Can I write a PHP file (index.php) that when someone point it browser to
http://www.domain.org/some?params=a&b=1
it returns the content of
http://www.OTHERdomain.org/some?params=a&b=1
Should I use culr?
From http://www.php.net/manual/en/curl.examples-basic.php#88055, this is the code you need:
<?php
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "example.com");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
?>
You could create a page called proxy.php or something like that that takes a URL as the parameter. Then, you can replace domain.org with otherdomain.org in the URL. Then use CURL to get the contents and return it.

I am using curl request to hit the has-offers conversion url from my sevrver with the help of curl but it is not working.But when I call the same URL using a browser, it works.Is they can block CURL requests?.I am not getting why, is there any port blocking issue.
Below is php code to call url using curl request.
<?php
function curl_get_contents($url)
{
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$url="http://paravey.go2cloud.org/aff_l?offer_id=12&aff_id=1000";
$contents = curl_get_contents($url);
echo $contents;
?>
Please help me thanks in Advance
The url you are curling is a pixel tracking url:
http://paravey.go2cloud.org/aff_l?offer_id=12&aff_id=1000
The aff_l endpoint looks for a cookie with session information (hence why it works in the browser).
If you want to create conversions with server side code, you will need to store the session identifier (the transaction_id) in your system and use the aff_lsr endpoint to send that data to HasOffers to trigger a conversion.
The url for this would look like this:
http://paravey.go2cloud.org/aff_lsr?transaction_id= VALUE
Where Value is the session identifier you have stored.
I would ask the HasOffers support team if you have more issues with this.
So I'm trying to have users verify that they own the domain. So I generated a file and have them upload it to their site. So I then have to verify it, so what I do is
file_get_contents($url.'/'.$token.'.html');
All this returns is
bool(false)
Here's more of the code
$url = $_POST['url'];
//Get site info
$gin = $con->prepare("SELECT * FROM verify WHERE url = :url");
$gin->bindValue(':url', $url);
$gin->execute();
//Get token
$t = $gin->fetch(PDO::FETCH_ASSOC);
$token = $t['token'];
$url = $t['url'];
//Get content
var_dump(file_get_contents($url.'/'.$token.'.html'));
I have 3 columns in the table token, which is the string in the file. url which is the url obviously, its in example.com format. And a verified column which is either 1 or 0. Any ideas?
Based on my experience with fetching third-party content from more than 1 million domain names, I would not recommend you to use file_get_contents() because this PHP function cannot handle page redirects, site that requires a valid user-agent etc. The issue you are experiencing might be specific to a certain domain names only. A better approach to your problem is to use curl.
function download_content($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_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_USERAGENT, "Firefox 32.0");
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
Usage:
$returned_content = download_content('http://stackoverflow.com');
Try to add http:// before $url and put a valid url. It will work
var_dump(file_get_contents('http://'.$url.'/'.$token.'.html')); // With a valid URL
If you enable error_reporting(E_ALL), then you will probably see that the use of HTTP URLs are disallowed due to an ini setting.
Warning: you are possibly opening a hole by allowing arbitrary prefixes in file_get_contents. Try to use parse_url to validate that you actually have a HTTP URL. Then you should probably consider using cURL and disable external redirects (otherwise one could pass a URL such as http://bit.ly/something# and still pass your tests).
Hi I am new to php and want to know some alternate function for the header('location:mysit.php');
I am in a scenario that I am sending the request like this:
header('Location: http://localhost/(some external site).php'&?var='test')
something like this but what I wanna do is that I want to send values of variables to the external site but I actually dont want that page to pop out.
I mean variables should be sent to some external site/page but on screen I want to be redirected to my login page. But seemingly I dont know any alternative please guide me. Thx.
You are searching for PHP cUrl:
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
Set the location header to the place you actually want to redirect the browser to and use something like cURL to make an HTTP request to the remote site.
The way you usually would do that is by sending those parameters by cURL, parse the return values and use them however you need.
By using cURL you can pass POST and GET variables to any URL.
Like so:
$ch = curl_init('http://example.org/?aVariable=theValue');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
curl_close($ch);
Now, in $result you have the response from the URL passed to curl_init().
If you need to post data, the code needs a little more:
$ch = curl_init('http://example.org/page_to_post_to.php');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'variable1=value1&variable2=value2');
$result = curl_exec($ch);
curl_close($ch);
Again, the result from your POST reqeust is saved to $result.
You could connect to another URL in the background in numerous ways. There's cURL ( http://php.net/curl - already mentioned here in previous comments ), there's fopen ( http://php.net/manual/en/function.fopen.php ), there's fsockopen ( http://php.net/manual/en/function.fsockopen.php - little more advanced )
I have a function make_curl_request to make curl request.
/**
* General Function to make curl request */
function make_curl_request($url, $data)
{
ob_start();
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_exec($ch);
curl_close($ch);
$strCurlResponse = ob_get_contents();
ob_end_clean();
return $strCurlResponse;
}
I am calling it like:
$strGatewayResponse = make_curl_request( REQUEST_URL, compact('strMobileNo', 'strKeywords', 'strApiKey') );
I tried the things but can't get my code working fine. Currently its just return string("") as the output. Where am i going wrong?
My target is to simple post few data to next page located on other domain and get its xml response and parse it and display it. Is there any other simple and good solution?
The problem is that you've got RETURNTRANSFER set to TRUE, which means curl returns its output instead of directly outputting it. However, you're not capturing that output in a variable, so it's dropping on the floor.
You've got two options
a) remove the ob_*() functions to remove the PHP buffering and then do
$data = curl_exec($ch)
if ($data === FALSE) {
die("Curl failed: " . curL_error($ch));
}
after which $data contains the contents of the URL you've fetched.
b) remove the RETURNTRANSFER option, and let curl do its normal "output to client directly" thing, which then gets captured by the PHP output buffering.
Try by adding a row:
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
FALSE to stop cURL from verifying the peer's certificate. Alternate certificates to verify against can be specified with the CURLOPT_CAINFO option or a certificate directory can be specified with the CURLOPT_CAPATH option.
it's not ok to send a curl POST without a header.

This question is simple. What function would I use in a PHP script to load data from a URL into a string?
CURL is usually a good solution: http://www.php.net/curl
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// grab URL and pass it to the browser
$html = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
I think you are looking for
$url_data = file_get_contents("http://example.com/examplefile.txt");
With file wrappers you can use file_get_contents to access http resources (pretty much just GET requests, no POST). For more complicated http requests you can use the curl wrappers if you have them installed. Check php.net for more info.
