rest_is_integer()

rest_is_integer() — Determines if a given value is integer-like. This reports whether the value represents an integer; it does not guarantee that the value can be represented as a native PHP integer. Values whose magnitude exceeds PHP_INT_MAX are still reported as integer-like, even though the (int) cast that rest_sanitize_value_from_schema() applies for the ‘integer’ type cannot round-trip them: an out-of-range numeric *string* saturates to PHP_INT_MAX or PHP_INT_MIN, while an out-of-range *float* is an undefined conversion in PHP that yields an arbitrary wrapped value.

Inputs: $maybe_integer (mixed): The value being evaluated.

Returns bool: True if an integer, otherwise false.
