Example #1 Output Control example
<?php
ob_start
();
echo "Hello\n";
setcookie("cookiename", "cookiedata");
ob_end_flush();
?>In the above example, the output from echo would be stored in the output buffer
until ob_end_flush() was called. In the mean
time, the call to setcookie()
successfully stored a cookie without causing an error. (Headers
