How can PHP be used to shorten a string by splitting it in half based on word count?

To shorten a string by splitting it in half based on word count in PHP, we can first explode the string into an array of words, then calculate the midpoint of the array to determine where to split the string. We can then use array_slice to extract the first half of the array and implode it back into a string. 

$string = "This is a sample string to be shortened by splitting in half based on word count";
$words = explode(" ", $string);
$midpoint = ceil(count($words) / 2);
$shortenedString = implode(" ", array_slice($words, 0, $midpoint));

echo $shortenedString;
