Your code will output xxx because you are not saving the changes back to the original string. You seem to be confused with how foreach works.

 

str_replace can take an array of replacement words to be replaced by a single string, Your code can be simplified to just:

$words = array("mum","dad","sister","brother");
$string="i got a sister";

echo str_replace($words, 'xxx', $string); // result: i got a xxx
