What are the potential pitfalls of using complex and hard-to-understand constructs in PHP functions?

Using complex and hard-to-understand constructs in PHP functions can make the code difficult to maintain, debug, and understand for other developers. It can lead to confusion, errors, and inefficiencies in the codebase. To avoid these pitfalls, it's important to write clear, concise, and easily understandable code. 

// Bad example using hard-to-understand constructs
function complexFunction($data) {
    return array_map(function($item) { return $item * 2; }, array_filter($data, function($item) { return $item % 2 == 0; }));
}

// Good example using clear and concise code
function simpleFunction($data) {
    $filteredData = array_filter($data, function($item) {
        return $item % 2 == 0;
    });

    $doubledData = array_map(function($item) {
        return $item * 2;
    }, $filteredData);

    return $doubledData;
}
