flush

(PHP3 , PHP4 )

flush -- Flush the output buffer

Description

void flush(void);

Flushes the output buffers of PHP and whatever backend PHP is using (CGI, a web server, etc.) This effectively tries to push all the output so far to the user's browser.

I have noticed that this doesn't force IE to display the page(or what is loaded so far), but it does in netscape.

On my system using PHP3 flush is working with netscape AND IE but only when you use print("something"); instead of echo "";

Flush example:


$i = 1;

for($i; $i < 10; $i++){

print"$i
";//($i-break tag)

flush();

sleep(1);

}



On my NS the above example doesn't work without the break tag. Interesting.

A quick hack, is to do System("echo 'hello world'); flush;

I get flush() to work well with IE5 when I close all of the tables, forms and frames. i.e.

<table><? flush(); ?></table>


won't work, use


<table></table><? flush(); ?>

instead.

Change the above example to:


$i = 1;

for($i; $i < 10; $i++){

print"$i

";

flush();

sleep(1);

}



i.e. paragraphs instead of line breaks.
Works in my IE5 (5.00.2314.1003).

Some sample code:


<HTML>

<BODY>

Welkom to chat room:

<?

flush();

while(10==10) // cool while loop

{

// get here som lines from a dbase or so

// and put in in $tekst



print($tekst);

flush();

}
