How can PHP functions like explode, array_filter, and join be used together to manipulate strings efficiently?

To manipulate strings efficiently using PHP functions like explode, array_filter, and join, you can first use explode to split the string into an array based on a delimiter. Then, use array_filter to remove any unwanted elements from the array. Finally, use join to concatenate the remaining elements back into a string. 

$string = "apple,banana, ,orange,";
$delimiter = ',';
$array = explode($delimiter, $string);
$array = array_filter($array, function($value) {
    return trim($value) !== ''; // Remove empty elements
});
$newString = join($delimiter, $array);
echo $newString; // Output: "apple,banana,orange"
