我是一名中级PHP程序员,但我正在努力使用Google AJAX API的输出.我有以下转换为stdClass
stdClass Object (
[responseData] => stdClass Object (
[results] => Array (
[0] => stdClass Object (
[GsearchResultClass] => GwebSearch

[cursor] => stdClass Object (
[pages] => Array (
[0] => stdClass Object ( [start] => 0 [label] => 1 )
[1] => stdClass Object ( [start] => 4 [label] => 2 )
[2] => stdClass Object ( [start] => 8 [label] => 3 )
[3] => stdClass Object ( [start] => 12 [label] => 4 )
[4] => stdClass Object ( [start] => 16 [label] => 5 )
[5] => stdClass Object ( [start] => 20 [label] => 6 )
[6] => stdClass Object ( [start] => 24 [label] => 7 )
[7] => stdClass Object ( [start] => 28 [label] => 8 )
)
[estimatedResultCount] => 4370000
[currentPageIndex] => 0
[moreResultsUrl] => http://www.google.com/search?oe=utf8&ie=utf8&source=uds&start=0&hl=en&q=antique+shoes
)
)
[responseDetails] =>
[responseStatus] => 200
)
我需要的只是输出[estimatedResultCount]的数字(4370000),但无论我尝试多少种不同的方式,我都无法正确解析它.
解决方法:
$obj->responseData->cursor->estimatedResultCount
