php进程 swoole

<?php

$pid = posix_getpid();
$ppid = posix_getppid();
var_dump($pid);
cli_set_process_title("myparent");

for($i = 1;$i<10;$i++){
    $child = new SwooleProcess(function(){
        cli_set_process_title("mychild");
        echo "child ".getmypid().PHP_EOL;
        sleep(10);

    });
    $child->start();
}

while(true){
    sleep(1);
}

如果不进行回收，会产生僵尸进程

[root@localhost swoole]# php test.php 
int(31030)
child 31031
child 31033
child 31034
child 31035
child 31032
child 31036
child 31037
child 31038
child 31039

 子进程输入到父进程

<?php

$pid = posix_getpid();
$ppid = posix_getppid();
var_dump($pid);
cli_set_process_title("myparent");


$child = new SwooleProcess(function(){
    cli_set_process_title("mychild");

    while(true){
        echo "child ".getmypid();
        sleep(1);
    }

},true);

$child->start();

SwooleProcess::wait(false); // true是堵塞式的，读取子进程内容必须放在他前面，才能在被销毁之前拿到数据

//$child1 = new SwooleProcess(function(){
//    cli_set_process_title("mychild1");
//    echo "child1 ".getmypid().PHP_EOL;
//    while(true){
//        sleep(1);
//    }
//
//});
//$child1->start();



while(true){
    echo $child->read()." brady".PHP_EOL;
    sleep(1);
}
