PARAMETERS

ch

A cURL handle returned by curl_init().

opt

This may be one of the following constants:

CONSTANT DESCRIPTION

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_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_SIZE_DOWNLOAD Total number of bytes downloaded
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_CONDITION_UNMET Info on unmet time conditional
CURLINFO_RTSP_CLIENT_CSEQ Next RTSP client CSeq
CURLINFO_RTSP_CSEQ_RECV Recently received CSeq
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
CURLINFO_SIZE_UPLOAD_T Total number of bytes that were uploaded
CURLINFO_SPEED_DOWNLOAD_T The average download speed in bytes/second that curl measured for the complete download
CURLINFO_SPEED_UPLOAD_T The average upload speed in bytes/second that curl measured for the complete upload
CURLINFO_APPCONNECT_TIME_T Time, in microseconds, it took from the start until the SSL/SSH connect/handshake to the remote host was completed
CURLINFO_CONNECT_TIME_T Total time taken, in microseconds, from the start until the connection to the remote host (or proxy) was completed
CURLINFO_FILETIME_T Remote time of the retrieved document (as Unix timestamp), an alternative to CURLINFO_FILETIME to allow systems with 32 bit long variables to extract dates outside of the 32bit timestamp range
CURLINFO_NAMELOOKUP_TIME_T Time in microseconds from the start until the name resolving was completed
CURLINFO_PRETRANSFER_TIME_T Time taken from the start until the file transfer is just about to begin, in microseconds
CURLINFO_REDIRECT_TIME_T Total time, in microseconds, it took for all redirection steps include name lookup, connect, pretransfer and transfer before final transaction was started
CURLINFO_STARTTRANSFER_TIME_T Time, in microseconds, it took from the start until the first byte is received
CURLINFO_TOTAL_TIME_T Total time in microseconds for the previous transfer, including name resolving, TCP connect etc.

RETURN

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.
