没事的时候自己封装了一个socket类
功能很简单和curl功能是一样的
class socketclass{ private $host; private $url; private $error_no = 0; public $error_str = ''; private $port = 80; private $timeout = 5; private $method; private $param; private $fp; private $content = ''; private $header = array(); public function __construct($host, $port, $url, $param, $method='get', $timeout=5) { $this->host = $host; $this->port = $port; $this->url = $url; $this->timeout = $timeout; $this->method = $method; if(is_array($param)){ $this->param = http_build_query($param); }else{ $this->param = $param; } } private function connect(){ $this->fp = fsockopen($this->host, $this->port, $this->error_no, $this->error_str, $this->timeout); if(!$this->fp){ $this->error_str = 'socket connect failed'; return false; } return true; } private function send(){ $this->fp = ''; if(!$this->connect()){ $this->error_str = 'connect socket failed'; return false; } if($this->method == 'post'){ $header = post $this->url http/1.1\r\n; }else{ if(!empty($this->param)){ $header = get $this->url?$this->param http/1.1\r\n; }else{ $header = get $this->url http/1.1\r\n; } } $header .= content-length: . strlen($this->param) . \r\n; $header .= host:$this->host:$this->port\r\n; $header .= content-type:application/x-www-form-urlencode\r\n; $header .= connection:close\r\n\r\n; if($this->method == 'post'){ $header .= $this->param\r\n\r\n; } if(!empty($this->header)){ foreach ($this->header as $key=>$val){ $header .= $key:$val\r\n; } } fwrite($this->fp, $header); while(!feof($this->fp)){ $this->content .= fread($this->fp, 1024); } fclose($this->fp); return true; } public function getcontent(){ if(!$this->send()){ return false; } $pos = strpos($this->content, \r\n\r\n); $this->content = substr($this->content, $pos); return $this->content; } public function setheader($key, $val){ $this->header[$key] = $val; } public function geterrorstr(){ return $this->error_str; }}$host = 'localhost';$port = 81;$url = 'http://localhost/phpdemo/php/socket_accept.php';$param = array('username'=>'beggar', 'passwd'=>'20060400');$method = 'get';$timeout = 10;$http = new socketclass($host, $port, $url, $param, $method, $timeout);$http->setheader('referer', $url);$http->setheader('accept', '*/*');$header = $http->getcontent();echo $header;
以上就介绍了php socket类，包括了方面的内容，希望对php教程有兴趣的朋友有所帮助。
