toStrings()

Filters a value down to a list of strings, keeping every string and integer and dropping the rest.

toStrings(mixed $value) : array<int, string>

The value is first passed through toArray() (a bare scalar is wrapped as a single-element list), then walked : string and int items are kept, cast to string ; anything else (float, bool, null, arrays, objects, resources) is dropped.

Parameters
$value : mixed

The value to filter — an array, or a bare scalar wrapped via toArray().
