What is the Ds\Vector pop() function in PHP?
PHP provides an efficient list implementation in the form of the DS\Vector class. The DS\Vector class is a sequence of values stored in a contiguous buffer. The buffer can resize automatically depending on the number of elements.
This is the most efficient sequential data structure because a value’s index is directly mapped to its index in the buffer. The size of DS\Vector is not bound by any factor or exponent and can be anything.
Ds\Vector::pop()
Ds\Vector::pop removes and returns the last value in the vector.
Syntax
public Ds\Vector::pop(): mixed
Parameters
- None.
Return value
Ds\Vector::pop() returns the last value in the vector.
Code
<?php$myVector = new \Ds\Vector([1, 2, 3]);var_dump($myVector->pop());var_dump($myVector->pop());var_dump($myVector->pop());?>
Output
int(3)
int(2)
int(1)
To run this program, you need to install Data Structures for PHP on your local machine.
In the code above, we create a new vector called myVector and initialize it with some values.
Next, we use the pop() function to remove the last value and return it. It is then printed out using the var_dump method.
