Description

curl_getinfo ( CurlHandle $handle [, int|null $option = NULL ] ) : mixed

Gets information about the last transfer.


Parameters

handle
A cURL handle returned by curl_init().
option
This may be one of the following constants:
  • CURLINFO_EFFECTIVE_URL - Last effective URL
  • CURLINFO_HTTP_CODE - The last response code. As of PHP 5.5.0 and cURL 7.10.8, this is a legacy alias of CURLINFO_RESPONSE_CODE
  • CURLINFO_FILETIME - Remote time of the retrieved document, with the CURLOPT_FILETIME enabled; if -1 is returned the time of the document is unknown
  • CURLINFO_TOTAL_TIME - Total transaction time in seconds for last transfer
  • CURLINFO_NAMELOOKUP_TIME - Time in seconds until name resolving was complete
  • CURLINFO_CONNECT_TIME - Time in seconds it took to establish the connection
  • CURLINFO_PRETRANSFER_TIME - Time in seconds from start until just before file transfer begins
  • 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_PRIMARY_PORT - Destination port of the most recent connection
  • CURLINFO_LOCAL_IP - Local (source) IP address of the most recent connection

  • CURLINFO_SPEED_DOWNLOAD - Average download speed
  • CURLINFO_SPEED_UPLOAD - Average upload speed
  • CURLINFO_HEADER_SIZE - Total size of all headers received
  • 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()
  • CURLINFO_RESPONSE_CODE - The last response code
  • CURLINFO_HTTP_CONNECTCODE - The CONNECT response code
  • CURLINFO_HTTPAUTH_AVAIL - Bitmask indicating the authentication method(s) available according to the previous response
  • CURLINFO_PROXYAUTH_AVAIL - Bitmask indicating the proxy authentication method(s) available according to the previous response
  • CURLINFO_OS_ERRNO - Errno from a connect failure. The number is OS and system specific.
  • CURLINFO_NUM_CONNECTS - Number of connections curl had to create to achieve the previous transfer
  • CURLINFO_SSL_ENGINES - OpenSSL crypto-engines supported
  • CURLINFO_COOKIELIST - All known cookies
  • CURLINFO_FTP_ENTRY_PATH - Entry path in FTP server
  • CURLINFO_APPCONNECT_TIME - Time in seconds it took from the start until the SSL/SSH connect/handshake to the remote host was completed
  • CURLINFO_CERTINFO - TLS certificate chain

  • CURLINFO_RTSP_SERVER_CSEQ - Next RTSP server CSeq
  • CURLINFO_RTSP_SESSION_ID - RTSP session ID
  • CURLINFO_CONTENT_LENGTH_DOWNLOAD_T - The content-length of the download. This is the value read from the Content-Type: field. -1 if the size isn't known
  • CURLINFO_CONTENT_LENGTH_UPLOAD_T - The specified size of the upload. -1 if the size isn't known
  • CURLINFO_HTTP_VERSION - The version used in the last HTTP connection. The return value will be one of the defined CURL_HTTP_VERSION_* constants or 0 if the version can't be determined
  • CURLINFO_PROTOCOL - The protocol used in the last HTTP connection. The returned value will be exactly one of the CURLPROTO_* values
  • CURLINFO_PROXY_SSL_VERIFYRESULT - The result of the certificate verification that was requested (using the CURLOPT_PROXY_SSL_VERIFYPEER option). Only used for HTTPS proxies
  • CURLINFO_SCHEME - The URL scheme used for the most recent connection
  • CURLINFO_SIZE_DOWNLOAD_T - Total number of bytes that were downloaded. The number is only for the latest transfer and will be reset again for each new transfer

  • "header_size"
  • "request_size"
  • "filetime"
  • "ssl_verify_result"
  • "redirect_count"

  • "certinfo"
  • "primary_ip"
  • "primary_port"

Examples

Example #1 curl_getinfo() example

<?php// Create a cURL handle$ch = curl_init('http://www.example.com/');// Executecurl_exec($ch);// Check if any error occurredif (!curl_errno($ch)) {  $info = curl_getinfo($ch);  echo 'Took ', $info['total_time'], ' seconds to send a request to ', $info['url'], "\n";}// Close handlecurl_close($ch);?>

Example #2 curl_getinfo() example with option parameter

<?php// Create a cURL handle$ch = curl_init('http://www.example.com/');// Executecurl_exec($ch);// Check HTTP status codeif (!curl_errno($ch)) {  switch ($http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE)) {    case 200:  # OK      break;    default:      echo 'Unexpected HTTP code: ', $http_code, "\n";  }}// Close handlecurl_close($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.
