Methods

static void
assert($value, string $expected, string $label = 'variable')

Verifies that the value is of expected types separated by pipe.

static void
assertField(array $array, $key, string $expected = null, string $label = "item '%' in array")

Verifies that element $key in array is of expected types separated by pipe.

static bool
is($value, string $expected)

Verifies that the value is of expected types separated by pipe.

static bool
everyIs(iterable $values, string $expected)

Finds whether all values are of expected types separated by pipe.

static bool
isNumber(mixed $value)

Checks if the value is an integer or a float.

static bool
isNumericInt(mixed $value)

Checks if the value is an integer or a integer written in a string.

static bool
isNumeric(mixed $value)

Checks if the value is a number or a number written in a string.

static bool
isCallable(mixed $value)

Checks if the value is a syntactically correct callback.

static bool
isUnicode(mixed $value)

Checks if the value is a valid UTF-8 string.

static bool
isNone(mixed $value)

Checks if the value is 0, '', false or null.

static bool
isMixed()

No description

static bool
isList(mixed $value) deprecated

Checks if a variable is a zero-based integer indexed array.

static bool
isInRange($value, array $range)

Checks if the value is in the given range [min, max], where the upper or lower limit can be omitted (null).

static bool
isEmail(string $value)

Checks if the value is a valid email address. It does not verify that the domain actually exists, only the syntax is verified.

static bool
isUrl(string $value)

Checks if the value is a valid URL address.

static bool
isUri(string $value)

Checks if the value is a valid URI address, that is, actually a string beginning with a syntactically valid schema.

static bool
isType(string $type)

Checks whether the input is a class, interface or trait.

static bool
isPhpIdentifier(string $value)

Checks whether the input is a valid PHP identifier.
