哥么们，yii2.0命令行应用，我怎么立即输出内容到终端上啊， [ 2.0 版本 ]

it works for me:

class HskcmdController extends \yii\console\Controller
{
    public function actionWords() {
        $this->stdout("Pre-process for hsk1to6_words:\n", Console::BOLD, Console::FG_BLUE);

how about you try this?

<?php
    ob_clean();
    while(true){
        echo str_repeat(' ',1024*1024*4);
        echo 'hello, world ...<br />';
        ob_flush();
        flush();
        usleep(1000);
    }
