Something like
$main = [];
$number = 5;
foreach(range(1, $number) as $i) {
$main[] = [ 'value' => '', 'type' => 'col'];

Copy array multiple times
Hello everyone, I would like to do something like this:
$main = []
$number = 5;
[ 'value' => '', 'type' => 'col'] * $number
I want the result to be something like this:
$main = [
0 => [ 'value' => '', 'type' => 'col'],
1 => [ 'value' => '', 'type' => 'col'],
2 => [ 'value' => '', 'type' => 'col'],
3 => [ 'value' => '', 'type' => 'col'],
4 => [ 'value' => '', 'type' => 'col'],
]
The size of new $main array would be depending on the variable $number, which changes.
Is there a way to do this without pushing to the $main array in a loop?

@Sinnbeck thank you for responding. This work great and I've implemented it this way, but I'm wondering if there is a way to get the same result without using a foreach or for loop. Maybe some function in PHP, which multiply array by a number, which I don't know about.

@Abdulsalam it it not native PHP, but for Laravel's Collections it is trivial as I showed below (there is still a foreach but it is abstracted away using map)

@Abdulsalam How about this then
$number = 5;
$main = array_fill(0, $number, [ 'value' => '', 'type' => 'col']);

A one-liner (if you like):
collect()->times(5)->map(fn () => ['value' => '', 'type' => 'col'])->all()

@Abdulsalam yeah, array_fill will be the better option here
