PHP uses flush() ob_flush() to output strings one by one_PHP tutorial

In the past, js was used to instantiate chat rooms or non-refresh output. In fact, php can be implemented separately. In php, we can use flush() ob_flush().

ob_end_clean(); //Clear the output cache and close the cache
echo str_pad(' ',256);//Output 256 bytes of space (under the IE browser, more than 256 bytes must be accepted before the output is displayed
)

echo '
abc___'.$i;

The code is as follows

代码如下	复制代码
for($i=0;$i<5;$i++){ echo ' abc___'.$i; flush(); ob_flush(); sleep(1); }

Copy code

for($i=0;$i< 5;$i++){

flush(); ob_flush();

sleep(1);

} This method is not available under Opera because the Opera browser does not output content before encountering an html tag
