tl;dr: Could add flags to is_array.
In the library I mentioned, if given a 0-indexed, sequentially keyed array
(list), I would sort or merge and pass the result to array_values()...return
same type given of the three options (map, list, dict).
But that might feel more like introducing a new type - rather than having a
native way to check:
is_indexed_array(array $array[, int $flags = PHP_MAP])
SEQUENTIAL
SEQUENTIAL_DESC
STARTS_AT_0
is_associative_array(array $array)
or “array” could come first to create a triple set of is_array functions. Which
brings me to thinking a flag could ge added to is_array.
- no new functions to remember in the SL
- should be able to do in a non-BC way, default argument value of PHP map
- allows type safety fo array keyword while letting developers opt-into another
layer:
ex. using string with specifying string details
function hello(string $arg) {
if (str_starts_with($arg, “wor”)) {
} else {
trigger_error
}
}
Cheers,
Josh
