-Flush current output to the browser
-====Description====
-<well size="sm"><html><span style="font-size:125%;"></html>[[flush]] ( )
-</well>
-This function will send out any pending buffered data immediately
-====Parameters====
-None
-====Return Value====
-None
-====Example====
-<code php>
-<?
-print("This data will be buffered for a while...");
-flush();
-print("Buffering will start again here...");
-?>
-</code>
-====Note====
-This function attempts to push current output all the way to the browser with a few caveats:
-  * [[flush()]] has no effect on any client-side buffering in the browser
-  * Results vary by browser: different browsers have different requirements for displaying anything before the end of the script or page
-  * To overcome these browser buffering issues and obtain immediate display, you may have to send a minimum amount of data, an end-of-line (EOL) character or an html tag
-  * See http://php.net/manual/en/function.flush.php for more insight into differences between browsers and the use of [[flush()]]
