windows 系统中socket扩展
windows 下可以直接修改php.ini 文件 去掉extension=php_sockets.dll 前面的分号重启就OK了
在linux下给PHP安装socket扩展
| 代码如下 |
复制代码 |
|
#cd /home/php5.2.1/ext/sockets
#/server/php/bin/phpize
#./configure --prefix=/usr/local/php/lib --with-php-config=/server/php/bin/php-config --enable-sockets
#make
#make install
再修改/usr/local/php/etc/php.ini文件
#extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20090626/" (php5.4版本以上不用加扩展路径)
extension=sockets.so
|
重启apache
好了都好了下面就开始吧
| 代码如下 |
复制代码 |
|
//POST提交
function socketPost($url,$data){
$postStr = '';
$postLen = '';
$out = '';
//解析域
$urlInfo = parse_url($url);
$host = $urlInfo['host'];
if(!isset($urlInfo['query'])) $urlInfo['query'] ='';
$path = $urlInfo['path'].'?'.$urlInfo['query'];
//组织数据
foreach($data as $key=>$value){
$postStr .=$key.'='.rawurlencode($value).'&';#这里需要对post的值进行编码，否则会出现中断
}
$postStr = trim($postStr,"&");
$postLen = strlen($postStr);
$fp = fsockopen($host, 80, $errno, $errstr, 3);
if ($fp) {
$out .="POST ".$path." HTTP/1.0＼r＼n";
$out .="Host: ".$host."＼r＼n";
$out .= "Content-type: application/x-www-form-urlencoded＼r＼n";
$out .= "Content-Length: ".$postLen."＼r＼n"; #这里最好加上Connection: close
$out .= "＼r＼n";
$out .= $postStr;
fwrite($fp, $out);
fclose($fp);
}
}

使用方法
| 代码如下 |
复制代码 |
|
socketPost("提交的地址",array("username"=>"这里是post的username","password"=>321312312));
function socketGet($url){
$urlInfo = parse_url($url);
$host = $urlInfo['host'];
if(!isset($urlInfo['query'])) $urlInfo['query'] ='';
$path = $urlInfo['path'].'?'.$urlInfo['query'];
$fp = fsockopen($host, 80, $errno, $errstr, 3);
if ($fp) {
//调用模块进行抓取信息
$out = "GET {$path} / HTTP/1.1＼r＼n";
$out .= "Host: {$host}＼r＼n";
$out .= "Connection: Close＼r＼n＼r＼n";
fwrite($fp, $out);
fclose($fp);
}
}
|
使用方法：socketGet("url");
工作需要封装好方法方便同事调用。
