Examples
Example #1 curl_getinfo() example
<?php
// Create a curl handle
$ch = curl_init('http://www.yahoo.com/');
// Execute
curl_exec($ch);
// Check if any error occurred
if(!curl_errno($ch))
{
$info = curl_getinfo($ch);
echo 'Took ' . $info['total_time'] . ' seconds to send a request to ' . $info['url'];
}
// Close handle
curl_close($ch);
?>
Notes
Note:
Information gathered by this function is kept if the handle is re-used. This means that unless a statistic is overridden internally by this function, the previous info is returned.

if (!$ch) {
die("Couldn't initialize a cURL handle");
}
// set some cURL options
$ret = curl_setopt($ch, CURLOPT_URL, "http://mail.yahoo.com");
$ret = curl_setopt($ch, CURLOPT_HEADER, 1);
$ret = curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$ret = curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
$ret = curl_setopt($ch, CURLOPT_TIMEOUT, 30);
// execute
$ret = curl_exec($ch);
if (empty($ret)) {

// load the HTTP codes
$http_codes = parse_ini_file("path/to/the/ini/file/I/pasted/above");
// echo results

echo $info['http_code'] . " " . $http_codes[$info['http_code']];

}

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.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.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."

curl_getinfo($ch) will also return 'redirect_url' if there is one (even if CURLOPT_FOLLOWLOCATION set to false).I don't know why it's not in the doc..
Here you have a function that I use to get the content of a URL using cURL. This uses curl_getinfo to know if it is a regular URL or maybe a redirection.
I hope it would be useful for you:
function getUrlContent($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;
}

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.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 !!!
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);
A note about $curl_info['header_size'] (in response to the example above).
Note that the total includes the size of any received headers suppressed by CURLOPT_SUPPRESS_CONNECT_HEADERS (see: https://curl.se/libcurl/c/CURLINFO_HEADER_SIZE.html) so if you are using a proxy which adds additional headers along with this option, $curl_info['header_size'] will give you the wrong string index based on the headers available in PHP. i.e., it will eat in to the start of the response instead of being the index of the beginning of the response.
You can still get the SSL verification result using CURLINFO_SSL_VERIFYRESULT when setting CURLOPT_SSL_VERIFYPEER to FALSE.
