How are the keys assigned in an indexed array in PHP?
- Keys are provided explicitly by the programmer.
- Keys are assigned randomly based on the element's value.
- Keys are assigned automatically by PHP, starting from 0.
- Keys are assigned alphabetically based on the element's value.
In an indexed array in PHP, the keys are assigned automatically by PHP. The first element has a key of 0, the second element has a key of 1, and so on. PHP assigns keys in ascending order, incrementing by 1 for each element. This default behavior ensures that each element in the array has a unique numeric key. It allows for easy access and manipulation of the elements based on their position within the array. Learn more: https://www.php.net/manual/en/language.types.array.php#language.types.array.syntax
