foreach output display, progress related issues, expert solution

foreach output display, progress issues, help the expert to solve.

$citycode = Array ("Beijing" = "101010100",
"Qingxia County" = "101090702",
"Ci" = "101091007",
"Chiayi" = "101340901",
"Alishan" = "101340902",
"Yushan" = "101340903",
"Newport" = "101340904"
);
foreach ($citycode as $key = = $value) {

echo ' output '. $value. '
';

}
?>


I'm going to output an array, but the array can be very much (I'm going to do some work with the array), I want the array to be a single bar, or 5 5 bars to show slowly. Because this is not the case, I have to wait a long time to see the results of execution, not see the progress of execution.

Add the following statement to the front
Ob_start (); Open output Buffers
Ob_end_flush ();
Ob_implicit_flush (1); Immediate output
You can output your output immediately.
