In what scenarios does the term "Gruppenwechsel" make sense in the context of PHP or MySQL output?

The term "Gruppenwechsel" in the context of PHP or MySQL output typically refers to changing or grouping data based on a certain criteria. This can be useful when you want to organize and display data in a more structured or meaningful way. In PHP, you can achieve this by using loops and conditional statements to group data based on specific conditions. 

// Sample PHP code to demonstrate "Gruppenwechsel" in the context of PHP output

$data = array(
    array('name' => 'John', 'group' => 'A'),
    array('name' => 'Jane', 'group' => 'B'),
    array('name' => 'Alice', 'group' => 'A'),
    array('name' => 'Bob', 'group' => 'B'),
);

$currentGroup = '';
foreach ($data as $row) {
    if ($row['group'] != $currentGroup) {
        echo "<h2>{$row['group']}</h2>";
        $currentGroup = $row['group'];
    }
    echo $row['name'] . "<br>";
}
