

try just this
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_string); // NOTE used $xml_string to indicate its just a text string of XML format
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_NOPROGRESS, 0);
$result = curl_exec($ch);
curl_close($ch);

Curl redirect not working?

My CURL redirect is not working i am redirected to same page but the same page is empty when it is rendered after i submit it. Here is my code.
$ch = curl_init("http://localhost/soft/entercode.php");
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'variable1=abc&variable2=123');
$result = curl_exec($ch);
curl_close($ch);

look into the configurations cause this error is sometime caused by installed CURL check that if the installation files have all the required files for win 32 version of CURL.

Try adding and changing:
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
Hope it works for you

$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,"http://localhost/soft/entercode.php");
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,2);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'variable1=abc&variable2=123');
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true);
curl_setopt($ch,CURLOPT_MAXREDIRS,1);
$buffer = curl_exec($ch);
curl_close($ch);
Check this it will work ..

curl fetching content of redirected webpage

I try to login in a site which has a combined login.
The redirect to this site works fine and the redirect back as well ... but only if I stop the PHP programm with die(). Unfortunately it is not stored in $return, which I would need to proceed.
Any ideas, what I am doing wrong? Much appreciated!
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_UNRESTRICTED_AUTH, TRUE);
curl_setopt($ch, CURLOPT_POSTREDIR, TRUE);
curl_setopt($ch, CURLOPT_URL, URI_LOGIN);
$content = curl_exec($ch);
// PREPARING THE LOGIN
$referer = URI_LOGIN . '?ReturnUrl=' . urlencode('/returnUrl/');
curl_setopt($ch, CURLOPT_URL, $referer);
curl_setopt($ch, CURLOPT_REFERER, $referer);
curl_setopt($ch, CURLOPT_COOKIEJAR, COOKIE);
$post = ...;
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post) );
curl_setopt($ch, CURLOPT_USERAGENT, '...');
curl_setopt($ch, CURLINFO_HEADER_OUT, TRUE);
$content = curl_exec($ch);
// LOGIN
curl_setopt($ch, CURLOPT_URL, COMBINED_LOGIN);
$post = ...;
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post) );
$return = curl_exec($ch);
// ...
?>

There was a problem with javascript. It stucked on an 'in-between'-page and I had to make another curl request to get to the right page.
Now it is working fine!
