I'm making an application to remove additive or commonly called Stemming confix stripping. I wanted to make a loop to process stemming in each text file. process stemming I've put them in the loop. making the process the content of each document also I put in a text file. when I run in the browser no error but only the note NULL. what's the solution? I attach my program and program results`it is code
<?php
require_once __DIR__ . '/vendor/autoload.php';
$array_sentence = glob('../../ujicoba/simpantoken/*.txt');
settype($array_sentence, "string");
if(is_array($array_sentence) && is_object($array_sentence))
{
foreach ($array_sentence as $text)
{
$textnormalizer = new src\Sastrawi\Stemmer\Filter\TextNormalizer();
$stemmerFactory = new \Sastrawi\Stemmer\StemmerFactory();
$stemmer = $stemmerFactory->createStemmer();
$content = file_get_contents($text);
$stemmer = $stemmerFactory->createStemmer();
$output = $stemmer->stem(array($content));
echo $output . "\n";
}
}
var_dump($content);
?>

my source code result in browser when running programenter code here
The following code works for stemming:
<?php
include('stopword.php');
$regexRules = array(
'/^be(.*)lah$/',

$stemming = str_ireplace($regexRules,"", $string);
