Parsing object with arrays in PHP - php

Question

I'm using Google's Natural Language API and it's working fine and returning data. I'm just not able to parse it correctly. I'd like to form a JSON object I can then use with AJAX or similar. What I need out of this are mainly the sentences and their sentiment. I'm struggling with this object that I get back:
object(Google\Cloud\NaturalLanguage\Annotation)#21 (1) {
["info":"Google\Cloud\NaturalLanguage\Annotation":private]=>
array(3) {
["documentSentiment"]=>
array(2) {
["magnitude"]=>
float(1.4)
["score"]=>
int(0)
}
["language"]=>
string(2) "en"
["sentences"]=>
array(2) {
[0]=>
array(2) {
["text"]=>
array(2) {
["content"]=>
string(19) "I love everything!\"
["beginOffset"]=>
int(0)
}
["sentiment"]=>
array(2) {
["magnitude"]=>
float(0.8)
["score"]=>
float(0.8)
}
}
[1]=>
array(2) {
["text"]=>
array(2) {
["content"]=>
string(18) "I hate everything!"
["beginOffset"]=>
int(21)
}
["sentiment"]=>
array(2) {
["magnitude"]=>
float(0.6)
["score"]=>
float(-0.6)
}
}
}
}
}
ADDED:
The very last bit of my PHP code is:
$annotation = $language->analyzeSentiment($text);
$sentiment = $annotation->sentiment();
echo 'Text: ' . $text . '
Sentiment: ' . $sentiment['score'] . ', ' . $sentiment['magnitude'];
return $sentiment;
This successfully returns the score and magnitude for the overall "document" as shown in the part of the array under "documentSentiment". What I need (in addition to this), is the data under sentences. In particular, content, magnitude and score.

Answer 1

Since $sentiment['sentences'] is an array -
["sentences"]=>
array(2) {
...
}
you need to loop over the values, with foreach() for example -
....
echo 'Text: ' . $text . '
Sentiment: ' . $sentiment['score'] . ', ' . $sentiment['magnitude'];
foreach($sentiment['sentences'] as $sentence){
echo 'Text: ' .$sentence["text"]["content"] . '
Sentiment: ' . $sentence["sentiment"]["score"] . ', ' . $sentence["sentiment"]["magnitude"];
}
