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

坑爹的可以了, 要把 / 换成 \
来个人接一下分!!!
刚刚学习php 呵呵
function conWrite($filename, $content) { $filename_lock = $filename.'.lock'; while(1) { if(file_exists($filename_lock)) { usleep(1000); } else { touch($filename_lock);//加锁 $f = fopen($filename, 'w'); fwrite($f,$content); fclose($f); unlink($filename_lock); break; } } if(file_exists($filename_lock)) { unlink($filename_lock); } }
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
php本身就不支持多线程
坑爹的可以了, 要把 / 换成 \
a.php 代码是什么用?
