The following function may be useful to create columns from all values of indexed arrays:
<?php
function array_column_all(array $arrays): array
{
$output = [];
$columnCount = count($arrays[0]);
for ($i = 0; $i < $columnCount; $i++)
{
$output [] = array_column($arrays, $i);
}
return $output;
}
?>
Use:
-----
<?php
array_column_all(
[
['A1', 'A2', 'A3'],
['B1', 'B2', 'B3'],
['C1', 'C2', 'C3'],
]
);
?>
This will output:
-------------------
Array
(
[0] => Array
(
[0] => A1
[1] => B1
[2] => C1
)
[1] => Array
(
[0] => A2
[1] => B2
[2] => C2
)
[2] => Array
(
[0] => A3
[1] => B3
[2] => C3
)
)
