Параметри

ch

A cURL handle returned by curl_init().

opt

This may be one of the following constants:

CURLINFO_STARTTRANSFER_TIME - Time in seconds until the first byte is about to be transferred
CURLINFO_REDIRECT_COUNT - Number of redirects, with the CURLOPT_FOLLOWLOCATION option enabled
CURLINFO_REDIRECT_TIME - Time in seconds of all redirection steps before final transaction was started, with the CURLOPT_FOLLOWLOCATION option enabled
CURLINFO_REDIRECT_URL - With the CURLOPT_FOLLOWLOCATION option disabled: redirect URL found in the last transaction, that should be requested manually next. With the CURLOPT_FOLLOWLOCATION option enabled: this is empty. The redirect URL in this case is available in CURLINFO_EFFECTIVE_URL
CURLINFO_PRIMARY_IP - IP address of the most recent connection

CURLINFO_HEADER_OUT - The request string sent. For this to work, add the CURLINFO_HEADER_OUT option to the handle by calling curl_setopt()
CURLINFO_REQUEST_SIZE - Total size of issued requests, currently only for HTTP requests
CURLINFO_SSL_VERIFYRESULT - Result of SSL certification verification requested by setting CURLOPT_SSL_VERIFYPEER
CURLINFO_CONTENT_LENGTH_DOWNLOAD - content-length of download, read from Content-Length: field
CURLINFO_CONTENT_LENGTH_UPLOAD - Specified size of upload
CURLINFO_CONTENT_TYPE - Content-Type: of the requested document, NULL indicates server did not send valid Content-Type: header
CURLINFO_PRIVATE - Private data associated with this cURL handle, previously set with the CURLOPT_PRIVATE option of curl_setopt()

Значення, що повертаються

If opt is given, returns its value. Otherwise, returns an associative array with the following elements (which correspond to opt), or FALSE on failure:

"url"
"content_type"
"http_code"
"header_size"
"request_size"
"filetime"
"ssl_verify_result"
"redirect_count"
"total_time"
"namelookup_time"
"connect_time"
"pretransfer_time"
"size_upload"
"size_download"
"speed_download"
"speed_upload"
"download_content_length"
"upload_content_length"
"starttransfer_time"
"redirect_time"
"certinfo"
"primary_ip"
"primary_port"
"local_ip"
"local_port"
"redirect_url"
"request_header" (This is only set if the CURLINFO_HEADER_OUT is set by a previous call to curl_setopt())

Note that private data is not included in the associative array and must be retrieved individually with the CURLINFO_PRIVATE option.

Here you have a function that I use to get the content of a URL using cURL. This uses curl_getinfo to know if it is a regular URL or maybe a redirection.

I hope it would be useful for you:

function getUrlContent($url){
 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, $url);
 curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)');
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
 curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
 curl_setopt($ch, CURLOPT_TIMEOUT, 5);
 $data = curl_exec($ch);
 $httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
 curl_close($ch);
 return ($httpcode>=200 && $httpcode<300) ? $data : false;
}

CURLINFO_HTTP_CODE does not return a string, as the docs say, but rather an integer.

<?php
    $c = curl_init('http://www.example.com/');
    if(curl_getinfo($c, CURLINFO_HTTP_CODE) === '200') echo "CURLINFO_HTTP_CODE returns a string.";
    if(curl_getinfo($c, CURLINFO_HTTP_CODE) === 200) echo "CURLINFO_HTTP_CODE returns an integer.";
    curl_close($c);
?>

returns

"CURLINFO_HTTP_CODE returns an integer."

There is a constant missing from that list.  CURLINFO_REDIRECT_COUNT will give you the number of redirects it went through if CURLOPT_FOLLOWLOCATION was set.

Just a quick note: if you want to use curl_getinfo() with option CURLINFO_HEADER_OUT in order to debug your cURL request, you must add curl_setopt($handle, CURLINFO_HEADER_OUT, true); first while specifying the options.

Note, header_size include "\r\n\r\n". So if you use CURLOPT_FOLLOWLOCATION>0, CURLOPT_HEADER=true, CURLOPT_RETURNTRANSFER=true right way splite header/body:

$response = curl_exec($ch);
$curl_info = curl_getinfo($ch);
curl_close($ch);
$header_size = $curl_info['header_size'];
$header = substr($response, 0, $header_size);
$body = substr($response, $header_size);

curl_getinfo($ch) will also return 'redirect_url' if there is one (even if CURLOPT_FOLLOWLOCATION set to false).
I don't know why it's not in the doc..

If you call curl_reset() on a handle that has already been passed to curl_exec(), and then perform a curl_getinfo() on the same handle, you may expect that you get the same result as if you called curl_getinfo() immediately after curl_init(). This is not the case, however. cURL will return the data from the previous execution. If you want to completely reset you actually need to unset the cURL handle and recreate a new one.

The main doc neglects to mention that when the CURLINFO_HEADER_OUT option is set the array returned by this function will included a new property, request_header, that is a string of the headers sent in the request.

If you use curl option CURLOPT_NOBODY = true to test if distant url is available, any sites can send you an http code 400 like Cdiscount Wsdl : 

$ch = @curl_init($wsdl);

if($ch === false)
    return false;
        
@curl_setopt($ch, CURLOPT_HEADER         ,true);    // we want headers
@curl_setopt($ch, CURLOPT_NOBODY         ,true);    // dont need body
@curl_setopt($ch, CURLOPT_RETURNTRANSFER ,true);    // catch output (do NOT print!)

@curl_exec($ch);

if(@curl_errno($ch)){   // should be 0
    @curl_close($ch);
    return false;
}

$code = @curl_getinfo($ch, CURLINFO_HTTP_CODE); 

Modifying CURLOPT_NOBODY to false, http code sent is 200 otherwise http code is 400 !!!

Keep in mind that for CURLOPT_RETURNTRANSFER it has to be set with curl_setopt() before execution:

This doesn't work:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));
?>

This works:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_exec($ch);
var_dump(curl_getinfo($ch,CURLINFO_HEADER_OUT));
?>

Example 1 should use "if(curl_errno($ch))" not "if(!curl_errno($ch))"
