In PHP, what are some alternative methods to using implode for reassembling split strings that may contain empty or irregular elements?

When using implode to reassemble split strings that may contain empty or irregular elements, the implode function will ignore empty elements, resulting in unexpected output. To solve this issue, you can use array_filter to remove empty elements before imploding the array. 

// Split string with empty elements
$string = "apple, ,banana, ,cherry";
$splitArray = explode(",", $string);

// Remove empty elements and reassemble the string
$filteredArray = array_filter($splitArray, function($value) {
    return $value !== '';
});
$rejoinedString = implode(",", $filteredArray);

echo $rejoinedString;
