Getting specific element from JSON in PHP

Question

On executing elastic search and storing the result in JSON form

stdClass Object (
 [took] => 119
 [timed_out] => 
 [_shards] => stdClass Object (
 [total] => 5 
 [successful] => 5 
 [failed] => 0 
 )
 [hits] => stdClass Object (
 [total] => 3 
 [max_score] => 1 
 [hits] => Array ( 
 [0] => stdClass Object (
 [_index] => movies 
 [_type] => movie 
 [_id] => 3 
 [_score] => 1 
 [_source] => stdClass Object (
 [title] => The MATRIX 
 [year] => 1975
 )
 )
 [1] => stdClass Object (
 [_index] => movies
 [_type] => movie
 [_id] => 8
 [_score] => 1
 [_source] => stdClass Object (
 [title] => The MATRIX
 [year] => 1975
 )
 )
 [2] => stdClass Object (
 [_index] => movies
 [_type] => movie
 [_id] => 4
 [_score] => 1
 [_source] => stdClass Object (
 [title] => The MATRIX
 [year] => 1975
 )
 )
 )
 )
) 

I want to get value of each movie and year in the above
I tried

foreach($result as $i)
{
 echo $i->title;
 echo $i->year;
}
Notice: Trying to get property of non-object in D:\xampp\htdocs\esearch\index.php on line 16
Notice: Trying to get property of non-object in D:\xampp\htdocs\esearch\index.php on line 17

How to get it?

• fian: Try to convert your json to associative array with passing true on second parameter json_decode($yourjson, true).
• h2ooooooo: The problem isn't the getter, it's the fact that $i isn't an object (seeing how it's 119, then empty, and then an stdClass.
• Akash Kumar: @fian - already done that

Answer 1

You can use following;

foreach($result->hits->hits as $movie)
{
 echo $movie->_source->title;
 echo $movie->_source->year;
}

Answer 2

Try this

 foreach($result->hits->hits as $i)
 {
 echo $i->_source->title;
 echo $i->_source->year;
 }
