Mix arrays together - php

Question

I have this PHP array:
Array(
[0] => Array(
["Import"]=> Array
(
[0] => 1.00
[1] => 2.00
[2] => 1.00
[3] => 9.00
)
["Page"] => Array
(
[0] => 1
[1] => 4
[2] => 5
[3] => 6
)
["Key"] => Array
(
[0] => 1
[1] => 22
[2] => 88
[3] => 3
)
)
)
I need to get:
Array(
[0] => Array(
[0] => Array(
["Import"] => 1.00
["Page"] => 1
["Key"] => 1
)
[1] => Array(
["Import"] => 2.00
["Page"] => 4
["Key"] => 22
)
[2] => Array(
["Import"] => 1.00
["Page"] => 5
["Key"] => 88
)
[3] => Array(
["Import"] => 9.00
["Page"] => 6
["Key"] => 3
)
)
)
I've checked array_merge and array_combine but I can't find a way to use them in this case.
How can I do?

Answer 1

Try this. Seems to work as you expect.
<?php
$source = array(
array(
'Imports' => array(
1.00,2.00,1.00, 9.00),
'Page' => array(
1,4,5,6),
'Key' => array(
1,22,88,3)
)
);
print_r($source);
$dest = array();
foreach($source as $key => $src) {
foreach($src as $typeKey => $typeArr) {
foreach($typeArr as $index => $val){
$dest[$key][$index][$typeKey] = $val;
}
}
}
print_r($dest);
?>

In PHP 5.5 you can easily achieve that with array_column() function:
$array = [
'Imports' => ['i0', 'i1'],
'Page' => ['p0', 'p1'],
'Key' => ['k0', 'k1']
];
$i = 0;
$result = array_map(function($x) use ($array, &$i)
{
return array_combine(array_keys($array), array_column($array, $i++));
}, current($array));
//var_dump($result);
-but for earlier versions you'll need to gather your array with foreach like:
$result = [];
foreach($array as $key=>$item)
{
foreach($item as $i=>$value)
{
$result[$i][$key] = $value;
}
}
//var_dump($result);
-you'll need, of course, do that with each element of your parent array (code above is a sample of how to rearrange 2-level array). That, again, can be easily done with array_map()

Something like this:
function switchKeys(Array $input) {
$result = array();
foreach ($input as $field => $data) {
if (is_array($data)) {
foreach ($data as $index => $value) {
$result[$index][$field] = $value;
}
}
}
return $result;
}
$input = array(
"imports" => array(1.00, 2.00, 1.00, 9.00,),
"page" => array(1, 4, 5, 6,),
"key" => array(1, 22, 88, 3,),
);
$output = switchKeys($input);
var_export($input);
var_export($output);
Note that your input array has one more level, so you should call the function for each sub array
