when to use ob_start() and ob_flush example only.

[redarrow]

<?php session_start();
function add_shopping($price,$quienty,$shipping,$discount,$tax,$payments){
$total=($price*$quienty)+($shipping)-($discount);
$taxrate=($tax/100)+1;
$total=$total*$taxrate;
$monthly=$total/$payments;
$_SESSION['monthly']=$monthly;
$_SESSION['total']=$total;
$_SESSION['payments']=$payments;
return;
}
echo add_shopping('20.00','10','7.50','10%','17.50','12');
echo "Complete total ".£.number_format($_SESSION['total'],2)."\n
<br> <br> ".$_SESSION['payments']." monthly payments ".£.number_format($_SESSION['monthly'],2)."<br>";
ob_start();
echo "<br> ".$_SESSION['payments']='52'." weekly payments ".£.number_format($_SESSION['monthly']/4,2)." ";
ob_flush();
?>

 

Your all notice there the php function ob_start used on this page, and might wonder why, also there ob_flush() used at the end of the page.

 

grate stuff i say....

 

i reset the session so there no conflict to 52 without ob_start() and ob_flash never do that it change all numbers and give wrong result.

I use output buffering for exceptions everywhere.  It enables me to easily log trace and object information.

What does it change the numbers too? What result does it give?

 

You have a syntax error on the last two echo statements, a pound sign not wrapped in quotes.

 

Is English your primary language?
