最近......
我的VPS有一个自动更新，这搞砸了我的PHP脚本上次运行的方式。上次，我甚至不需要使用ob_flush或任何输出缓冲相关的解决方案来在脚本完成之前查看我的输出。它只是简单地工作。
这是自动软件更新：

所以我去了我的PHP ini并检查我的值是否改变了，我相信他们做了，所以我改变了我的max_exec时间，内存限制，output_buffering关闭等等。脚本仍然等待所有事情在它之前完成输出什么。所以我决定在我的脚本中开始使用flush。我启动了一个测试脚本并编写了以下内容：
<?php
header( 'Content-type: text/html; charset=utf-8' );
ini_set('max_execution_time' ,0);
ini_set('set_memory_limit', -1);
ini_set('output_buffering', 'Off');
set_time_limit(0);
while (ob_get_level()) ob_end_clean();
ob_end_clean();
ob_implicit_flush();
ob_end_flush();
ob_end_clean();
echo 'Hello';
ob_flush();
flush();
sleep(5);
echo 'World!';
ob_flush();
flush();
?>
我使用书中的每个解决方案来尝试修复它并猜猜是什么......？ 它仍然等待5秒才能说出Hello World而不是说Hello，等待5秒然后输出世界。
PHP版本：5.6.30
我喜欢通过浏览器访问我的PHP脚本，但我可能会被迫使用CLI，因为它不起作用。
该死的，我只是将我的PHP.ini文件粘贴到任何PHP技术向导中，可能会找到一个问题。
