Question

我从表中提取反馈并通过将其转换为以下格式进行分析：

字符串：食物非常糟糕

显性：否定，分数：Array ( [neg] => 0.5 [neu] => 0.25 [pos] => 0.25 )

字符串：车很糟糕

显性：否定，分数：Array ( [neg] => 0.5 [neu] => 0.25 [pos] => 0.25 )

字符串：桥梁非常糟糕

显性：否定，分数：Array ( [neg] => 0.5 [neu] => 0.25 [pos] => 0.25 )

我想做的就是计算所有负值，正值和中性值，并将它们显示在饼图中

这是我想要使用数组元素

开发的图表示例

你可以这样做： -

<?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
?>
