使用PHP如何每隔一定时间回显内容? [英] Using PHP how to echo content every certain amount of time?

问题描述

代码:

echo "1";
sleep(1);

echo "2";
sleep(1);

echo "3";

正在尝试做的是让脚本在屏幕上回显"1"，然后等待一秒钟，然后显示"2"，以此类推...脚本等待2秒钟，然后一次显示所有内容.我只知道这与缓冲有关

What am trying to do is have the script echo "1" in the screen wait for one second then display "2" etc... As is the script waits for 2 seconds then displays all content at one. All i know about this is that it has do to with buffering

推荐答案

在脚本开始处通过刷新禁用输出缓冲，并激活隐式输出缓冲区刷新.这应该做到:

Disable output buffering by flushing at the beginning of script, and activate implicit output buffer flushing. This should do it:

ob_implicit_flush(true);
ob_end_flush();

for ($i=0; $i<5; $i++) {
   echo $i.'<br>';
   sleep(1);
}
