Question

Here is example of code I’m expecting to print message each second.

set_time_limit(0);

foreach($array as $key => $value)
{
    echo $value;

    sleep(1);
}

I’m wondering is it possible to output results during each step in loop instantly, without waiting until it stops.

Answer 1

yes.
you can do it using php’s flush mechanism.

for example:

   <?
    ob_implicit_flush(true);
    foreach($array as $key => $value)
{
    echo $value;

    sleep(1);
}
    ?>
