How can trim() and array_map() be used to remove absätze from an array in PHP?

To remove absätze (paragraphs) from an array in PHP, you can use the `array_map()` function in combination with the `trim()` function. `array_map()` applies a given callback function to each element of an array, while `trim()` removes any whitespace characters from the beginning and end of a string. By using `array_map()` with `trim()`, you can remove absätze from each element of the array. 

// Sample array with absätze
$array_with_absatze = ["This is a paragraph.", "This is another paragraph.", "This is a paragraph with absätze.\n\n"];

// Remove absätze using array_map() and trim()
$array_without_absatze = array_map('trim', $array_with_absatze);

// Output the array without absätze
print_r($array_without_absatze);
