(PHP 4 >= 4.3.0, PHP 5, PHP 7) List all output handlers in use array ob_list_handlers ( void ) Lists all output handlers in use. Returns: This will return an array with the output handlers in use (if any). If output_buffering is enabled or an anonymous function was used with ob_start(), ob_list_handlers() will return "default output handler". Ex

(PHP 4 >= 4.2.0, PHP 5, PHP 7) Return the nesting level of the output buffering mechanism int ob_get_level ( void ) Returns the nesting level of the output buffering mechanism. Returns: Returns the level of nested output buffering handlers or zero if output buffering is not active. See also: ob_start() -

(PHP 4, PHP 5, PHP 7) Turn implicit flush on/off void ob_implicit_flush ([ int $flag = true ] ) ob_implicit_flush() will turn implicit flushing on or off. Implicit flushing will result in a flush operation after every output call, so that explicit calls to flush() will no longer be needed. Parameters: flag TRUE to turn implicit flushing on, FALSE otherwise.

(PHP 4 >= 4.0.4, PHP 5, PHP 7) ob_start callback function to gzip output buffer string ob_gzhandler ( string $buffer, int $mode ) ob_gzhandler() is intended to be used as a callback function for ob_start() to help facilitate sending gz-encoded data to web browsers that support compressed web pages. Before ob_gzhandler() actually sends compressed data, it determines what type of content encoding the browser will accept ("g

(PHP 4 >= 4.2.0, PHP 5, PHP 7) Get status of output buffers array ob_get_status ([ bool $full_status = FALSE ] ) ob_get_status() returns status information on either the top level output buffer or all active output buffer levels if full_status is set to TRUE. Parameters: full_status TRUE to return all active output buffer levels. If FALSE or not set, only the top leve

(PHP 4 >= 4.0.2, PHP 5, PHP 7) Return the length of the output buffer int ob_get_length ( void ) This will return the length of the contents in the output buffer, in bytes. Returns: Returns the length of the output buffer contents, in bytes, or FALSE if no buffering is active. Examples: A simple ob_get_length() example

(PHP 4, PHP 5, PHP 7) Return the contents of the output buffer string ob_get_contents ( void ) Gets the contents of the output buffer without clearing it. Returns: This will return the contents of the output buffer or FALSE, if output buffering isn't active. Examples: A simple ob_get_contents() example <?php ob_start(

(PHP 4 >= 4.3.0, PHP 5, PHP 7) Flush the output buffer, return it as a string and turn off output buffering string ob_get_flush ( void ) ob_get_flush() flushes the output buffer, return it as a string and turns off output buffering. The output buffer must be started by ob_start() with PHP_OUTPUT_HANDLER_FLUSHABLE flag. Otherwise ob_get_flush() will not work. Note: This function is similar to ob_end_flush(), except tha

(PHP 4, PHP 5, PHP 7) Clean (erase) the output buffer and turn off output buffering bool ob_end_clean ( void ) This function discards the contents of the topmost output buffer and turns off this output buffering. If you want to further process the buffer's contents you have to call ob_get_contents() before ob_end_clean() as the buffer contents are discarded when ob_end_clean() is called. The output buffer must be started b

(PHP 4, PHP 5, PHP 7) Flush (send) the output buffer and turn off output buffering bool ob_end_flush ( void ) This function will send the contents of the topmost output buffer (if any) and turn this output buffer off. If you want to further process the buffer's contents you have to call ob_get_contents() before ob_end_flush() as the buffer contents are discarded after ob_end_flush() is called. The output buffer must be sta
