<?php
​// Create new sequence$seq =  new \Ds\Vector(["G", "E", "E",        "K", "S", "1", "2", 1, 2, 3, 4]);​// Use get() functionvar_dump($seq->get(0));​// Use get() functionvar_dump($seq->get(1));​// Use get() functionvar_dump($seq->get(10));​// Use get() functionvar_dump($seq->get(5));​// Use get() functionvar_dump($seq->get(7));​?>

Output:

string(1) "G"
string(1) "E"
int(4)
string(1) "1"
int(1)

Program 2:

        "K", "S", "1", "2", 1, 2, 3, 4]);

// Declare an index array
$arr = array (0, 1, 4, 6, 8, 5);

// Loop run for every array element  
foreach ($arr as $val) {  

    // Use get() function
    var_dump($seq->get($val));
}

?>

 
<?php
​// Create new sequence$seq =  new \Ds\Vector(["G", "E", "E",        "K", "S", "1", "2", 1, 2, 3, 4]);​// Declare an index array$arr = array (0, 1, 4, 6, 8, 5);​// Loop run for every array element  foreach ($arr as $val) {  ​    // Use get() function    var_dump($seq->get($val));}​?>

string(1) "G"
string(1) "E"
string(1) "S"

string(1) "1"
