Class PHPStan\Type\IntegerType

Models numeric coercion for arithmetic operators.

Models abs().

Models the (float) cast.

Models the (int) cast.

Models the (string) cast.

Models the (array) cast.

Models PHP's implicit array key coercion: floats truncated to int, booleans become 0/1, null becomes '', numeric strings become int.

Returns how this type might change when passed to a typed parameter or assigned to a typed property. With $strictTypes = true: int widens to int|float (since int is accepted by float parameters in strict mode). With $strictTypes = false: additional coercions apply, e.g. Stringable objects are accepted by string parameters. Used internally to determine what types a value might be coerced to when checking parameter acceptance.

Whether accessing a non-existent offset is safe (won't cause errors). Unlike isOffsetAccessible() which checks if offset access is supported at all.

Returns a list of finite values this type can take. Examples: - for bool: [true, false]

• for int<0, 3>: [0, 1, 2, 3]
• for enums: list of enum cases
• for scalars: the scalar itself For infinite types it returns an empty array.

Models the ** operator.

Performance optimization to skip template resolution when no templates are present.
