access array element

How would you access the number 10 in the $arr array?

<?php

 

$val = ‘1.2.3.4.5.6.7.8.9.10.11.12’;

 

$arr[] = array(‘a’=>explode(‘.’,$val));

 

?>

Looks like a test or homework question. Can you figure it out by adding the line I put there?

 

 

<?php
 
$val = ‘1.2.3.4.5.6.7.8.9.10.11.12’;
 
$arr[] = array(‘a’=>explode(‘.’,$val));
 
print_r($arr);
?>

First of all, use the correct quotes, your editor is using "smart quotes" and not ordinary single quotes.

 

Then as Boompa suggested you should get

Array
(
    [0] => Array
        (
            [a] => Array
                (
                    [0] => 1
                    [1] => 2
                    [2] => 3
                    [3] => 4
                    [4] => 5
                    [5] => 6
                    [6] => 7
                    [7] => 8
                    [8] => 9
                    [9] => 10
                    [10] => 11
                    [11] => 12
                )

        )

)

Now you can see the indexes you need to provide to access "10"

ah I see so.... $arr[9] would be this element

No. Please look at the structure: You have three nested arrays. $arr has a single element, namely an associative array at index 0. This associative array again has a single element, namely a numerical array at key "a". And this numerical array finally contains the numbers.

 

The number 10 is stored in

$arr[0]['a'][9]
