How can the PHP.de Wiki on "Gruppenbruch" be helpful in resolving issues related to grouping results in PHP loops?

Issue: When working with loops in PHP, it can be challenging to group results based on certain criteria. This can make it difficult to organize and display data in a structured manner. Solution: One way to address this issue is by using the concept of "Gruppenbruch" or group break. This involves breaking the loop when a certain condition is met, allowing you to group results based on that condition. Example PHP code snippet: 

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

$currentGroup = null;

foreach ($data as $item) {
    if ($item['group'] !== $currentGroup) {
        if ($currentGroup !== null) {
            echo "</div>"; // Close previous group
        }
        echo "<div>{$item['group']}</div>"; // Start new group
        $currentGroup = $item['group'];
    }
    
    echo "<p>{$item['name']}</p>"; // Display item
}

echo "</div>"; // Close last group
