Is there a specific context in PHP or MySQL where the term "Gruppenwechsel" is relevant for outputting terms under headings?

In PHP or MySQL, the term "Gruppenwechsel" (which translates to "group change" in English) is relevant when you want to output terms under specific headings based on a change in group. This is commonly used when you have a dataset that is grouped by a certain criteria, and you want to display the data under different headings for each group. To implement this in PHP, you can use a loop to iterate through the dataset and check for a change in group. When a change is detected, you can output a new heading before displaying the term. Here is an example code snippet: 

<?php

// Sample dataset grouped by "group"
$dataset = [
    ['group' => 'A', 'term' => 'Apple'],
    ['group' => 'A', 'term' => 'Apricot'],
    ['group' => 'B', 'term' => 'Banana'],
    ['group' => 'B', 'term' => 'Blueberry'],
];

$currentGroup = null;

foreach ($dataset as $data) {
    if ($data['group'] !== $currentGroup) {
        echo "<h2>{$data['group']}</h2>";
        $currentGroup = $data['group'];
    }
    
    echo "<p>{$data['term']}</p>";
}

?>
