What strategies can be employed to troubleshoot issues with storing loop results in PHP variables, especially when unexpected behavior occurs?

When storing loop results in PHP variables, unexpected behavior may occur due to variable scope or data manipulation within the loop. To troubleshoot such issues, ensure that variables are properly initialized outside the loop, use appropriate data types, and avoid overwriting variable values unintentionally within the loop.

// Initialize an empty array to store loop results
$results = [];

// Loop through data and store results in the array
foreach ($data as $item) {
    // Perform any necessary operations on $item
    $processedItem = processData($item);
    
    // Store processed item in the results array
    $results[] = $processedItem;
}

// Use $results array for further processing or output
