void abstract public Ds\Sequence::set ( int $index , mixed $value )Parameters: This function accepts two parameters as mentioned above and described below:
- $index: It is used to hold the index number where value of sequence to be updated.

<?php
// Create new Sequence
$seq = new \Ds\Vector([1, 2, 3, 4, 5]);
echo("Original Sequence\n");
// Display the Sequence elements
print_r($seq);
// Use set() function to update
// the sequence elements
$seq->set(2, "Geeks");
echo("\nSequence after updating the elements\n");
// Display the Sequence elements
print_r($seq);
?>
<?php // Create new Sequence$seq = new \Ds\Vector([1, 2, 3, 4, 5]); echo("Original Sequence\n"); // Display the Sequence elements print_r($seq); // Use set() function to update// the sequence elements $seq->set(2, "Geeks");echo("\nSequence after updating the elements\n"); // Display the Sequence elements print_r($seq); ?>
Output:
Program 2:
Original Sequence

(
[0] => 1
[1] => 2
[2] => 3
[3] => 4
[4] => 5
)
