睡眠前PHP输出文本 [英] PHP output text before sleep

问题描述

我希望PHP输出一些文本，然后睡一秒钟半，然后再输出一些文本.

I want PHP to output some text, then sleep for a second and a half, and then output some more text.

<?php

echo 'Output one.';

usleep(1500000);

echo 'Output two.';

?>

我的问题是所有文本同时显示-等待了1.5秒后 .我已经阅读了有关称为flush的函数的内容-但它似乎不起作用.也许我没有用它写.任何帮助，将不胜感激^^

My problem is that all text is being put out simultaneously - after having waited those 1.5 seconds. I have read something about a function called flush - but it doesn't seem to work. Maybe I'm not using it write. Any help would be appreciated ^^

提前谢谢！

推荐答案

检查一下

<?php

ob_start();

echo 'Output one.';
ob_flush();
usleep(1500000);
echo 'Output two.';
ob_flush();

?>
