You can enable output buffering for all files by setting this directive
|
|
to 'On'. If you wish to limit the size of the buffer to a certain size -
|
|
you can use a maximum number of bytes instead of 'On', as a value for
|
|
this directive (e.g., output_buffering=4096).
|
|
This directive is always Off in PHP-CLI.

|
|
You can redirect all of the output of your scripts to a function. For
|
|
example, if you set output_handler to
|
|
<function>mb_output_handler</function>, character encoding will be
|
|
transparently converted to the specified encoding. Setting any output
|
|
handler automatically turns on output buffering.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
You cannot use both <function>mb_output_handler</function> with
|
|
<function>ob_iconv_handler</function> and you cannot use both

<function>ob_gzhandler</function> and
|
|
<link linkend="ini.zlib.output-compression">zlib.output_compression</link>.

&false; by default. Changing this to &true; tells PHP to tell the
|
|
output layer to flush itself automatically after every output block.
|
|
This is equivalent to calling the PHP function
|
|
<function>flush</function> after each and every call to
|
|
<function>print</function> or <function>echo</function> and each and
|
|
every <literal>HTML</literal> block.

When using PHP within an web environment, turning
|
|
this option on has serious performance implications and is generally
|
|
recommended for debugging purposes only. This value defaults to
|
|
&true; when operating under the <literal>CLI SAPI</literal>.
