What is the function of array_diff() in removing absätze from an array in PHP?

The array_diff() function in PHP is used to compare arrays and return the values from the first array that are not present in any of the other arrays. To remove absätze from an array using array_diff(), you can create a new array containing the absätze you want to remove, and then use array_diff() to filter them out from the original array.

// Original array with absätze
$array = array("apple", "banana", "absatz1", "absatz2", "orange");

// Array containing absätze to remove
$absatzArray = array("absatz1", "absatz2");

// Remove absätze from the original array
$result = array_diff($array, $absatzArray);

// Output the result
print_r($result);
