PHP - File_get_contents And Curl Not Working For Some Url

Hello there,

The error i have is that my server can't find itself and it gives me this nice error. Quote

php_network_getaddresses: getaddrinfo failed: Temporary failure in name resolution in...


You maybe thinking why don't i just include the file or use its relative location (./file.php) but the answer is simple. It doesn't fit in with my framework and its too hard to expand.

How else can I execute a file on the same domain using PHP?

Thank-you
Paul

I have an integration with a third party that utilizes a SOAP API.  On my current server AND my local environment, this works fine.

I recently deployed a new server and it seems that cURL isn't doing anything.  *The code is identical on all three installations.

The "error" that I am seeing is no response at all (no response and no error, however, I can see that it is a "Resource").

After much trial and error, I tried creating a simple cURL example to test try to rule out other issues as the code itself is quite complex.  My simple example, that also fails, is as follows:

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, "google.com");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$output = curl_exec($ch);
$err = curl_error($ch);

print_r($err);
echo $output;
curl_close($ch);

  This does the same thing.  On local, I get a "301 Moved" notice, on the new server, it is just a white screen.

I have confirmed that php has curl installed in via command line (php -m) and using phpinfo(); in my code.  It is definitely enabled.

What would cause cURL to not have a response AND not have an error?  My thought is a server setting, but I can't seem to find what might be causing this.

Thanks

I have never used cURL before but I need to use it for developing a facebook application. What I am trying to do is create a status update scheduler. There are two tables in my database. One table has generic updates for each day of the week an the other had special events. My script checks the day, checks to see if there is a special event in the future on that day, and if there is reminds guests of the upcoming event. If there is no event it posts the generic status.

Code: [Select]
<?php 
include('config.php');

$result2 = mysql_query("select facebook_id,facebook_access_token from admin where username='users'");
$row = mysql_fetch_array($result2);
$facebook_id = $row['facebook_id'];
$facebook_access_token = $row['facebook_access_token'];

$day = date('N');

$result2 = mysql_query("select * from events where date > CURDATE() order by date ASC")
or die(mysql_error());

$num_rows = mysql_num_rows($result2);

if($num_rows == 0) {
$result2 = mysql_query("select * FROM alerts WHERE id='$day'")
or die(mysql_error());
$row1  = mysql_fetch_array($result2);
echo 'There are no events just alerts';
} else {
while($row = mysql_fetch_array($result2)){
if(date('N',strtotime($row[date])) == $day) {

$id = $row['id'];

$result1 = mysql_query("SELECT * FROM events WHERE id = $id")
or die(mysql_error());

$row1  = mysql_fetch_array($result1);

} else {
$result1 = mysql_query("SELECT * FROM alerts WHERE id = $day")
or die(mysql_error());
$row1  = mysql_fetch_array($result1);

}
}
}

$params = array('access_token' => $facebook_access_token, 
'message' => $row1[alert_message],
'name'=> $row1[alert_name],
'caption' => $row1[alert_caption],
'link' => $row1[alert_link],
'description' => $row1[alert_description],
'picture' => $row1[alert_picture]
);

$url = "https://graph.facebook.com/$facebook_id/feed";
$ch = curl_init();
curl_setopt_array($ch, array(
CURLOPT_URL => $url,
CURLOPT_POSTFIELDS => $params,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_SSL_VERIFYPEER => false,
CURLOPT_VERBOSE => true
 ));

$result = curl_exec($ch);

?>
The problem seems to be occurring when the While loop is accessed. I have used 'echo' to follow the variables through the script and it all seems to be working. However if I try and execute the cURL and the While Loop has run then it does not seem to work. I know the cURL part works becuase if the variables cause the first IF statement default to ELSE then it runs fine.

Any help would be GREATLY appreciated.

Users make entries into a form on my site which are then sent to a remote server which generates a variable length page of results for the users perusal.  I want the results to be displayed on my site but I discover that iframe height is a problem so I am trying PHP in a separate file to avoid an iframe.  Then maybe I can cache the result pages and display them without any height difficulties and not having to fiddle with javascript.

The first PHP code I try is prevented from working and I discover that the apparent cause is the issue of fopen and fsockopen etc. being set to off by the host that I use because of security concerns:

$url="http://remote_server.cgi";
foreach($_POST as $key => $value)
{$url .="$key=" . urlencode($value) . "&";}
$array = file($url);]

The host has cURL so I try that but the form entries are not being accepted as they are with a direct post from the form:

$URL="http://remote_server.cgi";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $URL); 
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $_POST);
curl_exec ($ch);    
curl_close ($ch);

In case useragent is a problem at the remote server, I added:

curl_setopt($ch,CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');

I know all entries are received by the separate file by using:

print_r($_POST);

But the remote server still says "Error in form found. You are not authorized etc. etc... "

Apparently the post data is not being sent like the form sends it.

Any suggestions?

Ive tried everything and cannot get this POST to work, page comes up blank. The output of curlgetinfo() shows:

I am trying to create a remote login to one website using mine. The users will need to enter their username and password on my site, and if they are registered to my website, their login credentials will be sent to another website and a page will be retrieved. I am stuck at sending the users' data to the original site. The original site's viewsource is this..

<form method=post>
<input type="hidden" name="action" value="logon">
<table border=0>
<tr>
<td>Username:</td>
<td><input name="username" type="text" size=30></td>
</tr>
<tr>
<td>Password:</td>
<td><input name="password" type="password" size=30></td>
</tr>
<td></td>
<td align="left"><input type=submit value="Sign In"></td>
</tr>
<tr>
<td align="center" colspan=2><font size=-1>Don't have an Account ?</font> <a href="?action=newuser"><font size=-1 color="#0000EE">Sign UP Now !</font></a></td>
</tr>
</table>

I have tried this code, but not works.

<?php
$username="username"; 
$password="password"; 
$url="http://www.example.com/index.php"; 

$postdata = "username=".$username."&password=".$password;

$ch = curl_init(); 
curl_setopt ($ch, CURLOPT_URL, $url); 
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt ($ch, CURLOPT_REFERER, $url); 
curl_setopt ($ch, CURLOPT_POSTFIELDS, $postdata); 
curl_setopt ($ch, CURLOPT_POST, 1); 
$result = curl_exec ($ch); 
header('Location: track.html'); 
//echo $result;  
curl_close($ch);
?>

Any help would be appreciated, Thanks in advance.

I have a CURL code that fetches some XML content from a remote server. I get the expected output on my localhost (XAMPP on windows). But from the live site(hosted on Linux), I get the CURL error:'couldn't connect to host'.

function DownloadUrl($Url, $p){
 
// is curl installed?
if (!function_exists('curl_init')){ 
die('CURL is not installed!');
}

       // create curl resource
        $ch = curl_init();

        // set url
        curl_setopt($ch, CURLOPT_URL, $Url);

   curl_setopt ($ch, CURLOPT_POSTFIELDS, $p);
   curl_setopt ($ch, CURLOPT_POST, 1);
        //return the transfer as a string
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

        // $output contains the output string
        $output = curl_exec($ch);
        
   if($output === false)
   echo 'Curl error: ' . curl_error($ch);
   else
     print $output;
        // close curl resource to free up system resources
        curl_close($ch);

Hello PHP Freaks!

I have the following PHP Curl code which is supposed to fetch the twitter timeline feed for a specific username and parse and display it on a page, but for some reason Curl is unable to fetch data from twitter:

Code: [Select]
<?php
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;
}

$json = get_data("https://api.twitter.com/1/statuses/user_timeline.json?include_entities=true&include_rts=true&screen_name=digioz&count=2");

if ($json != false)
{
    $obj = json_decode($json);
        
    foreach($obj as $var => $value)
    {
        echo "Message number: $var <br/>";    
        echo "Name: " . $obj[$var]->user->name;
        echo "Handle: " . $obj[$var]->user->screen_name . "<br/>";        
        echo "Message: " . $obj[$var]->text;        
        echo "Created" . $obj[$var]->created_at . "<br/>";                    
        echo "URL" . $obj[$var]->user->url . "<br/>";
        echo "Location" . $obj[$var]->user->location . "<br/>";       
        echo "<br/>";
    }
}
else
{
    echo "Could not fetch Twitter Data";
}
?>

Anyone have any idea why the data is not being fetched? If I copy and paste the URL into my browser window it returns results just fine, so I know the problem is not with the URL.

Thanks,
Pete

Hi All,

My goal is to process all redirects serverside and simply return the user to the 'final' URL.

Here's my function to get the final URL:
PHP Code:
function get_final_url($url){ 
    global $final_host; 
        $redirects = get_all_redirects($url); 
        if (count($redirects)>0){ 
          $final_url = array_pop($redirects); 
          if(substr($final_url,0,7) != 'http://' && !empty($final_host)) 
            { $final_url = 'http://'.$final_host.$final_url; } 
                return $final_url; 
        } else { 
                return $url; 
        } 

Here's the cURL execution:

$ch2 = curl_init();      
                        curl_setopt($ch2,CURLOPT_URL,$url); 
                        curl_setopt($ch2, CURLOPT_FOLLOWLOCATION, true); 
                        curl_setopt($ch2,CURLOPT_POST,''); 
                        curl_setopt($ch2,CURLOPT_POSTFIELDS,''); 
                        curl_exec($ch2); 
                        curl_close($ch2); 

For some reason, this works no problem, posts any data over to the URLs serverside, redirects serverside, and passes the client to the final URL, with none of the redirection displayed via HTTPWatch or any similar debug utility. Sometimes, however, it does show phases of redirection.

Any insight into what I might be doing incorrectly?

Thanks SO much in advance.

good day dear community,

i am workin on a Curl loop to fetch multiple pages:

i have some examples - and a question:

Example: If we want to get information from 3 sites with CURL we can do it like so:


$list[1] = "http://www.example1.com";
$list[2] = "ftp://example.com";
$list[3] = "http://www.example2.com";


After creating the list of links we should initialize the cURL multi handle and adding the cURL handles.


$curlHandle = curl_multi_init();
for ($i = 1;$i <= 3; $i++)
 $curl[$i] = addHandle($curlHandle,$list[$i]);


Now we should execute the cURL multi handle retrive the
content from the sub handles that we added to the cURL multi handle.

ExecHandle($curlHandle);
for ($i = 1;$i <= 3; $i++)
{
 $text[$i] =  curl_multi_getcontent ($curl[$i]);
 echo $text[$i];
}

In the end we should release the handles from the cURL multi handle by calling curl_multi_remove_handle and close the cURL multi handle!

If we want to another Fetch of sites with cURL-Multi - since this is the most pretty way to do it!
Well I am not sure bout the string concatenation. How to do it - Note I want to fetch several hundred pages:
see the some details for this target-server sites - /(I have to create a loop over several hundred sites).

    * siteone.example/?show_subsite=9009
    * siteone.example/?show_subsite=9742
    * siteone.example/?show_subsite=9871

.... and so on and so forth Question: How to appy this loop into the array of the curl-multi?

I look forward to your ideas.

<?php


$1 = file_get_contents("");
$2 = json_decode($1);
$3 = $2->result;

var_dump($myData1);
 foreach($3 as $key => $item): 
     echo $item->Users->UserObject->UserName; 
endforeach; 

?>

{
  "result": [
    {
      "ID": 1,
     
      "Users": [
        {

        }
      ],
    
      "IsActive": true
    }
  ],

}

I get this error Notice: Trying to get property 'UserObject' of non-object in C:\xampp\htdocs\dashboard-master\chart.php on line 10

Notice: Trying to get property 'UserName' of non-object in C:\xampp\htdocs\dashboard-master\chart.php on line 10

This works great but I only need part of the page for example the right column...can I do this with a class or some how.  What this is is pulling information from another site.

Code: [Select]

<?php $g = file_get_contents("http://www.site.com/index.php");
echo ($g);
?>

Okay, so I'm trying to make a service to detect proxies. Heres what I need to know..
This is how I have it set up:
1. I have a file on mysite.com/check.php
2. My clients create a page to load my check.php file on THEIR website using file_get_contents(); Like: file_get_contents("http://mysite.com/check.php?ip=$_SERVER['REMOTE_ADDR']");
3. My system checks for a proxy using HTTP vars, how would I get them?? Like.. if I echo $_SERVER['REMOTE_ADDR']; out on the page on MY end, it will echo the servers IP to check is using step #2 with file_get_contents();

Can anyone please help me? I am willing to pay a little, if needed :/
Thanks in advance!
