How to push items into array in php - php

Question

I am using Laravel with ES and trying to build a dynamic query.
But the following doesnt work:
$query[] = ['term' => ['city' => 1]];
$query[] = ['term' => ['state' => 2]];
$query[] = ['range' => ['price' => ['lte' => 2]]];
$asd = ['filtered' => [
'query' => [
'match' => ['title' => Input::get('query')]
],
'filter'=> [
'bool' => [
'must' => [
['term' => [ 'is_active' => 1] ],
[ 'range' => [
'end_date' => [
'from' => 'now'
]
]
],
$query
]
]
],
],];
echo json_encode($asd);
This will append $query[] wrong into $asd, like:
{"term":{"is_active":1}},
{"range":{"end_date":{"from":"now"}}},
[
{"term":{"city":1}},
{"term":{"state":2}},
{"range":{"price":{"lte":2}}}
]
How I would like to append it is:
{"term":{"is_active":1}},
{"range":{"end_date":{"from":"now"}}},
{"term":{"city":1}},
{"term":{"state":2}},
{"range":{"price":{"lte":2}}}
without the [] around it.
Solved:
$asd = ['filtered' => [
'query' => [
'match' => ['title' => Input::get('query')]
],
'filter'=> [
'bool' => [
'must' =>
$query
]
],
],];

A valid json string always consist of a single object or an array of objects.
The string you are asking for is not legal json, it would not be possible to parse.
Json with a single object looks like this:
{ // Object start.
"property": "value" // Where value could be a object or array or whatever.
} // Object end.
And if an array:
[ // Array start.
"Array value" // which could be an object or another array or whatever.
] // Array end.
When you convert your PHP array containing associative arrays, it will be converted into a string containing a array of objects.
You could always remove the [] from the string if you wish it to look like you described, but it will not be valid json.
Edit:
An elastic query looks basically like this:
{
"query": {
"term": { data ... }
}
}
I'm guessing that what you want/need to do is to create the php array like this:
$query = [
'query' => [
'term' => [
'state' => 2
'city' => 1
],
'range' => [
'price' => [
'lte' => 2
]
]
]
]
Which would result in a JSON string that looks like this:
{
"query":
{
"term":
{
"state": 2,
"city": 1
},
"range":
{
"lte": 2
}
}
}
