curl_setopt
(PHP 4 >= 4.0.2)
curl_setopt -- Set an option for CURL call
Description

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

The curl_setopt() function will set options for a CURL session. The option parameter is the setting you want, and value is the value given by this option.
The values ​​of the following options will be used as long integers (specified in the option parameter):

CURLOPT_INFILESIZE: When you upload a file to the remote site, this option tells PHP the size of the file you uploaded.
CURLOPT_VERBOSE: If you want CURL to report every unexpected event, set this option to a non-zero value.
CURLOPT_HEADER: If you want to include a header in the output, set this option to a non-zero value.
CURLOPT_NOPROGRESS: If you do not want PHP to display a progress bar for CURL transfers, set this option to a non-zero value.
Note: PHP automatically sets this option to a non-zero value, 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 non-zero value.
CURLOPT_FAILONERROR: If you want PHP not to display when an error occurs (HTTP code return greater than or equal to 300), set this option to a non-zero value. The default behavior is to return a normal page and ignore the code.
CURLOPT_UPLOAD: If you want PHP to prepare for uploading, set this option to a non-zero value.
CURLOPT_POST: If you want PHP to do a regular HTTP POST, set this option to a non-zero value. This POST is of the ordinary application/x-www-from-urlencoded type, mostly used by HTML forms.
CURLOPT_FTPLISTONLY: Set this option to a non-zero value and PHP will list the directory names for FTP.
CURLOPT_FTPAPPEND: Set this option to a non-zero value and PHP will apply the remote file instead of overwriting it.
CURLOPT_NETRC: Set this option to a non-zero value and PHP will look in your ~./netrc file for the username and password of the remote site you want to connect to.
CURLOPT_FOLLOWLOCATION: Set this option to a non-zero header (like 'Location: ') and the server will send it as part of the HTTP header (note that this is recursive, PHP will send a header of the form 'Location: ' head).
CURLOPT_PUT: Set this option to a non-zero value to upload a file using HTTP. To upload this file you must set the CURLOPT_INFILE and CURLOPT_INFILESIZE options.
CURLOPT_MUTE: Set this option to a non-zero value and PHP will be completely silent for the CURL function.
CURLOPT_TIMEOUT: Set a long integer as the maximum number of seconds.
CURLOPT_LOW_SPEED_LIMIT: Set a long integer to control how many bytes are transmitted.
CURLOPT_LOW_SPEED_TIME: Set a long integer to control how many seconds to transmit the number of bytes specified by CURLOPT_LOW_SPEED_LIMIT.
CURLOPT_RESUME_FROM: Pass a long parameter containing the byte offset address (the start form you want to transfer to).
CURLOPT_SSLVERSION: Pass a long parameter containing the SSL version. By default PHP will do its own hard work, in more security you have to set it manually.
CURLOPT_TIMECONDITION: Pass a long parameter to specify how to handle the CURLOPT_TIMEVALUE parameter. You can set this parameter to TIMECOND_IFMODSINCE or TIMECOND_ISUNMODSINCE. This is only for HTTP.
CURLOPT_TIMEVALUE: Pass a number of seconds from 1970-1-1 to now. This time will be used as the specified value by the CURLOPT_TIMEVALUE option, or by the default TIMECOND_IFMODSINCE.
The values ​​of the following options will be treated as strings:

CURLOPT_URL: This is the URL address you want to retrieve using PHP. You can also set this option during initialization with the curl_init() function.
CURLOPT_USERPWD: Pass a string in the form of [username]:[password] and use PHP to connect.
CURLOPT_PROXYUSERPWD: Pass a string in the format [username]:[password] to connect to the HTTP proxy.
CURLOPT_RANGE: Pass a range you want to specify. It should be in 'X-Y' format, with X or Y being excluded. HTTP transfers also support several intervals, separated by commas (X-Y,N-M).
CURLOPT_POSTFIELDS: Pass a string containing all the data as an HTTP "POST" operation.
CURLOPT_REFERER: A string containing a 'referer' header in the HTTP request.
CURLOPT_USERAGENT: A string containing a 'user-agent' header in the HTTP request.
CURLOPT_FTPPORT: Pass an IP address containing the IP address used by the ftp 'POST' command. This POST command tells the remote server to connect to the IP address we specified. This string can be an IP address, a host name, a network interface name (under UNIX), or '-' (use the system default IP address).
CURLOPT_COOKIE: Pass a header connection containing an HTTP cookie.
CURLOPT_SSLCERT: Pass a string containing the certificate in PEM format.
CURLOPT_SSLCERTPASSWD: Pass a password containing the necessary password to use the CURLOPT_SSLCERT certificate.
CURLOPT_COOKIEFILE: Pass a string containing the name of the file containing cookie data. This cookie file can be in Netscape format, or it can be a stack of HTTP-style headers stored in the file.
CURLOPT_CUSTOMREQUEST: When making an HTTP request, pass a character to be used by GET or HEAD.Pass a string to be used instead of GET or HEAD when doing an HTTP request. This is useful for doing or another, more obscure, HTTP request.
Note: Before confirming you Don't do this yet if your server supports commands.
The following options require a file description (obtained by using the fopen() function):

CURLOPT_FILE: This file will be the output file you place the transfer. The default is STDOUT.
CURLOPT_INFILE: This file It is the input file you sent.
CURLOPT_WRITEHEADER: This file contains the header part of your output.
CURLOPT_STDERR: This file has errors written instead of stderr.

Example code: Tested

Copy code The code is as follows:

@header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
@header("Last-Modified: " . gmdate("D, d M Y H:i:s ") . " GMT");
// always modified
@header("Cache-Control: no-store, no-cache, must-revalidate"); // HTTP/1.1
@header ("Cache-Control: post-check=0, pre-check=0", false);
@header("Pragma: no-cache");
@header("content-type:text/ html; charset=utf-8");

$url = 'http://s.jb51.net';
$querystring = $_SERVER["QUERY_STRING"];
$currentUrl = $_SERVER['SERVER_NAME'];
if($querystring != '') $querystring = $querystring . "&";
$querystring = $querystring . "SiteURL=" . $currentUrl;

if($querystring != '')
{
$url = $url . "?" . $querystring;
}

$ch = curl_init();
$timeout = 60; // set to zero for no timeout
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch , CURLOPT_CONNECTTIMEOUT, $timeout);
$handles = curl_exec($ch);
//The following are replacements, which can be combined with server pseudo-static settings
$handles = preg_replace("/?page=([0 -9]+)&categoryId=([0-9]+)/i","/fenlei/category-$1-$2.html",$handles);
$handles = preg_replace("/?categoryId=( [0-9]+)/i","/fenlei/category--$1.html",$handles);
$handles = preg_replace("/?page=([0-9]+)/i ","/fenlei/category-$1.html",$handles);
$handles = preg_replace("/infodetail.aspx?ID=([0-9]+)/i","/fenlei/$1 .html",$handles);
$handles = str_replace("infolist.aspx","/fenlei/index.html",$handles);
$handles = str_replace("unionlist.aspx"," unionlist.html",$handles);
echo $handles;

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.
