Change the Array Format - php

Question

I have a page where it prints out this value:
"Firstname","Ana","George","Wilson"
"Lastname","Smith","Spencer","Carey"
"Age","18","20","22"
I get the values of these using file_get_contents and str_getcsv.
$array= str_getcsv($test);
The Array results that I get is this
Array ( [0] =>
"Firstname"
[1] => 'Ana'
[2] => 'George'
[3] => 'Wilson'
"Lastname"
[4] => 'Smith'
[5] => 'Spencer'
[6] => 'Carey'
"Age"
[7] => 18
[8] => 20
[9] => 22
))
Is there anyway I can change the Array format into this?
Array
(
[0] => Array
(
[0] => 'Ana'
[1] => 'George'
[2] => 'Wilson'
)
[1] => Array
(
[0] => 'Smith'
[1] => 'Spencer'
[2] => 'Carey'
)
[2] => Array
(
[0] => 18
[1] => 20
[2] => 22
)
)

Answer 1

Instead of using file_get_contents() and str_getcsv(), i will recomend you to use file()
Do like below:-
<?php
$test = file('test.txt'); // you can add your file url here
echo "<pre/>";print_r($test);// initial array
foreach($test as &$te){
$new_array = explode(',',$te);
unset($new_array[0]);
$te = array_values($new_array);
}
echo "<pre/>";print_r($test); // modified and desired array

Answer 2

To change the given array to a specified format:
$array = ['Firstname' => ['Ana', 'George', 'Wilson'], 'Lastname' => ['Smith', 'Spencer', 'Carey'], 'Age' => [18, 20, 22]];
$new_array = [];
foreach ($array as $key => $value) {
$new_array[] = $value;
}
print_r($new_array);
Array
(
[Firstname] => Array
(
[0] => Ana
[1] => George
[2] => Wilson
)
[Lastname] => Array
(
[0] => Smith
[1] => Spencer
[2] => Carey
)
[Age] => Array
(
[0] => 18
[1] => 20
[2] => 22
)
)
