本文介绍下,在php中有关多线程编程之管道通信的例子,有需要的朋友参考下。
php多线程实现管道通信,代码如下: fifoPath = $fifoPath; } // 写管道函数开始 function open_write() { $this->w_pipe = fopen($this->fifoPath, 'w'); if ($this->w_pipe == NULL) { error("open pipe {$this->fifoPath} for write error."); return false; } return true; } function write($data) { return fwrite($this->w_pipe, $data); } function write_all($data) { $w_pipe = fopen($this->fifoPath, 'w'); fwrite($w_pipe, $data); fclose($w_pipe); } function close_write() { return fclose($this->w_pipe); } /// 读管道相关函数开始 function open_read() { $this->r_pipe = fopen($this->fifoPath, 'r'); if ($this->r_pipe == NULL) { error("open pipe {$this->fifoPath} for read error."); return false; } return true; } function read($byte = 1024) { return fread($this->r_pipe, $byte); } function read_all() { $r_pipe = fopen($this->fifoPath, 'r'); $data = ''; while (!feof($r_pipe)) { //echo "read one K\n"; $data .= fread($r_pipe, 1024); } fclose($r_pipe); return $data; } function close_read() { return fclose($this->r_pipe); } /** * 删除管道 * * @return boolean is success */ function rm_pipe() { return unlink($this->fifoPath); } } /* 此类实现简单的管道通信*/ ?> 有关php中多线程的实现方法,请参考如下文章: 理解 php 多线程的妙用 php 多线程抓取网页的代码分享 php多线程(不使用fork)实例分享 php多线程类的代码分享 php支持多线程下载的例子 |
