curl_setopt
(PHP 4 >= 4.0.2)
curl_setopt -- 为CURL调用设置一个选项
描述
 
bool curl_setopt (int ch, string option, mixed value)
 
curl_setopt()函数将为一个CURL会话设置选项。option参数是你想要的设置,value是这个选项给定的值。
下列选项的值将被作为长整形使用(在option参数中指定):
 
CURLOPT_INFILESIZE: 当你上传一个文件到远程站点,这个选项告诉PHP你上传文件的大小。
CURLOPT_VERBOSE: 如果你想CURL报告每一件意外的事情,设置这个选项为一个非零值。
CURLOPT_HEADER: 如果你想把一个头包含在输出中,设置这个选项为一个非零值。
CURLOPT_NOPROGRESS: 如果你不会PHP为CURL传输显示一个进程条,设置这个选项为一个非零值。
注意:PHP自动设置这个选项为非零值,你应该仅仅为了调试的目的来改变这个选项。
CURLOPT_NOBODY: 如果你不想在输出中包含body部分,设置这个选项为一个非零值。
CURLOPT_FAILONERROR: 如果你想让PHP在发生错误(HTTP代码返回大于等于300)时,不显示,设置这个选项为一人非零值。默认行为是返回一个正常页,忽略代码。
CURLOPT_UPLOAD: 如果你想让PHP为上传做准备,设置这个选项为一个非零值。
CURLOPT_POST: 如果你想PHP去做一个正规的HTTP POST,设置这个选项为一个非零值。这个POST是普通的 application/x-www-from-urlencoded 类型,多数被HTML表单使用。
CURLOPT_FTPLISTONLY: 设置这个选项为非零值,PHP将列出FTP的目录名列表。
CURLOPT_FTPAPPEND: 设置这个选项为一个非零值,PHP将应用远程文件代替覆盖它。
CURLOPT_NETRC: 设置这个选项为一个非零值,PHP将在你的 ~./netrc 文件中查找你要建立连接的远程站点的用户名及密码。
CURLOPT_FOLLOWLOCATION: 设置这个选项为一个非零值(象 'Location: ')的头,服务器会把它当做HTTP头的一部分发送(注意这是递归的,PHP将发送形如 'Location: '的头)。
CURLOPT_PUT: 设置这个选项为一个非零值去用HTTP上传一个文件。要上传这个文件必须设置CURLOPT_INFILE和CURLOPT_INFILESIZE选项.
CURLOPT_MUTE: 设置这个选项为一个非零值,PHP对于CURL函数将完全沉默。
CURLOPT_TIMEOUT: 设置一个长整形数,作为最大延续多少秒。
CURLOPT_LOW_SPEED_LIMIT: 设置一个长整形数,控制传送多少字节。
CURLOPT_LOW_SPEED_TIME: 设置一个长整形数,控制多少秒传送CURLOPT_LOW_SPEED_LIMIT规定的字节数。
CURLOPT_RESUME_FROM: 传递一个包含字节偏移地址的长整形参数,(你想转移到的开始表单)。
CURLOPT_SSLVERSION: 传递一个包含SSL版本的长参数。默认PHP将被它自己努力的确定,在更多的安全中你必须手工设置。
CURLOPT_TIMECONDITION: 传递一个长参数,指定怎么处理CURLOPT_TIMEVALUE参数。你可以设置这个参数为TIMECOND_IFMODSINCE 或 TIMECOND_ISUNMODSINCE。这仅用于HTTP。
CURLOPT_TIMEVALUE: 传递一个从1970-1-1开始到现在的秒数。这个时间将被CURLOPT_TIMEVALUE选项作为指定值使用,或被默认TIMECOND_IFMODSINCE使用。
下列选项的值将被作为字符串:
 
CURLOPT_URL: 这是你想用PHP取回的URL地址。你也可以在用curl_init()函数初始化时设置这个选项。
CURLOPT_USERPWD: 传递一个形如[username]:[password]风格的字符串,作用PHP去连接。
CURLOPT_PROXYUSERPWD: 传递一个形如[username]:[password] 格式的字符串去连接HTTP代理。
CURLOPT_RANGE: 传递一个你想指定的范围。它应该是'X-Y'格式,X或Y是被除外的。HTTP传送同样支持几个间隔,用逗句来分隔(X-Y,N-M)。
CURLOPT_POSTFIELDS: 传递一个作为HTTP “POST”操作的所有数据的字符串。
CURLOPT_REFERER: 在HTTP请求中包含一个'referer'头的字符串。
CURLOPT_USERAGENT: 在HTTP请求中包含一个'user-agent'头的字符串。
CURLOPT_FTPPORT: 传递一个包含被ftp 'POST'指令使用的IP地址。这个POST指令告诉远程服务器去连接我们指定的IP地址。 这个字符串可以是一个IP地址,一个主机名,一个网络界面名(在UNIX下),或是‘-'(使用系统默认IP地址)。
CURLOPT_COOKIE: 传递一个包含HTTP cookie的头连接。
CURLOPT_SSLCERT: 传递一个包含PEM格式证书的字符串。
CURLOPT_SSLCERTPASSWD: 传递一个包含使用CURLOPT_SSLCERT证书必需的密码。
CURLOPT_COOKIEFILE: 传递一个包含cookie数据的文件的名字的字符串。这个cookie文件可以是Netscape格式,或是堆存在文件中的HTTP风格的头。
CURLOPT_CUSTOMREQUEST: 当进行HTTP请求时,传递一个字符被GET或HEAD使用。为进行DELETE或其它操作是有益的,更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.
注意: 在确认你的服务器支持命令先不要去这样做。
下列的选项要求一个文件描述(通过使用fopen()函数获得):
 
CURLOPT_FILE: 这个文件将是你放置传送的输出文件,默认是STDOUT.
CURLOPT_INFILE: 这个文件是你传送过来的输入文件。
CURLOPT_WRITEHEADER: 这个文件写有你输出的头部分。
CURLOPT_STDERR: 这个文件写有错误而不是stderr。

$handles = curl_exec($ch);
//下面是替换,可以结合服务器伪静态设置
$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);
