从Array值获取值以形成聊天

I'm pulling feedback from a table and analyzing it by converting it to the format below:

String: The food is very bad

Dominant: neg, scores: Array ( [neg] => 0.5 [neu] => 0.25 [pos] => 0.25 )

String: The car is very bad

Dominant: neg, scores: Array ( [neg] => 0.5 [neu] => 0.25 [pos] => 0.25 )

String: The bridge is very bad

Dominant: neg, scores: Array ( [neg] => 0.5 [neu] => 0.25 [pos] => 0.25 )

All I want to do is to compute all the values for negative, positive and neutral and present them in a pie chart

This is an example of the chart I want to develop using the array element

enter image description here

    You can do it like below:-

    <?php
$a = Array ( 'neg' => 0.5, 'neu' => 0.25, 'pos' => 0.25 );
$key = array_keys($a); //get te keys of the array
$b = Array ( 'neg' => 0.5, 'neu' => 0.25, 'pos' => 0.25 );
$c=  Array ( 'neg' => 0.5, 'neu' => 0.25, 'pos' => 0.25 );
$d = array_map(function () {
    return (array_sum(func_get_args())/3)*100; // add all three array corresponding keys values and convert them to percentage
}, $a, $b,$c);

$d = array_combine($key,$d); // now combine key array and sum array
$d = array('Sentiment'=>'rating') + $d; // add which type of chart it is as a key value pair
$rating_data = array(); //create a new array variable

foreach($d as $key=>$val){
    $rating_data[] = array($key,$val); //convert summ array to key,value sub-array and assig it to new array
}
 $encoded_data = json_encode($rating_data); //json encode the new array
?>
