# ob_get_clean

(PHP 4 >= 4.3.0, PHP 5)

ob_get_clean -- Get current buffer contents and delete current output buffer

## Description

string ob_get_clean ( void )

This will return the contents of the output buffer and end output buffering. If output buffering isn't active then `FALSE` is returned. ob_get_clean() essentially executes both ob_get_contents() and ob_end_clean().

範例 1. A simple ob_get_clean() example

`<?php ob_start(); echo "Hello World"; $out = ob_get_clean(); $out = strtolower($out); var_dump($out); ?>`

Our example will output:

    string(11) "hello world"
