Notes




CURLOPT_AUTOREFERER
TRUEto automatically set theReferer:field in requests where it follows aLocation:redirect.



CURLOPT_BINARYTRANSFER
TRUEto return the raw output whenCURLOPT_RETURNTRANSFERis used.
From PHP 5.1.3, this option has no effect: the raw output will always be returned whenCURLOPT_RETURNTRANSFERis used.


CURLOPT_COOKIESESSION
TRUEto mark this as a new cookie "session". It will force libcurl to ignore all cookies it is about to load that are "session cookies" from the previous session. By default, libcurl always stores and loads all cookies, independent if they are session cookies or not. Session cookies are cookies without expiry date and they are meant to be alive and existing for this "session" only.



CURLOPT_CERTINFO
TRUEto output SSL certification information toSTDERRon secure transfers.
Added in cURL 7.19.1. Available since PHP 5.3.2. RequiresCURLOPT_VERBOSEto be on to have an effect.

Added in 7.15.2. Available since PHP 5.5.0.


CURLOPT_CRLF
TRUEto convert Unix newlines to CRLF newlines on transfers.



CURLOPT_DNS_USE_GLOBAL_CACHE
TRUEto use a global DNS cache. This option is not thread-safe and is enabled by default.

TRUEto fail verbosely if the HTTP code returned is greater than or equal to 400. The default behavior is to return the page normally, ignoring the code.



CURLOPT_SSL_FALSESTART
TRUEto enable TLS false start.
Added in cURL 7.42.0. Available since PHP 7.0.7.


CURLOPT_FILETIME
TRUEto attempt to retrieve the modification date of the remote document. This value can be retrieved using theCURLINFO_FILETIMEoption withcurl_getinfo().



CURLOPT_FOLLOWLOCATION
TRUEto follow any"Location: "header that the server sends as part of the HTTP header (note this is recursive, PHP will follow as many"Location: "headers that it is sent, unlessCURLOPT_MAXREDIRSis set).



CURLOPT_FORBID_REUSE
TRUEto force the connection to explicitly close when it has finished processing, and not be pooled for reuse.



CURLOPT_FRESH_CONNECT
TRUEto force the use of a new connection instead of a cached one.



CURLOPT_FTP_USE_EPRT
TRUEto use EPRT (and LPRT) when doing active FTP downloads. UseFALSEto disable EPRT and LPRT and use PORT only.



CURLOPT_FTP_USE_EPSV
TRUEto first try an EPSV command for FTP transfers before reverting back to PASV. Set toFALSEto disable EPSV.



CURLOPT_FTP_CREATE_MISSING_DIRS
TRUEto create missing directories when an FTP operation encounters a path that currently doesn't exist.



CURLOPT_FTPAPPEND
TRUEto append to the remote file instead of overwriting it.



CURLOPT_TCP_NODELAY

TRUEto reset the HTTP request method to GET. Since GET is the default, this is only necessary if the request method has been changed.



CURLOPT_HTTPPROXYTUNNEL
TRUEto tunnel through a given HTTP proxy.



CURLOPT_MUTE
TRUEto be completely silent with regards to the cURL functions.
Removed in cURL 7.15.5 (You can use CURLOPT_RETURNTRANSFER instead)


CURLOPT_NETRC
TRUEto scan the~/.netrcfile to find a username and password for the remote site that a connection is being established with.



CURLOPT_NOBODY
TRUEto exclude the body from the output. Request method is then set to HEAD. Changing this toFALSEdoes not change it to GET.



CURLOPT_NOPROGRESS

TRUEto disable the progress meter for cURL transfers.



Note:


PHP automatically sets this option toTRUE, this should only be changed for debugging purposes.







CURLOPT_NOSIGNAL

CURLOPT_BUFFERSIZE
The size of the buffer to use for each read. There is no guarantee this request will be fulfilled, however.
Added in cURL 7.10.


CURLOPT_CLOSEPOLICY

Note:


This option is deprecated, as it was never implemented in cURL and never had any effect.




Removed in PHP 5.6.0.


CURLOPT_CONNECTTIMEOUT
The number of seconds to wait while trying to connect. Use 0 to wait indefinitely.



CURLOPT_CONNECTTIMEOUT_MS
The number of milliseconds to wait while trying to connect. Use 0 to wait indefinitely. If libcurl is built to use the standard system name resolver, that portion of the connect will still use full-second resolution for timeouts with a minimum timeout allowed of one second.
Added in cURL 7.16.2. Available since PHP 5.2.3.


CURLOPT_DNS_CACHE_TIMEOUT
The number of seconds to keep DNS entries in memory. This option is set to 120 (2 minutes) by default.

Added in cURL 7.12.2.


CURLOPT_HEADEROPT
How to deal with headers. One of the following constants:CURLHEADER_UNIFIED: the headers specified inCURLOPT_HTTPHEADERwill be used in requests both to servers and proxies. With this option enabled,CURLOPT_PROXYHEADERwill not have any effect.CURLHEADER_SEPARATE: makesCURLOPT_HTTPHEADERheaders only get sent to a server and not to a proxy. Proxy headers must be set withCURLOPT_PROXYHEADERto get used. Note that if a non-CONNECT request is sent to a proxy, libcurl will send both server headers and proxy headers. When doing CONNECT, libcurl will sendCURLOPT_PROXYHEADERheaders only to the proxy and thenCURLOPT_HTTPHEADERheaders only to the server.Defaults toCURLHEADER_SEPARATEas of cURL 7.42.1, andCURLHEADER_UNIFIEDbefore.
Added in cURL 7.37.0. Available since PHP 7.0.7.


CURLOPT_HTTP_VERSION
CURL_HTTP_VERSION_NONE(default, lets CURL decide which version to use),CURL_HTTP_VERSION_1_0(forces HTTP/1.0), orCURL_HTTP_VERSION_1_1(forces HTTP/1.1).



CURLOPT_HTTPAUTH

The HTTP authentication method(s) to use. The options are:CURLAUTH_BASIC,CURLAUTH_DIGEST,CURLAUTH_GSSNEGOTIATE,CURLAUTH_NTLM,CURLAUTH_ANY, andCURLAUTH_ANYSAFE.


The bitwise|(or) operator can be used to combine more than one method. If this is done, cURL will poll the server to see what methods it supports and pick the best one.


CURLAUTH_ANYis an alias forCURLAUTH_BASIC | CURLAUTH_DIGEST | CURLAUTH_GSSNEGOTIATE | CURLAUTH_NTLM.


CURLAUTH_ANYSAFEis an alias forCURLAUTH_DIGEST | CURLAUTH_GSSNEGOTIATE | CURLAUTH_NTLM.






CURLOPT_INFILESIZE
The expected size, in bytes, of the file when uploading a file to a remote site. Note that using this option will not stop libcurl from sending more data, as exactly what is sent depends onCURLOPT_READFUNCTION.



CURLOPT_LOW_SPEED_LIMIT
The transfer speed, in bytes per second, that the transfer should be below during the count ofCURLOPT_LOW_SPEED_TIMEseconds before PHP considers the transfer too slow and aborts.



CURLOPT_LOW_SPEED_TIME
The number of seconds the transfer speed should be belowCURLOPT_LOW_SPEED_LIMITbefore PHP considers the transfer too slow and aborts.



CURLOPT_MAXCONNECTS
The maximum amount of persistent connections that are allowed. When the limit is reached,CURLOPT_CLOSEPOLICYis used to determine which connection to close.



CURLOPT_MAXREDIRS
The maximum amount of HTTP redirections to follow. Use this option alongsideCURLOPT_FOLLOWLOCATION.



CURLOPT_PORT
An alternative port number to connect to.



CURLOPT_POSTREDIR
A bitmask of 1 (301 Moved Permanently), 2 (302 Found) and 4 (303 See Other) if the HTTP POST method should be maintained whenCURLOPT_FOLLOWLOCATIONis set and a specific type of redirect occurs.
Added in cURL 7.19.1. Available since PHP 5.3.2.


CURLOPT_PROTOCOLS

Bitmask ofCURLPROTO_*values. If used, this bitmask limits what protocols libcurl may use in the transfer. This allows you to have a libcurl built to support a wide range of protocols but still limit specific transfers to only be allowed to use a subset of them. By default libcurl will accept all protocols it supports. See alsoCURLOPT_REDIR_PROTOCOLS.


Valid protocol options are:CURLPROTO_HTTP,CURLPROTO_HTTPS,CURLPROTO_FTP,CURLPROTO_FTPS,CURLPROTO_SCP,CURLPROTO_SFTP,CURLPROTO_TELNET,CURLPROTO_LDAP,CURLPROTO_LDAPS,CURLPROTO_DICT,CURLPROTO_FILE,CURLPROTO_TFTP,CURLPROTO_ALL



Added in cURL 7.19.4.


CURLOPT_PROXYAUTH
The HTTP authentication method(s) to use for the proxy connection. Use the same bitmasks as described inCURLOPT_HTTPAUTH. For proxy authentication, onlyCURLAUTH_BASICandCURLAUTH_NTLMare currently supported.
Added in cURL 7.10.7.


CURLOPT_PROXYPORT
The port number of the proxy to connect to. This port number can also be set inCURLOPT_PROXY.



CURLOPT_PROXYTYPE
EitherCURLPROXY_HTTP(default),CURLPROXY_SOCKS4,CURLPROXY_SOCKS5,CURLPROXY_SOCKS4AorCURLPROXY_SOCKS5_HOSTNAME.
Added in cURL 7.10.


CURLOPT_REDIR_PROTOCOLS
Bitmask ofCURLPROTO_*values. If used, this bitmask limits what protocols libcurl may use in a transfer that it follows to in a redirect whenCURLOPT_FOLLOWLOCATIONis enabled. This allows you to limit specific transfers to only be allowed to use a subset of protocols in redirections. By default libcurl will allow all protocols except for FILE and SCP. This is a difference compared to pre-7.19.4 versions which unconditionally would follow to all protocols supported. See alsoCURLOPT_PROTOCOLSfor protocol constant values.
Added in cURL 7.19.4.


CURLOPT_RESUME_FROM
The offset, in bytes, to resume a transfer from.



CURLOPT_SSL_OPTIONS
Set SSL behavior options, which is a bitmask of any of the following constants:CURLSSLOPT_ALLOW_BEAST: do not attempt to use any workarounds for a security flaw in the SSL3 and TLS1.0 protocols.CURLSSLOPT_NO_REVOKE: disable certificate revocation checks for those SSL backends where such behavior is present.
Added in cURL 7.25.0. Available since PHP 7.0.7.


CURLOPT_SSL_VERIFYHOST
1 to check the existence of a common name in the SSL peer certificate. 2 to check the existence of a common name and also verify that it matches the hostname provided. In production environments the value of this option should be kept at 2 (default value).
Support for value 1 removed in cURL 7.28.1


CURLOPT_SSLVERSION
One ofCURL_SSLVERSION_DEFAULT(0),CURL_SSLVERSION_TLSv1(1),CURL_SSLVERSION_SSLv2(2),CURL_SSLVERSION_SSLv3(3),CURL_SSLVERSION_TLSv1_0(4),CURL_SSLVERSION_TLSv1_1(5) orCURL_SSLVERSION_TLSv1_2(6).

Note:


Your best bet is to not set this and let it use the default. Setting it to 2 or 3 is very dangerous given the known vulnerabilities in SSLv2 and SSLv3.







CURLOPT_STREAM_WEIGHT
Set the numerical stream weight (a number between 1 and 256).
Added in cURL 7.46.0. Available since PHP 7.0.7.


CURLOPT_TIMECONDITION
HowCURLOPT_TIMEVALUEis treated. UseCURL_TIMECOND_IFMODSINCEto return the page only if it has been modified since the time specified inCURLOPT_TIMEVALUE. If it hasn't been modified, a"304 Not Modified"header will be returned assumingCURLOPT_HEADERisTRUE. UseCURL_TIMECOND_IFUNMODSINCEfor the reverse effect.CURL_TIMECOND_IFMODSINCEis the default.



CURLOPT_TIMEOUT
The maximum number of seconds to allow cURL functions to execute.



CURLOPT_TIMEOUT_MS
The maximum number of milliseconds to allow cURL functions to execute. If libcurl is built to use the standard system name resolver, that portion of the connect will still use full-second resolution for timeouts with a minimum timeout allowed of one second.
Added in cURL 7.16.2. Available since PHP 5.2.3.


CURLOPT_TIMEVALUE
The time in seconds since January 1st, 1970. The time will be used byCURLOPT_TIMECONDITION. By default,CURL_TIMECOND_IFMODSINCEis used.



CURLOPT_MAX_RECV_SPEED_LARGE
If a download exceeds this speed (counted in bytes per second) on cumulative average during the transfer, the transfer will pause to keep the average rate less than or equal to the parameter value. Defaults to unlimited speed.
Added in cURL 7.15.5. Available since PHP 5.4.0.


CURLOPT_MAX_SEND_SPEED_LARGE
If an upload exceeds this speed (counted in bytes per second) on cumulative average during the transfer, the transfer will pause to keep the average rate less than or equal to the parameter value. Defaults to unlimited speed.
Added in cURL 7.15.5. Available since PHP 5.4.0.


CURLOPT_SSH_AUTH_TYPES
A bitmask consisting of one or more ofCURLSSH_AUTH_PUBLICKEY,CURLSSH_AUTH_PASSWORD,CURLSSH_AUTH_HOST,CURLSSH_AUTH_KEYBOARD. Set toCURLSSH_AUTH_ANYto let libcurl pick one.
Added in cURL 7.16.1.


CURLOPT_IPRESOLVE
Allows an application to select what kind of IP addresses to use when resolving host names. This is only interesting when using host names that resolve addresses using more than one version of IP, possible values areCURL_IPRESOLVE_WHATEVER,CURL_IPRESOLVE_V4,CURL_IPRESOLVE_V6, by defaultCURL_IPRESOLVE_WHATEVER.
Added in cURL 7.10.8.


CURLOPT_FTP_FILEMETHOD
Tell curl which method to use to reach a file on a FTP(S) server. Possible values areCURLFTPMETHOD_MULTICWD,CURLFTPMETHOD_NOCWDandCURLFTPMETHOD_SINGLECWD.

The name of a file to save all internal cookies to when the handle is closed, e.g. after a call to curl_close.



CURLOPT_CUSTOMREQUEST

A custom request method to use instead of"GET"or"HEAD"when doing a HTTP request. This is useful for doing"DELETE"or other, more obscure HTTP requests. Valid values are things like"GET","POST","CONNECT"and so on; i.e. Do not enter a whole HTTP request line here. For instance, entering"GET /index.html HTTP/1.0/r/n/r/n"would be incorrect.

Added in cURL 7.10.


CURLOPT_FTPPORT
The value which will be used to get the IP address to use for the FTP "PORT" instruction. The "PORT" instruction tells the remote server to connect to our specified IP address.

CURLOPT_INTERFACE
The name of the outgoing network interface to use. This can be an interface name, an IP address or a host name.



CURLOPT_KEYPASSWD
The password required to use theCURLOPT_SSLKEYorCURLOPT_SSH_PRIVATE_KEYFILEprivate key.

Ifvalueis an array, theContent-Typeheader will be set tomultipart/form-data.As of PHP 5.2.0,valuemust be an array if files are passed to this option with the@prefix.As of PHP 5.5.0, the@prefix is deprecated and files can be sent usingCURLFile. The@prefix can be disabled for safe passing of values beginning with@by setting theCURLOPT_SAFE_UPLOADoption toTRUE.



CURLOPT_PRIVATE
