What are some common pitfalls to avoid when trying to output specific subsets of data from a loop in PHP?

One common pitfall to avoid when trying to output specific subsets of data from a loop in PHP is not properly using conditional statements to filter the data. To solve this issue, you can use an if statement within the loop to check for the specific criteria that determine whether the data should be outputted. 

// Example loop with conditional statement to output specific subsets of data
$data = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];

foreach ($data as $value) {
    if ($value % 2 == 0) { // Output only even numbers
        echo $value . "<br>";
    }
}
