PHP: How can i combine 2 different array into one - php

Question

Is there a way to combine 2 array into one array?
My first array shows the amount calculated money per day.
$ArrayBefore[] = $amountOfTransactions_prDayArrayBefore;
Output:
Array (
[0] => Array (
[09/02] => 102.83
[08/02] => 3852.49
[07/02] => 2619.23
[06/02] => 1135.24
[05/02] => 2391.4
[04/02] => 2376.15
[03/02] => 2760.05
[02/02] => 1946.41
)
)
My second array shows the amount transactions per day.
$ArrayTrans[] = $amountOfTransactions_prDayArrayTrans;
Output:
Array (
[0] => Array (
[09/02] => 2
[08/02] => 30
[07/02] => 30
[06/02] => 15
[05/02] => 36
[04/02] => 31
[03/02] => 28
[02/02] => 14
)
)
Is there a way to combine both of them to one array. I want them to look like this, so i can spit them out in a table.
Array (
[0] => Array (
[09/02] => 102.83 => 2
[08/02] => 3852.49 => 30
[07/02] => 2619.23 => 30
[06/02] => 1135.24 => 15
[05/02] => 2391.4 => 36
[04/02] => 2376.15 => 31
[03/02] => 2760.05 => 28
[02/02] => 1946.41 => 14
)
)

Answer 1

i call first array $a , second array $b
foreach ( $a[0] as $key=>$value )
{
$c[0]["$value"] = $b[0][$key];
}
and
$c = array (size=1)
0 =>
array (size=8)
'102.83' => int 2
'3852.49' => int 30
'2619.23' => int 30
'1135.24' => int 15
'2391.4' => int 36
'2376.15' => int 31
'2760.05' => int 28
'1946.41' => int 14

Answer 2

Use array_merge():
$result = array_merge($ArrayBefore, $ArrayTrans);
EDIT:
Understand that my php is rusty, but how about something along the lines of:
foreach($ArrayBefore[] as $key => $value) {
$tmpPair[$value] = $ArrayTrans[0][$key];
$newArray[$key] = $tmpPair;
}
You may also be able to simplify it
foreach($ArrayBefore[] as $key => $value) {
$newArray[$key][$value] = $ArrayTrans[0][$key];
}
