The array_fill_keys Function
The array_fill_keys function creates an array
and fills it with elements of a specific
value so that the entire array has the same
elements, but different keys. The keys are taken
from the array passed as the first parameter.
Syntax
array_fill_keys(array $keys, mixed $value): array
Example
Let's fill an array with elements containing the text
'x'. The keys for the new array will be passed
as the first parameter:
<?php
$res = array_fill_keys(['a', 'b', 'c'], 'x');
var_dump($res);
?>
Code execution result:
['a' => 'x', 'b' => 'x', 'c' => 'x']
