Question

<?php
$i = 1; 
$query = mysqli_query($conn, 'SELECT fback FROM whatyouthink');

$featured = array();
$count = 1;
while($a = mysqli_fetch_array($query)) {   
     $featured[$count] = $a[0];
     $count++; 
}


//I'm passing all the selected records to another script to reformat

require_once __DIR__ . '/../autoload.php';
$sentiment = new \PHPInsight\Sentiment();
foreach ($featured as $string) {

    // calculations:
    $scores = $sentiment->score($string);
    $class = $sentiment->categorise($string);

    // output:
    //echo "String: $string\n";
    echo "<br/>";
    echo "Dominant: $class, scores: ";
    print_r($scores);
    echo "\n";
    echo "<br/>";

}

这是我用上面的代码分析后得到的输出。

显性：neg，得分：数组（[neg] =＆gt; 0.5 [neu] =＆gt; 0.25 [pos] =＆gt;   0.25）

显性：pos，得分：数组（[pos] =＆gt; 0.5 [neu] =＆gt; 0.25 [neg] =＆gt;   0.25）

显性：pos，得分：数组（[pos] =＆gt; 0.5 [neu] =＆gt; 0.25 [neg] =＆gt;   0.25）

显性：neg，得分：数组（[neg] =＆gt; 0.667 [neu] =＆gt; 0.167 [pos] =＆gt;   0.167）

显性：neu，得分：数组（[neu] =＆gt; 0.333 [neg] =＆gt; 0.333 [pos] =＆gt;   0.333）

显性：pos，得分：数组（[pos] =＆gt; 0.4 [neg] =＆gt; 0.4 [neu] =＆gt; 0.2   ）

/ code添加sum数组元素组（neg，pos，neu）

$sumArray = array();

foreach ($scores as $k=>$subArray) {
  foreach ($scores as $id=>$value) {
    $sumArray[$id]+=$value;
  }
}

print_r($sumArray)


?>

**输出：

Array ( [pos] => 1.2 [neg] => 1.2 [neu] => 0.6 )**

我希望我的输出像这样加起来三个元素，即neg，pos，neu：

$rating_data = array(
 array('Sentiment', 'sd'),
 array('neg',sum_neg),
 array('pos',sum_pos),
 array('neu',sum_neu),

);

Answer 1

您可以执行以下操作：

$rating_data = array(
    array('Sentiment', 'sd'),
);
foreach ($sumArray as $k => $v) {
    $rating_data[] = array($k, $v);
}

PHP数组和汇总实体
