【www.gdgbn.com--php函数】

用法
http_build_query($formdata[,string $numeric_prefix[,string $arg_spearotor]])

http_build_query函数是php教程5加入的，作用就是把数组或对象转换成url的querystring

*/
$data=array(
"foo"=>"bar",
"baz"=>"boom",
"cow"=>"milk",
"php"=>"hypertext processor"
);             //定义数组
echo http_build_query($data);        //使用函数操作数组
echo "

";
$data=array("foo","bar","baz","boom","cow" =>"milk","php"=>"hypertext processor");
echo http_build_query($data);        //使用函数操作数组
echo "

";
echo http_build_query($data,"myvar_");      //使用第二个参数
echo "

";
class myclass           //定义类
{
  var $foo;           //为类添加属性
  var $baz;           //添加属性
  function myclass()          //为类添加方法
  {
    $this->foo="bar";
    $this->baz="boom";
  }
}
$data=new myclass();         //为类初始化对象
echo http_build_query($data);        //使用函数操作对象
?>
