swoole_process模拟耗时操作

Posted 2021-12-28 saintdingspage

• 一例串行阻塞操作

<?php
$start = time();
$tasklists = [
    ‘/root/文档/longtale1.txt‘,
    ‘/root/文档/longtale2.txt‘,
    ‘/root/文档/longtale3.txt‘,
    ‘/root/文档/longtale4.txt‘,
    ‘/root/文档/longtale5.txt‘,
];

function parseurl($path)

    sleep(2);  #模拟某些耗时操作
    return "这个文件的文件名是".$path."\n";


foreach ($tasklists as $tasklist)

    echo parseurl($tasklist);

$end = time();
echo "共耗时:".($end-$start);

• 异步操作

<?php
    $start = time();

    $tasklists = [
    ‘/root/文档/longtale1.txt‘,
    ‘/root/文档/longtale2.txt‘,
    ‘/root/文档/longtale3.txt‘,
    ‘/root/文档/longtale4.txt‘,
    ‘/root/文档/longtale5.txt‘,
    ];

    $processlist=[];

    function parseurl($path)
    
        sleep(2);
        return "要解析的文件名为".$path.PHP_EOL;
    

    foreach($tasklists as $tasklist)
    
        $process = new swoole_process(function(swoole_process $sw) use($tasklist)
            $ret = parseurl($tasklist);
            $sw->write($ret);
            ,false);
        $process->start();
        array_push($processlist,$process);
    

    foreach($processlist as $myprocess)
    
        echo  $myprocess->read().PHP_EOL;
    

    $end = time();
    echo "总共耗时".($end-$start);
?>
