Extracting triples from text in php using Stanford-NLP? - php

Question

I have a text .. I went to extract triples from text .. I use Stanford-NLP Library in php Standford-NLP How can I extract triples(subject - object - predicate)?
The example code in the GitHub ReadMe shows how to write the code. The output is a list of word/part-of-speech pairs. Looking at the first example,
"What does the fox say?" becomes:
array(3) {
["wordsAndTags"]=>
array(6) {
[0]=>
array(2) {
[0]=>
string(4) "What"
[1]=>
string(2) "WP"
}
[1]=>
array(2) {
[0]=>
string(4) "does"
[1]=>
string(3) "VBZ"
}
[2]=>
array(2) {
[0]=>
string(3) "the"
[1]=>
string(2) "DT"
}
[3]=>
array(2) {
[0]=>
string(3) "fox"
[1]=>
string(2) "NN"
}
[4]=>
array(2) {
[0]=>
string(3) "say"
[1]=>
string(2) "VB"
}
[5]=>
array(2) {
[0]=>
string(1) "?"
[1]=>
string(1) "."
}
}
["penn"]=>
array(2) {

}

array(2) {

}
}
}
}
["typedDependencies"]=>
array(5) {

array(2) {

}
[1]=>
array(2) {

[1]=>
array(2) {

[4]=>
array(3) {

[1]=>

}
}
Then I need to extract triples .. How can I do that?
