PHP flush() 函数
实例
在脚本完成运行之前向浏览器输出一个字符串：
<?php
// Some browsers will not display the content if it is too short
// We use str_pad() to make the output long enough
echo str_pad("Hello World!", 4096);
// Use flush() to send the string to the browser
flush();
// Display the rest of the content three seconds later
sleep(3);
echo "<br>";
echo "Hello World!";
?>
亲自试一试 »
// Some browsers will not display the content if it is too short
// We use str_pad() to make the output long enough

// Use flush() to send the string to the browser
flush();
// Display the rest of the content three seconds later
sleep(3);
echo "<br>";
echo "Hello World!";
?>
