curl does not seem to work with SSL TLS (FTPES)
It will throw the following error:
(1) Protocol ftpes not supported or disabled in libcurl
frank at interactinet dot com (2011-03-11 21:29:24)
I wrote the following to see if a submitted URL has a valid http response code and also if it responds quickly.
Use the code like this:
<?php
$is_ok = http_response($url); // returns true only if http response code < 400
?>
The second argument is optional, and it allows you to check for a specific response code
<?php
http_response($url,'400'); // returns true if http status is 400
?>
The third allows you to specify how long you are willing to wait for a response.
<?php
http_response($url,'200',3); // returns true if the response takes less than 3 seconds and the response code is 200
?>
<?php
function http_response($url, $status = null, $wait = 3)
{
$time = microtime(true);
$expire = $time + $wait;
// we fork the process so we don't have to wait for a timeout
$pid = pcntl_fork();
if ($pid == -1) {
die('could not fork');
} else if ($pid) {
// we are the parent
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_NOBODY, TRUE); // remove body
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$head = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);
if(!$head)
{
return FALSE;
}
if($status === null)
{
if($httpCode < 400)
{
return TRUE;
}
else
{
return FALSE;
}
}
elseif($status == $httpCode)
{
return TRUE;
}
return FALSE;
pcntl_wait($status); //Protect against Zombie children
} else {
// we are the child
while(microtime(true) < $expire)
{
sleep(0.5);
}
return FALSE;
}
}
?>
Hope this example helps. It is not 100% tested, so any feedback [sent directly to me by email] is appreciated.

This anomali only happen on windows.
Server indicates that some variables built by http_build_query() is missing.
<?php
//...
//...
//...
$ping_url = $this->sx_url.'ping.php?'.http_build_query($options);
$message = $this->_post_curl($ping_url);
?>
After debugging i found that $ping_url contain url like :
http://example.com/ping.php?app=1&key=mail&ttd=df52861e
But myserver give "No ttd GET variable" response
This problem fixed by adding optional parameter to make sure that http_build_query() use only '&' as arg separator rather than '&'
<?php
//...
//...
//...
$ping_url = $this->sx_url.'ping.php?'.http_build_query($options,'','&');
$message = $this->_post_curl($ping_url);
?>

CURL failed with PHP5.3 and Apache2.2.X on my Windows 7 machine.
It turns out that it's not enough to copy the two dll's mentioned (libeay32 and sslea32) from the php folder into your system32 folder. You HAVE TO UNBLOCK THESE TWO FILES.
Right click the file, select unblock, for each one. Then restart Apache.
Another very handy security feature added into Windows.

I needed to use cURL in a php script to download data using not only SSL for the server authentication but also for client authentication.
On a default install of Fedora, setting up the proper cURL parameters, I would get an error:
$ php curl.php
Peer certificate cannot be authenticated with known CA certificates
The data on http://curl.haxx.se/docs/sslcerts.html was most useful. Indeed, toward to bottom it tells you to add a missing link inside /etc/pki/nssdb to use the ca-bundle.crt file. You do it so:
# cd /etc/pki/nssdb
# ln -s /usr/lib64/libnssckbi.so libnssckbi.so
Now you can do client authentication, provided you have your certificate handy with:
<?php
$data = "<soap:Envelope>[...]</soap:Envelope>";
$tuCurl = curl_init();
curl_setopt($tuCurl, CURLOPT_URL, "https://example.com/path/for/soap/url/");
curl_setopt($tuCurl, CURLOPT_PORT , 443);
curl_setopt($tuCurl, CURLOPT_VERBOSE, 0);
curl_setopt($tuCurl, CURLOPT_HEADER, 0);
curl_setopt($tuCurl, CURLOPT_SSLVERSION, 3);
curl_setopt($tuCurl, CURLOPT_SSLCERT, getcwd() . "/client.pem");
curl_setopt($tuCurl, CURLOPT_SSLKEY, getcwd() . "/keyout.pem");
curl_setopt($tuCurl, CURLOPT_CAINFO, getcwd() . "/ca.pem");
curl_setopt($tuCurl, CURLOPT_POST, 1);
curl_setopt($tuCurl, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($tuCurl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($tuCurl, CURLOPT_POSTFIELDS, $data);
curl_setopt($tuCurl, CURLOPT_HTTPHEADER, array("Content-Type: text/xml","SOAPAction: \"/soap/action/query\"", "Content-length: ".strlen($data)));
$tuData = curl_exec($tuCurl);
if(!curl_errno($tuCurl)){
$info = curl_getinfo($tuCurl);
echo 'Took ' . $info['total_time'] . ' seconds to send a request to ' . $info['url'];
} else {
echo 'Curl error: ' . curl_error($tuCurl);
}
curl_close($tuCurl);
echo $tuData;

A solution that addresses repeat calls to the same set of urls using the same connection simulating frequent ajax calls in separate browser tabs.
In a unique situation you may need to set a cookie then use that cookie for multiple separate persistent connections using the same session cookie. The problem is the session cookie may change while your doing your persistent calls. If you set every curl handle to update a shared cookiejar on close you may overwrite the new found session value with the old session value depending on the closing order of your handles. Also, because the cookiejar is only written to on a curl_close, you may be using dissimilar or old session info in some of your 'faked browser tabs'.
To solve this problem I created a unique handle that opens and closes specifically to set a cookie file using CURLOPT_COOKIEJAR. Then I just use the read-only CURLOPT_COOKIEFILE on the multiple separate persistent handles.
This solves the problem of shared cookies fighting to write their values and keep persistent calls using the most up to date cookie information.
Note: In my case the multiple calls were in a while loop and I was using php in shell. The session cookie value plus browser type limited the number of connections available and i wanted to use the max connections per session.

When using curl with cookies, Relative path doesn't seem to work.
Use absolute path for setting the variables CURLOPT_COOKIEFILE & CURLOPT_COOKIEJAR.
To make life easier use the realpath("file.txt") function to get the absolute path.
Chris Pollett (2010-01-18 18:56:50)
This is something obscure I noticed... If you try to use something like:
<?php
curl_setopt($agent, CURLOPT_POST, true);
curl_setopt($agent, CURLOPT_POSTFIELDS, $post_data);
?>
so that you POST something to a URL. Then if you screwed up your URL slightly like:
http://www.example.com
rather than
http://www.example.com/ (note the slash)
hence, causing a redirect, then your posted data won't be sent once the redirect occurs.

A simple whois/domain availability check using cURL:
<?php
function domain_check($domain) {
$data = 'http://'.$domain;
// Create a curl handle to a non-existing location
$ch = curl_init($data);
// Execute
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
// Check if any error occured
if(curl_errno($ch))
{
return '<span style="color:#22c922">The domain is available!</span>';
} else {
return '<span style="color:#c92222">The domain is not available</span>';
}
// Close handle
curl_close($ch);
}
// Usage:
if(isset($_POST['domain'])) {
echo domain_check($_POST['domain'].$_POST['tld']);
}
?>
<form method="POST" action="">
http:// <input type="text" name="domain">
<select name="tld">
<option value=".com">.com</option>
<option value=".net">.net</option>
<option value=".biz">.biz</option>
</option>
<input type="submit" value="Check">
</form>

[EDIT BY danbrown AT php DOT net: Contains a bugfix supplied by "roetsch.beni at googlemail (dot) com" on 02-AUG-09, with the following note: "Fixes the bugfix: 417 bug at lighthttp server."]
admin at jeremyzaretski dot com (2009-03-18 08:14:11)
I wanted to create a script that acted as a bridge between an external server and an internal server, wherein the internal server was not connected to the internet, but had information required by the users connecting to the external server. I hatched the idea to use curl to connect from the external server to the internal server (using request variables to send queries) and return everything (data and headers) returned by the file server.
After being driven mad by segmentation faults and crashes because the curl_exec didn't like me having the CURLOPT_HEADERFUNCTION's function directly dumping the header:
<?php
function Duplicate_Header($curl, $header)
{
header($header);
return strlen($header);
}
?>
... I tried (on a whim) duplicating and trimming the header and passing the duplicate to the header function...
<?php
function Duplicate_Header($curl, $header)
{
$duplicate = trim($header);
header($duplicate);
return strlen($header);
}
?>
Which worked just fine. I don't know if this is just some quirk of PHP4 or my lack of understanding of how the curl and header function works.

In order to use curl with secure sites you will need a ca-bundle.crt file; here's a PHP script I've written which creates a fresh ca-bundle:
http://www.gknw.net/php/phpscripts/mk-ca-bundle.php
I've also written scripts in other languages, f.e. the Perl one which ships now with curl distributions:
http://curl.haxx.se/lxr/source/lib/mk-ca-bundle.pl
and also a Win32 WSH script if you prefer that:
http://www.gknw.net/vb/scripts/mk-ca-bundle.vbs
