ob_get_clean - Get current buffer contents and delete current output buffer

SYNOPSIS

       string ob_get_clean (void  )

DESCRIPTION

	Gets the current buffer contents and delete current output buffer.

       ob_get_clean(3) essentially executes both ob_get_contents(3) and ob_end_clean(3).

	The output buffer must be started by ob_start(3) with PHP_OUTPUT_HANDLER_CLEANABLE flag. Otherwise ob_get_clean(3) will not work.

RETURN VALUES

	Returns the contents of the output buffer and end output buffering. If output buffering isn't active then FALSE is returned.

EXAMPLES

       Example #1

	      A simple ob_get_clean(3) example

	      <?php

	      ob_start();

	      echo "Hello World";

	      $out = ob_get_clean();
	      $out = strtolower($out);

	      var_dump($out);
	      ?>

	      The above example will output:

	      string(11) "hello world"

OB_GET_FLUSH(3) 							 1							   OB_GET_FLUSH(3)

ob_get_flush - Flush the output buffer, return it as a string and turn off output buffering

SYNOPSIS

       string ob_get_flush (void  )

DESCRIPTION

       ob_get_flush(3) flushes the output buffer, return it as a string and turns off output buffering.

	The output buffer must be started by ob_start(3) with PHP_OUTPUT_HANDLER_FLUSHABLE flag. Otherwise ob_get_flush(3) will not work.

       Note

	       This function is similar to ob_end_flush(3), except that this function returns the buffer as a string.

RETURN VALUES

	Returns the output buffer or FALSE if no buffering is active.

EXAMPLES

       Example #1

	      ob_get_flush(3) example

	      <?php
	      //using output_buffering=On
	      print_r(ob_list_handlers());

	      //save buffer in a file
	      $buffer = ob_get_flush();
	      file_put_contents('buffer.txt', $buffer);

	      print_r(ob_list_handlers());
	      ?>

	      The above example will output:

	      Array
	      (
		  [0] => default output handler
	      )
	      Array
	      (
	      )
