CURLOPT_ABSTRACT_UNIX_SOCKET |
Enables the use of an abstract Unix domain socket instead of
establishing a TCP connection to a host and sets the path to
the given string. This option shares the same semantics
as CURLOPT_UNIX_SOCKET_PATH . These two options
share the same storage and therefore only one of them can be set
per handle.
|
Available since PHP 7.3.0 and cURL 7.53.0
|
CURLOPT_ALTSVC |
Pass the filename for cURL to use as the Alt-Svc cache file to read existing cache contents from and
possibly also write it back to a after a transfer, unless CURLALTSVC_READONLYFILE
is set via CURLOPT_ALTSVC_CTRL .
|
|
CURLOPT_ALTSVC_CTRL |
Populate the bitmask with the correct set of features to instruct cURL how to handle Alt-Svc for the
transfers using this handle. cURL only accepts Alt-Svc headers over HTTPS. It will also only complete
a request to an alternative origin if that origin is properly hosted over HTTPS.
Setting any bit will enable the alt-svc engine. The options are:
CURLALTSVC_H1 ,
CURLALTSVC_H2 ,
CURLALTSVC_H3 , and
CURLALTSVC_READONLYFILE .
|
|
CURLOPT_AWS_SIGV4 |

This option overrides any other authentication types that have been set in
CURLOPT_HTTPAUTH . This method cannot be combined with other authentication types.
|
|
CURLOPT_CAINFO |
The name of a file holding one or more certificates to verify the
peer with. This only makes sense when used in combination with
CURLOPT_SSL_VERIFYPEER .

peer with. This option overrides CURLOPT_CAINFO .

used in the HTTP request.
Note that multiple cookies are separated with a semicolon followed
by a space (e.g., "fruit=apple; colour=red ")
|
|
CURLOPT_COOKIEFILE |
The name of the file containing the cookie data. The cookie file can
be in Netscape format, or just plain HTTP-style headers dumped into
a file.
If the name is an empty string, no cookies are loaded, but cookie
handling is still enabled.
|
|
CURLOPT_COOKIEJAR |
The name of a file to save all internal cookies to when the
handle's destructor is called.
Увага
As of PHP 8.0.0, curl_close() is a no-op
and does not destroy the handle.
If cookies need to be written prior to the handle being automatically
destroyed, call unset() on the handle.
|
|
CURLOPT_COOKIELIST |
A cookie string (i.e. a single line in Netscape/Mozilla format, or a regular
HTTP-style Set-Cookie header) adds that single cookie to the internal cookie store.
"ALL" erases all cookies held in memory.
"SESS" erases all session cookies held in memory.
"FLUSH" writes all known cookies to the file specified by CURLOPT_COOKIEJAR .
"RELOAD" loads all cookies from the files specified by CURLOPT_COOKIEFILE .
|
Available since cURL 7.14.1.
|
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.
Зауваження:
Don't do this without making sure the server supports the custom
request method first.

interface name (under Unix), or just a plain '-' to use the
systems default IP address.
|
|
CURLOPT_HSTS |
HSTS (HTTP Strict Transport Security) cache file name.
|
|
CURLOPT_HSTS_CTRL |
Controls HSTS (HTTP Strict Transport Security) behavior. Populate the bitmask with the correct set of

or as an array with the field name as key and field data as value.
If value is an array, the
Content-Type header will be set to
multipart/form-data .
Files can be sent using CURLFile or CURLStringFile,
in which case value must be an array.
|
|
CURLOPT_PRIVATE |
Any data that should be associated with this cURL handle. This data
can subsequently be retrieved with the

IP address to be used as the preproxy that curl connects to before
it connects to the HTTP(S) proxy specified in the
CURLOPT_PROXY option for the upcoming request.
The preproxy can only be a SOCKS proxy and it should be prefixed with
[scheme]:// to specify which kind of socks is used.
A numerical IPv6 address must be written within [brackets].
Setting the preproxy to an empty string explicitly disables the use of a preproxy.
To specify port number in this string, append :[port]
