求教一个关于对象数组的问题
本人刚学php，有个小问题不知道怎么解决。

我有一个数组，数组里的内容如下：

PHP code

<!--Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->Array ( [0] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => 1 ) [1] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => 1333353649:1 )[2] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => flash )[3] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecbd5f8c4dbe )[4] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => http://www.baidu.com ) [5] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecbd6154b2a7 ) [6] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => 这是一个地址文件 ) [7] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecbd9d8b1b04 ) [8] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => 010-100000 ) [9] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecbd9ed176ed ) [10] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => http://www.Google.com ) [11] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecbda0cc2f65 ) [12] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => 什么都没有 ) [13] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecbda2cce3cf ) [14] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => 汉语 ) [15] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecbdad643aa0 ) [16] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => FM ) [17] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecbdbc2bbc73 ) [18] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => 999.8 ) [19] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecbdbd8600a5 ) [20] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => 200000000 ) [21] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecbdc0b38fe2 ) [22] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => 90 ) [23] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => ) [24] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecc8cb6be29c ) [25] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => ) [26] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => field_4ecc97529e9f4 ) [27] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => 176 ) )  

这里面的 title基本都是一样的。我如何取出meta_value里的每一项值呢？

求高人指点

如果是：
$arr = 
Array ( 
[0] => stdClass Object ( [post_title] => 测试标题基本一样啊 [meta_value] => array(123,'abc',['param']=>'param_value') ) 
)

$abc = $arr->meta_value[1];
$param = $arr->meta_value['param'];
