How can you keep the first 5 letters of each word in a variable and remove the rest?

To keep the first 5 letters of each word in a variable and remove the rest, you can use the `substr` function in PHP to extract the first 5 characters of each word. You can split the input string into an array of words using `explode`, then iterate over each word, extract the first 5 letters using `substr`, and store the result in a new array. Finally, you can join the array back into a string using `implode`.

$input = "Lorem ipsum dolor sit amet";
$words = explode(" ", $input);
$result = [];

foreach ($words as $word) {
    $result[] = substr($word, 0, 5);
}

$output = implode(" ", $result);
echo $output;
