In PHP, what methods can be used to handle arrays resulting from string manipulation, especially when the array length varies?

When dealing with arrays resulting from string manipulation where the array length varies, it is important to handle the arrays dynamically. One way to achieve this is by using functions like explode() to split the string into an array based on a delimiter. Then, you can use functions like count() to determine the length of the array and loop through the elements as needed. 

// Example code to handle arrays resulting from string manipulation with varying length

$string = "apple,banana,orange";
$array = explode(",", $string);

foreach($array as $item){
    echo $item . "<br>";
}
