Below programs illustrate the Ds\Sequence::insert() function in PHP:
Program 1:

Output:
object(Ds\Vector)#1 (6) {
[0] => string(1) "g"
[1] => string(1) "e"
[2] => string(1) "e"
[3] => string(1) "k"
[4] => string(1) "s"
[5] => int(4)
}
Program 2:
<?php // Create new sequence $seq = new \Ds\Vector(); // Use insert() function to insert // element in the sequence $seq->insert(0, 1, 2, 3, 4, 5, ["g", "e", "e", "k", 1, 2]); var_dump($seq); ?> |
Output:
object(Ds\Vector)#1 (6) {
[0] => int(1)
[1] => int(2)
[2] => int(3)
[3] => int(4)
[4] => int(5)
[5] => array(6) {
[0] => string(1) "g"
[1] => string(1) "e"
[2] => string(1) "e"
[3] => string(1) "k"
[4] => int(1)
[5] => int(2)
}
