The Output Control functions allow you to control when output is
|
|
sent from the script. This can be useful in several different
|
|
situations, especially if you need to send headers to the browser
|
|
after your script has began outputting data. The Output Control
|
|
functions do not affect headers sent using
|
|
<function>header</function> or <function>setcookie</function>,
|
|
only functions such as <function>echo</function> and data between
|
|
blocks of PHP code.

In the above example, the output from <function>echo</function>
|
|
would be stored in the output buffer until
|
|
<function>ob_end_flush</function> was called. In the mean time,
|
|
the call to <function>setcookie</function> successfully stored a
|
|
cookie without causing an error. (You can not normally send
|
|
headers to the browser after data has already been sent.)

|
|
When upgrading from PHP 4.1 (and 4.2) to 4.3 that due to a bug in
|
|
earlier versions you must ensure that
|
|
<literal>implict_flush</literal> is <literal>OFF</literal> in
|
|
your &php.ini;, otherwise any output with
|
|
<function>ob_start</function> will be not be hidden from output.
