ob_flush 需要很长时间才能执行

In my website(running with drupal) the ob_flush function takes a long time(between 10 - 100 secs) to be executed. How do I find out why? What can cause this so long time?

推荐答案

试试这个:

ob_start();
//Your code to generate the output
$result = ob_get_contents(); //save the contents of output buffer to a string
ob_end_clean();
echo $result;

对我来说它运行得很快.
