What are the list of ini_set() function cannot be overridden by php script?
<p>i do not know whether it is possible to override all ini_set() in php script!. For example, we can able to change the ini_set value for memory_limit using php script. But a friend of mine said, it is not possible to set / change value for some ini_set() in php script . Can anybody list that ini_set() functions?</p>

<p>Sorry for my poor English! </p>
