(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 >= 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 >= 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 >= 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 >= 4.0.4, 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, 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 >= 4.3.0, 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, PHP 5, PHP 7) Turn on output buffering bool ob_start ([ callable $output_callback = NULL [, int $chunk_size = 0 [, int $flags = PHP_OUTPUT_HANDLER_STDFLAGS ]]] ) This function will turn output buffering on. While output buffering is active no output is sent from the script (other than headers), instead the output is stored in an internal buffer. The contents of this internal buffer may be copied into a string va

(PHP 4 >= 4.3.0, PHP 5, PHP 7) Add URL rewriter values bool output_add_rewrite_var ( string $name, string $value ) This function adds another name/value pair to the URL rewrite mechanism. The name and value will be added to URLs (as GET parameter) and forms (as hidden input fields) the same way as the session ID when transparent URL rewriting is enabled with session.use_trans_sid. Please note that absolute URLs (http://ex

(PHP 4 >= 4.3.0, PHP 5, PHP 7) Reset URL rewriter values bool output_reset_rewrite_vars ( void ) This function resets the URL rewriter and removes all rewrite variables previously set by the output_add_rewrite_var() function or the session mechanism (if session.use_trans_sid was set on session_start()). Returns: Returns TRUE on success or FALSE on failure.
