What are some common mistakes when trying to display data in multiple columns in PHP, and how can they be resolved?

Common mistakes when trying to display data in multiple columns in PHP include not properly calculating the number of items per column, not properly iterating over the data to display it in columns, and not handling cases where the number of items is not evenly divisible by the number of columns. To resolve these issues, you can use functions like array_chunk to split the data into equal parts, iterate over each part to display it in columns, and handle any remaining items separately. 

$data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
$numColumns = 3;

// Split data into equal parts based on the number of columns
$chunks = array_chunk($data, ceil(count($data) / $numColumns));

// Display data in columns
echo '<div style="display: flex;">';
foreach ($chunks as $chunk) {
    echo '<div style="flex: 1;">';
    foreach ($chunk as $item) {
        echo $item . '<br>';
    }
    echo '</div>';
}
echo '</div>';
