PHP ob_implicit_flush() Function

Example

Send content immediately to the browser on every statement which produces output:

<?php
// Turn on implicit flushing
ob_implicit_flush(1);

// Some browsers will not display the content if it is too short
// We use str_pad() to make the output long enough
echo str_pad("Hello World!", 4096);

// Even though the script is still running, the browser already can see the content
sleep(3);
?>

Definition and Usage

The ob_implicit_flush() function enables or disabled implicit flushing. When enabled, implicit flushing sends output directly to the browser as soon as it is produced so that calls to the flush() function are not needed.

Syntax

ob_implicit_flush(flag);

Parameter Values

Parameter	Description
