php读取ini配置文件属性

ini的内容格式如下,请根据自己的INI,格式修改下段程序.
autostart = false
font_size = 12
font_color = red
===================
function get_ini_file($file_name = "demo.ini"){
 $str=file_get_contents($file_name);//读取ini文件存到一个字符串中.
 $ini_list = explode("
",$str);//按换行拆开,放到数组中.
 $ini_items = array();
 foreach($ini_list as $item){
  $one_item = explode("=",$item);
  if(isset($one_item[0])&&isset($one_item[1])) $ini_items[trim($one_item[0])] = trim($one_item[1]); //存成key=>value的形式.
 }
 return $ini_items;
}

function get_ini_item($ini_items = null,$item_name = ''){//获得INI条目的值.
         if(empty($ini_items)) return "";
   else return $ini_items[$item_name];
}

$ini_items = get_ini_file("demo.ini");

echo get_ini_item($ini_items,'font_size'); //输出获得的值.
