PHP_curl_setopt

CURLOPT_SSL_VERIFYHOST: Pass a long if CURL should verify the Common name of the peer certificate in the SSL handshake. A value of 1 denotes that we should check for the existence of the common name, a value of 2 denotes that we should make sure it matches the provided hostname.

CURLOPT_NOPROGRESS: Set this option to a non-zero value if you don't want PHP to display a progress meter for CURL transfers.

注: PHP automatically sets this option to a non-zero parameter, this should only be changed for debugging purposes.

CURLOPT_LOW_SPEED_LIMIT: Pass a long as a parameter that contains the transfer speed in bytes per second that the transfer should be below during CURLOPT_LOW_SPEED_TIME seconds for PHP to consider too slow and abort.
Leabharlann CURLOPT_FOLLOWLOCATION: Set this option to a non-zero value to follow any "Location: " header that the server sends as a part of the HTTP header (note this is recursive, PHP will follow as many "Location: " headers that it is sent.)


CURLOPT_NOBODY: Set this option to a non-zero value if you don't want the body included with the output.

CURLOPT_FAILONERROR: Set this option to a non-zero value if you want PHP to fail silently if the HTTP code returned is greater than 300. The default behavior is to return the page normally, ignoring the code.

CURLOPT_TIMECONDITION: Pass a long as a parameter that defines how the CURLOPT_TIMEVALUE is treated. You can set this parameter to TIMECOND_IFMODSINCE or TIMECOND_ISUNMODSINCE. This is a HTTP-only feature.

CURLOPT_UPLOAD: Set this option to a non-zero value if you want PHP to prepare for an upload.

CURLOPT_POST: Set this option to a non-zero value if you want PHP to do a regular HTTP POST. This POST is a normal application/x-www-formurlencoded kind, most commonly used by HTML forms.

CURLOPT_NETRC: Set this option to a non-zero value and PHP will scan your ~./netrc file to find your username and password for the remote site that you're establishing a connection with.

CURLOPT_VERBOSE: Set this option to a non-zero value if you want CURL to report everything that is happening.

CURLOPT_HEADER: Set this option to a non-zero value if you want the header to be included in the output.
The value should be a long for the following options (specified in the option parameter):

CURLOPT_INFILESIZE: When you are uploading a file to a remote site, this option should be used to tell PHP what the expected size of the infile will be.

CURLOPT_SSL_VERIFYPEER: Pass a long that is set to a zero value to stop curl from verifying the peer's certificate (curl 7.10 starting setting this option to TRUE by default). Alternate certificates to verify against can be specified with the CURLOPT_CAINFO option (added in curl 7.9.8) or a certificate directory can be specified with the CURLOPT_CAPATH option. As of curl 7.10, curl installs a default bundle. CURLOPT_SSL_VERIFYHOST may also need to be set to 1 or 0 if CURLOPT_SSL_VERIFYPEER is disabled (it defaults to 2).
CURLOPT_MUTE: Set this option to a non-zero value and PHP will be completely silent with regards to the CURL functions.

CURLOPT_TIMEOUT: Pass a long as a parameter that contains the maximum time, in seconds, that you'll allow the CURL functions to take.

CURLOPT_SSLVERSION: Pass a long as a parameter that contains the SSL version (2 or 3) to use. By default PHP will try and determine this by itself, although, in some cases you must set this manually.

CURLOPT_RESUME_FROM: Pass a long as a parameter that contains the offset, in bytes, that you want the transfer to start from.

CURLOPT_CAINFO: Pass a filename of a file holding one or more certificates to verify the peer with. This only makes sense when used in combination with the CURLOPT_SSL_VERIFYPEER option.

CURLOPT_FTPLISTONLY: Set this option to a non-zero value and PHP will just list the names of an FTP directory.

CURLOPT_FTPAPPEND: Set this option to a non-zero value and PHP will append to the remote file instead of overwriting it.

CURLOPT_PUT: Set this option to a non-zero value to HTTP PUT a file. The file to PUT must be set with the CURLOPT_INFILE and CURLOPT_INFILESIZE.

The curl_setopt() function will set options for a CURL session identified by the ch parameter. The option parameter is the option you want to set, and the value is the value of the option given by the option.

CURLOPT_TIMEVALUE: Pass a long as a parameter that is the time in seconds since January 1st, 1970. The time will be used as specified by the CURLOPT_TIMECONDITION option, or by default the TIMECOND_IFMODSINCE will be used.

CURLOPT_RETURNTRANSFER: Pass a non-zero value if you want CURL to directly return the transfer instead of printing it out directly.

CURLOPT_LOW_SPEED_TIME: Pass a long as a parameter that contains the time in seconds that the transfer should be below the CURLOPT_LOW_SPEED_LIMIT for PHP to consider it too slow and abort.
