文档:

Performs 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 to remove "nested" values e.g. $subject = '%0%0%0DDD', $search ='%0D', $result ='' rather than the '%0%0DD' that str_replace would return
