本篇文章給大家分享的是有關如何在PHP中利用Pthread實現一個多線程,小編覺得挺實用的,因此分享給大家學習,希望大家閱讀完這篇文章后可以有所收獲,話不多說,跟著小編一起來看看吧。
具體如下:
<?php class vote extends Thread { public $res = ''; public $url = array(); public $name = ''; public $runing = false; public $lc = false; public function __construct($name) { $this->res = '暫無,第一次運行.'; $this->param = 0; $this->lurl = 0; $this->name = $name; $this->runing = true; $this->lc = false; } public function run() { while ($this->runing) { if ($this->param != 0) { $nt = rand(1, 10); echo "線程[{$this->name}]收到任務參數::{$this->param},需要{$nt}秒處理數據.\n"; $this->res = rand(100, 999); sleep($nt); $this->lurl = $this->param; $this->param = ''; } else { echo "線程[{$this->name}]等待任務..\n"; } sleep(1); } } } //這里創建線程池. $pool[] = new vote('a'); $pool[] = new vote('b'); $pool[] = new vote('c'); //啟動所有線程,使其處于工作狀態 foreach ($pool as $w) { $w->start(); } //派發任務給線程 for ($i = 1; $i < 10; $i++) { $worker_content = rand(10, 99); while (true) { foreach ($pool as $worker) { //參數為空則說明線程空閑 if ($worker->param=='') { $worker->param = $worker_content; echo "[{$worker->name}]線程空閑,放入參數{$worker_content},上次參數[{$worker->lurl}]結果[{$worker->res}].\n"; break 2; } } sleep(1); } } echo "所有線程派發完畢,等待執行完成.\n"; //等待所有線程運行結束 while (count($pool)) { //遍歷檢查線程組運行結束 foreach ($pool as $key => $threads) { if ($worker->param=='') { echo "[{$threads->name}]線程空閑,上次參數[{$threads->lurl}]結果[{$threads->res}].\n"; echo "[{$threads->name}]線程運行完成,退出.\n"; //設置結束標志 $threads->runing = false; unset($pool[$key]); } } echo "等待中...\n"; sleep(1); } echo "所有線程執行完畢.\n";
以上就是如何在PHP中利用Pthread實現一個多線程,小編相信有部分知識點可能是我們日常工作會見到或用到的。希望你能通過這篇文章學到更多知識。更多詳情敬請關注億速云行業資訊頻道。
