Multi-dimensional PHP array index - php

Question

I have this array
Array
(
[0] => Array
(
[0] => 1
[1] => 2
)
[1] => Array
(
[0] => 3
[1] => 4
)
[2] => Array
(
[0] => 5
[1] => 6
)
[3] => Array
(
[0] => 7
[1] => 8
)
)
I want this array to be looks like this one:
Array
(
[0] => Array
(
[0] => 1
[1] => 5
)
[1] => Array
(
[0] => 3
[1] => 7
)
[2] => Array
(
[0] => 2
[1] => 6
)
[3] => Array
(
[0] => 4
[1] => 8
)
)
I've spent almost 24 hours to accomplish this task. As you can understand, I need help. Please don't abuse on me by asking what have you tried. Can anyone accomplish this array job? thanks
Edit:
I have this array:
$yourArray = array(
array(1,2),
array(3,4),
array(5,6),
array(7,8),
);
It outputs this one:
Array
(
[0] => Array
(
[0] => 1
[1] => 2
)
[1] => Array
(
[0] => 3
[1] => 4
)
[2] => Array
(
[0] => 5
[1] => 6
)
[3] => Array
(
[0] => 7
[1] => 8
)
)
I want $yourArray to outputs this one:
Array
(
[0] => Array
(
[0] => 1
[1] => 5
)
[1] => Array
(
[0] => 3
[1] => 7
)
[2] => Array
(
[0] => 2
[1] => 6
)
[3] => Array
(
[0] => 4
[1] => 8
)
)
Let me write this too, I get output by using print_r($yourArray). And of course by using keyboard. Hope this helps

Answer 1

Considering what OP has made us understand, and quite seriously, I think this is what you're looking for:
$yourArray = array(
array(1,5),
array(3,7),
array(2,6),
array(4,8),
);
var_dump($yourArray);
Demo.
I really can not understand whether it is serious or not.
Explain yourself.

Answer 2

Here you go:
<?php
$array = array(
array(1,2),
array(3,4),
array(5,6),
array(7,8)
);
function processArray(&$array) {
for ($i = 0; $i < count($array); $i++) {
if ($array[$i][0] > 4) {
$array[$i][0] = $array[$i][0] - 3;
}
if ($array[$i][1] < 5) {
$array[$i][1] = $array[$i][1] + 3;
}
}
}
processArray($array);
print_r($array);
Outputs:
Array ( [0] => Array ( [0] => 1 [1] => 5 ) [1] => Array ( [0] => 3 [1] => 7 ) [2] => Array ( [0] => 2 [1] => 6 ) [3] => Array ( [0] => 4 [1] => 8 ) )

Answer 3

I don't see the pattern so the only possibility I see is doing it by hand.
$foo = [
[1,2],
[3,4],
[5,6],
[7,8]
];
$bar = [
[$foo[0][0],$foo[2][0]],
[$foo[1][0],$foo[3][0]],
[$foo[0][1],$foo[2][1]],
[$foo[1][1],$foo[3][1]]
];
print_r($bar);
Edit
Use array() instead of [ ] if you're using an older version of PHP.
