align: top;">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 are * CURL_IPRESOLVE_WHATEVER, * CURL_IPRESOLVE_V4, * CURL_IPRESOLVE_V6, by default * CURL_IPRESOLVE_WHATEVER. * * * Added in cURL 7.10.8. * * * * * * * * value should be a string for the following values of the option parameter: * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

Option	Set `value` to	Notes
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. *	* Might require an absolute path. *
CURLOPT_CAPATH	* A directory that holds multiple CA certificates. Use this option * alongside CURLOPT_SSL_VERIFYPEER. *	*
CURLOPT_COOKIE	* The contents of the "Cookie: " header to be * 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 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. * Note: * * Don't do this without making sure the server supports the custom * request method first. * * *	*
CURLOPT_EGDSOCKET	* Like CURLOPT_RANDOM_FILE, except a filename * to an Entropy Gathering Daemon socket. *	*
CURLOPT_ENCODING	* The contents of the "Accept-Encoding: " header. * This enables decoding of the response. Supported encodings are * "identity", "deflate", and * "gzip". If an empty string, "", * is set, a header containing all supported encoding types is sent. *	* 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. The * string may be a plain IP address, a hostname, a network * interface name (under Unix), or just a plain '-' to use the * systems default 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 the CURLOPT_SSLKEY * or CURLOPT_SSH_PRIVATE_KEYFILE private key. *	* Added in cURL 7.16.1. *
CURLOPT_KRB4LEVEL	* The KRB4 (Kerberos 4) security level. Any of the following values * (in order from least to most powerful) are valid: * "clear", * "safe", * "confidential", * "private".. * If the string does not match one of these, * "private" is used. Setting this option to NULL * will disable KRB4 security. Currently KRB4 security only works * with FTP transactions. *	*
CURLOPT_POSTFIELDS	* * The full data to post in a HTTP "POST" operation. * To post a file, prepend a filename with @ and * use the full path. The filetype can be explicitly specified by * following the filename with the type in the format * ';type=mimetype'. This parameter can either be * passed as a urlencoded string like 'para1=val1&para2=val2&...' * 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. * * * As of PHP 5.2.0, `value` must 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 using CURLFile. The * @ prefix can be disabled for safe passing of * values beginning with @ by setting the * CURLOPT_SAFE_UPLOAD option to *`TRUE``. ```*	*
CURLOPT_PROXY	* The HTTP proxy to tunnel requests through. *	*
CURLOPT_PROXYUSERPWD	* A username and password formatted as * "[username]:[password]" to use for the * connection to the proxy. *	*
CURLOPT_RANDOM_FILE	* A filename to be used to seed the random number generator for SSL. *	*
CURLOPT_RANGE	* Range(s) of data to retrieve in the format * "X-Y" where X or Y are optional. HTTP transfers * also support several intervals, separated with commas in the format * "X-Y,N-M". *	*
CURLOPT_REFERER	* The contents of the "Referer: " header to be used * in a HTTP request. *	*
CURLOPT_SSH_HOST_PUBLIC_KEY_MD5	* A string containing 32 hexadecimal digits. The string should be the * MD5 checksum of the remote host's public key, and libcurl will reject * the connection to the host unless the md5sums match. * This option is only for SCP and SFTP transfers. *	* Added in cURL 7.17.1. *
CURLOPT_SSH_PUBLIC_KEYFILE	* The file name for your public key. If not used, libcurl defaults to * $HOME/.ssh/id_dsa.pub if the HOME environment variable is set, * and just "id_dsa.pub" in the current directory if HOME is not set. *	* Added in cURL 7.16.1. *
CURLOPT_SSH_PRIVATE_KEYFILE	* The file name for your private key. If not used, libcurl defaults to * $HOME/.ssh/id_dsa if the HOME environment variable is set, * and just "id_dsa" in the current directory if HOME is not set. * If the file is password-protected, set the password with * CURLOPT_KEYPASSWD. *	* Added in cURL 7.16.1. *
CURLOPT_SSL_CIPHER_LIST	* A list of ciphers to use for SSL. For example, * RC4-SHA and TLSv1 are valid * cipher lists. *	*
CURLOPT_SSLCERT	* The name of a file containing a PEM formatted certificate. *	*
CURLOPT_SSLCERTPASSWD	* The password required to use the * CURLOPT_SSLCERT certificate. *	*
CURLOPT_SSLCERTTYPE	* The format of the certificate. Supported formats are * "PEM" (default), "DER", * and "ENG". *	* Added in cURL 7.9.3. *
CURLOPT_SSLENGINE	* The identifier for the crypto engine of the private SSL key * specified in CURLOPT_SSLKEY. *	*
CURLOPT_SSLENGINE_DEFAULT	* The identifier for the crypto engine used for asymmetric crypto * operations. *	*
CURLOPT_SSLKEY	* The name of a file containing a private SSL key. *	*
CURLOPT_SSLKEYPASSWD	* The secret password needed to use the private SSL key specified in * CURLOPT_SSLKEY. * Note: * * Since this option contains a sensitive password, remember to keep * the PHP script it is contained within safe. * * *	*
CURLOPT_SSLKEYTYPE	* The key type of the private SSL key specified in * CURLOPT_SSLKEY. Supported key types are * "PEM" (default), "DER", * and "ENG". *	*
CURLOPT_URL	* The URL to fetch. This can also be set when initializing a * session with {@see curl_init()}. *	*
CURLOPT_USERAGENT	* The contents of the "User-Agent: " header to be * used in a HTTP request. *	*
CURLOPT_USERPWD	* A username and password formatted as * "[username]:[password]" to use for the * connection. *	*
