The get() method of PHP’s DS\Vector class returns the value stored at a particular vector index.

The process is illustrated below:

The prototype of the get() method is shown below:

mixed public Ds\Vector::get( int ＄index )


## Parameters

The get() method takes a mandatory parameter, i.e., the vector index whose value is returned.

If the index is outside the valid range of indices for the vector, the get() method throws the OutOfRangeException.

## Return value

The get() method returns the value at the specified vector index.

## Example

The code below shows how the get() method works in PHP:

<?php// initialize vector$newVector = new \Ds\Vector([1, "abc", 10, 2, "efg"]);print_r($newVector);for ($i = 0;$i < 5; $i++){ // get value at each index$value = $newVector->get($i);    print("The value at index " . $i . " is " .$value . ".\n");}?>

The code above produces the following output:

Ds\Vector Object
(
[0] => 1
[1] => abc
[2] => 10
[3] => 2
[4] => efg
)
The value at index 0 is 1.
The value at index 1 is abc.
The value at index 2 is 10.
The value at index 3 is 2.
The value at index 4 is efg.


Note: To run this program, you need to install Data Structures for PHP on your local machine.

## Explanation

The vector newVector is initialized with $5$ distinct values of different data types.

The for-loop proceeds to iterate over each vector index. The get() method in line $10$ is invoked during each loop iteration. Each sector value is fetched and output accordingly.
