我有一个搜索查询,在执行搜索查询后,我将$ result放入一个数组中。
我的PHP代码 -
$contents = $client->search($params); // executing the search
$search = array($contents); // make the result $contents as a array
for ($i = 0; $i < count($search); $i++) {
$search['hits']['total']['title'] = strip_tags($search['hits']['total']['title']); // Trying to access the title
会产生数组----
Array (
[0] => Array (
[took] => 1
[timed_out] =>
[_shards] => Array (
[total] => 2
[successful] => 2
[failed] => 0
)
[hits] => Array (
[total] => 1
[max_score] => 2.6818755
[hits] => Array (
[0] => Array (
[_index] => myindex
[_type] => mytype
[_id] => p36d3742b982586d8d
[_score] => 2.6818755
[_source] => Array (
[title] => Salma Hayek => Salma Hayeks...
[source] => Hello
[guid] => p36d3742b982586d8d
[pub_id] => 54ae51e5
[type] => news
)
)
)
)
)
)
现在问题是我每次尝试访问标题时都会注意到:未定义索引:点击。
我试过像---
$search['hits']['total']['title'] = strip_tags($search['hits']['total']['title']);
$search['']['hits']['total']['title'] = strip_tags($search['']['hits']['total']['title']);
没有什么对我有用,可能是犯了一个简单的错误,任何人都知道我在哪里犯了错误。
我也试过这样使用它----
$search[$i]['hits']['total']['title'] = strip_tags($search[$i]['hits']['total']['title']);
但它给我一个错误,如:
警告:不能将标量值用作数组
如何访问我的标题?
答案 0 :(得分:2)
您遗失$i
,请使用$search[$i]['hits']
。
这是标题为$search[$i]['hits']['hits'][0]['_source']['title']
