curl_setopt parameter Setting Summary

The most important function in the Curl function library is curl_setopt (), it can customize the HTTP request by setting the options defined by the Curl function library

How to use:

BOOL curl_setopt (int ch, string option, mixed value)

The curl_setopt () function sets options for a curl session. The option parameter is the setting that you want, and value is the one given by this choice.

The values of the following options are used as long shapes (specified in the option parameter):

curlopt_infilesize:When you upload a file to a remote site, this option tells PHP the size of your upload file.

Curlopt_verbose:If you want curl to report every unexpected thing, set this option to a value other than 0.

Curlopt_header:If you want to include a header in the output, set this option to a value other than 0.

curlopt_noprogress:If you do not have PHP display a process bar for the Curl transfer, set this option to a value other than 0.
Note: PHP automatically sets this option to a value other than 0, you should only change this option for debugging purposes.

Curlopt_nobody:If you do not want to include the body part in the output, set this option to a value other than 0.

Curlopt_failonerror:If you want PHP to not display when an error occurs (HTTP code returns greater than or equal to 300), set this option to one person and not 0 value. The default behavior is to return a normal page, ignoring the code.

Curlopt_upload:If you want PHP to prepare for uploading, set this option to a value other than 0.

Curlopt_post:If you want PHP to do a regular HTTP POST, set this option to a value other than 0. This post is an ordinary application/x-www-from-urlencoded type, most of which is used by HTML forms

curlopt_ftplistonly:Setting this option to a value other than 0, PHP lists the list of directory names for FTP.

Curlopt_ftpappend: To set this option to a value other than 0, PHP will apply the remote file instead of overwriting it.

CURLOPT_NETRC:Set this option to a value other than 0, PHP will look in your ~./netrc file for the user name and password of the remote site you want to connect to.

curlopt_followlocation://Set this option to a header that is not a value of 0 (like ' Location: ') and the server sends it as part of the HTTP header (note that this is recursive and PHP will send the header as ' location: ').

Curlopt_put:Set this option to use HTTP to upload a file for a value other than 0. To upload this file you must set the Curlopt_infile and Curlopt_infilesize options.

Curlopt_mute://Set this option to a value other than 0, and PHP will be completely silent for the curl function.

curlopt_low_speed_limit://Sets a long shaping number that controls how many bytes are transferred.
Curlopt_low_speed_time:Sets a long shape number that controls how many seconds to transmit curlopt_low_speed_limit the specified number of bytes.

Curlopt_resume_from:Pass a long shaping parameter that contains the byte offset address (the start form you want to transfer to).

curlopt_sslversion:Pass a long parameter that contains the SSL version. The default PHP will be determined by its own efforts, and in more security you must set it up manually.

Curlopt_timevalue:Pass a number of seconds from 1970-1-1 onwards to the present. This time will be used by the Curlopt_timevalue option as the specified value, or by default timecond_ifmodsince.
