本文實(shí)例講述了PHP使用Pthread實(shí)現(xiàn)的多線程操作。分享給大家供大家參考，具體如下：
php
html' target='_blank'>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(wú),第一次運(yùn)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(wù)參數(shù)::{$this->param},需要{$nt}秒處理數(shù)據(jù)./n";
$this->res = rand(100, 999);
sleep($nt);
$this->lurl = $this->param;
$this->param = '';
} else {
echo "線程[{$this->name}]等待任務(wù)../n";
}
sleep(1);
}
}
}
//這里創(chuàng)建線程池.
$pool[] = new vote('a');
$pool[] = new vote('b');
$pool[] = new vote('c');
//啟動(dòng)所有線程,使其處于工作狀態(tài)
foreach ($pool as $w) {
$w->start();
}
//派發(fā)任務(wù)給線程
for ($i = 1; $i 10; $i++) {
$worker_content = rand(10, 99);
while (true) {
foreach ($pool as $worker) {
//參數(shù)為空則說(shuō)明線程空閑
if ($worker->param=='') {
$worker->param = $worker_content;
echo "[{$worker->name}]線程空閑,放入?yún)?shù){$worker_content},上次參數(shù)[{$worker->lurl}]結(jié)果[{$worker->res}]./n";
break 2;
}
}
sleep(1);
}
}
echo "所有線程派發(fā)完畢,等待執(zhí)行完成./n";
//等待所有線程運(yùn)行結(jié)束
while (count($pool)) {
//遍歷檢查線程組運(yùn)行結(jié)束
foreach ($pool as $key => $threads) {
if ($worker->param=='') {
echo "[{$threads->name}]線程空閑,上次參數(shù)[{$threads->lurl}]結(jié)果[{$threads->res}]./n";
echo "[{$threads->name}]線程運(yùn)行完成,退出./n";
//設(shè)置結(jié)束標(biāo)志
$threads->runing = false;
unset($pool[$key]);
}
}
echo "等待中.../n";
sleep(1);
}
echo "所有線程執(zhí)行完畢./n";
