What are the potential pitfalls of using the code provided in the forum thread to sort columns in a multidimensional array?

The potential pitfall of using the code provided in the forum thread to sort columns in a multidimensional array is that it sorts the columns independently of each other, which can lead to data misalignment. To solve this issue, you can modify the code to sort the entire multidimensional array based on a specific column. This ensures that the data in each row stays intact and aligned correctly after sorting. 

function sort_multidimensional_array($array, $column) {
    usort($array, function($a, $b) use ($column) {
        return $a[$column] <=> $b[$column];
    });
    
    return $array;
}

// Usage example
$multiArray = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Alice', 'age' => 25],
    ['name' => 'Bob', 'age' => 35]
];

$sortedArray = sort_multidimensional_array($multiArray, 'age');

print_r($sortedArray);
