for ($i=0; $i        ob_start();   
        echo "This is iteration $i: ";   
        // * Dont do this!   
        // $buf = ob_get_contents();   
        // ob_clean();   
        // * Use this instead:   
        $buf = ob_get_flush();   
        //缓冲区关闭,竟然还有内容   
        $test=ob_get_contents();   
        echo $test,---->;   
        echo $buf;   
        echo memory_get_usage()." ";   
        echo
;   
}   
?>   

for ($i=0; $i        ob_start();
        echo "This is iteration $i: ";
        // * Dont do this!
        // $buf = ob_get_contents();
        // ob_clean();
        // * Use this instead:
        $buf = ob_get_flush();
        //缓冲区关闭,竟然还有内容
        $test=ob_get_contents();
        echo $test,---->;
        echo $buf;
        echo memory_get_usage()."";
        echo
;
}
?>

ob_get_flush相当于ob_end_flush,只有一点区别,ob_get_flush获取缓存区内容,保存到变量中,并关闭缓存区。
