Perform a deep string replace operation to ensure the values in $search are no longer present
Repeats the replacement operation until it no longer replaces anything so as to remove "nested" values
e.g. $subject = '%0%0%0DDD', $search ='%0D', $result ='' rather than the '%0%0DD' that
str_replace would return
