reset() - “Strict Standards: Only variables should be passed by reference” [duplicate]

Answer 1

reset() takes a reference to an array (variable) so it will not work with the result of a function call.

You need to do something like this:

$arr = explode('/', $new_uri);
$page = reset($arr);

However, the array returned by explode() will already have its internal pointer set to the first element. You shouldn't need to call reset at all.
