How important is it to maintain human-readable code in PHP development?

Maintaining human-readable code in PHP development is crucial for several reasons. It makes the code easier to understand, debug, and maintain for both the original developer and any other developers who may work on the project in the future. Clear and well-organized code also helps to reduce the likelihood of errors and improve overall code quality. 

// Bad example without comments or clear structure
function clc($a){$b=0;for($i=0;$i<count($a);$i++){$b+=$a[$i];}return $b;}

// Good example with comments and clear structure
function calculate_sum($numbers) {
    $sum = 0;
    for ($i = 0; $i < count($numbers); $i++) {
        $sum += $numbers[$i];
    }
    return $sum;
}
