Answer:

The statement 1. insert is used to insert new tuple value.

Explanation:

We cannot change the tuple values. Tuple is unchangeable, once a tuple is created .

Tuples are immutable, which means it does not allow to update the tuple values.  

There are only two possible ways to change the tuple values.

1. Convert the tuple values into the list
2. Create new tuple values.

We can insert new tuple values .

In PHP, we cannot change the tuple values. Tuple is unchangeable, once a tuple is created. Tuple is also like a liner data structures like lists, arrays, vector and hash table.

Tuple values are finite values and the values are ordered as a sequence and it supports both pack and unpack values.

Tuple has many use cases, that all arranged as an array structure in PHP and it suites for n-tuple’s. Familiar example for this is a record stored in a relational database (i.e user_id, name).
