纠结了好久,也不行,
b.php的代码
/**<br /> *Run<br /> *多线程机制<br /> */<br /> function run($i){<br /> //连接服务器:注意如果你是以ssl/tls连接时,$host的值为:“ssl://www.example.com”即应加上"ssl://"前缀。<br /> //且$port值为443<br /> $host = $_SERVER['HTTP_HOST'];<br /> $port = 80;<br /> $fp = fsockopen($host,$port,$errorno,$errormsg); //连接服务器 <br /> if(!$fp){<br /> die("$errorno----------$errormsg");<br /> }else{<br /> <br /> $i = "i=$i";//传递的数据<br /> $path = '/a.php';//请求路径<br /> $method = 'POST'; //请求方法(POST方式)<br /> <br /> //HTTP的请求一般是GET或POST命令(POST用于FORM参数的传递)。格式为:方法 路径/文件名 HTTP/1.1/r/n(协议版本)<br /> $post = "$method $path HTTP/1.1/r/n"; <br /> //GET方式为:"GET /test/create_file.php?i HTTP/1.1/r/n";<br /> <br /> //Host头域指定请求资源的Intenet主机和端口号,必须表示请求url的原始服务器或网关的位置。HTTP/1.1请求必须包含主机头域,否则系统会以400状态码返回。<br /> $post .= "HOST: {$_SERVER['HTTP_HOST']} /r/n";<br /> <br /> //Content-Type实体头用于向接收方指示实体的介质类型,指定HEAD方法送到接收方的实体介质类型,或GET方法发送的请求介质类型。<br /> $post .= "Content-type: application/x-www-form-urlencoded/r/n";<br /> <br /> //Content-length它指示HTTP体信息的长度(字节)。<br /> $post .= "Content-length: ".strlen($i)."/r/n";<br /> <br /> $post .= "Connection: Close/r/n/r/n";<br /> <br /> $post .= "$i/r/n";//POST方式传递数据,在GET方式时,此处不要。<br /> fputs($fp,$post);<br /> }<br /> fclose($fp);<br /> }<br /> <br /> //触发多线程 <br /> for($i=0;$i<=2;$i++){<br /> run($i); <br /> }

刚刚学习php 呵呵

function conWrite($filename, $content) <br /> { <br /> $filename_lock = $filename.'.lock'; <br /> while(1) { <br /> if(file_exists($filename_lock)) { <br /> usleep(1000); <br /> } else { <br /> touch($filename_lock);//加锁 <br /> $f = fopen($filename, 'w'); <br /> fwrite($f,$content); <br /> fclose($f); <br /> unlink($filename_lock); <br /> break; <br /> } <br /> } <br /> if(file_exists($filename_lock)) { <br /> unlink($filename_lock); <br /> } <br /> }
------解决方案--------------------
个人采集经验,一直以来都是多线程就死机。。。感觉PHP对多线程的支持不太友好
------解决方案--------------------
php本身就不支持多线程
