调用ob_end_flush()网页仍旧不能显示问题?
写了一个简单的demo,理论上调用ob_end_flush()后,浏览器端应该马上显示网页,但是结果却是整个php文件运行完成才刷新出来,如下代码
- PHP code
<?php @ob_start(); include 'test.tpl.php'; @ob_end_flush(); sleep(3); //--------------------------------------------------------------------- // invoke client js $s = sprintf(" <script>%s.%s();</script>", 'oCar', 'updateDiv1'); // output the buffer to client echo $s; unset($s); @flush(); //---------------------------------------------------------------------- sleep(3); // invoke client js $s = sprintf(" <script>%s.%s();</script>", 'oCar', 'updateDiv2'); // output the buffer to client echo $s; unset($s); @flush();
------解决方案--------------------------------------------------------
试试改下php.ini对于输出的设置
output_buffering = Off // 如果设置为On ,那么默认会先缓存4096B的输出内容
implicit_flush = On // I don't know...

浏览器缓存
例子1:
<?PHP $number = 0; for ($i = 0; $i < 10; $i++) { echo $number++; // echo "ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd".'<br>'; ob_flush(); flush(); sleep(1); } ?>
implicit_flush = Off修改为implicit_flush = On了。
然后上面的例子有时候可以输出有时候又不能。
