Methods

day()

DAYOFMONTH.

public static day(mixed $dateValue) : array<string|int, mixed>|int|string

Returns the day of the month, for a specified date. The day is given as an integer ranging from 1 to 31.

Excel Function: DAY(dateValue)

Parameters
$dateValue : mixed

Excel date serial value (float), PHP date timestamp (integer), PHP DateTime object, or a standard date string Or can be an array of date values

Return values
array<string|int, mixed>|int|string

Day of the month If an array of numbers is passed as the argument, then the returned result will also be an array with the same dimensions

month()

MONTHOFYEAR.

public static month(mixed $dateValue) : array<string|int, mixed>|int|string

Returns the month of a date represented by a serial number. The month is given as an integer, ranging from 1 (January) to 12 (December).

Excel Function: MONTH(dateValue)

Parameters
$dateValue : mixed

Excel date serial value (float), PHP date timestamp (integer), PHP DateTime object, or a standard date string Or can be an array of date values

Return values
array<string|int, mixed>|int|string

Month of the year If an array of numbers is passed as the argument, then the returned result will also be an array with the same dimensions

year()

YEAR.

public static year(mixed $dateValue) : array<string|int, mixed>|int|string

Returns the year corresponding to a date. The year is returned as an integer in the range 1900-9999.

Excel Function: YEAR(dateValue)

Parameters
$dateValue : mixed

Excel date serial value (float), PHP date timestamp (integer), PHP DateTime object, or a standard date string Or can be an array of date values

Return values
array<string|int, mixed>|int|string

Year If an array of numbers is passed as the argument, then the returned result will also be an array with the same dimensions

evaluateArrayArguments()

Handles array argument processing when the function accepts multiple arguments, and any of them can be an array argument.

protected static evaluateArrayArguments(callable $method, mixed ...$arguments) : array<string|int, mixed>

Example use for: ROUND() or DATE().

Parameters
$method : callable
$arguments : mixed
Return values
array<string|int, mixed>

evaluateArrayArgumentsIgnore()

Handles array argument processing when the function accepts multiple arguments, and any of them can be an array argument except for the one specified by ignore.

protected static evaluateArrayArgumentsIgnore(callable $method, int $ignore, mixed ...$arguments) : array<string|int, mixed>

Example use for: HLOOKUP() and VLOOKUP(), where argument 1 is a matrix that needs to be treated as a database rather than as an array argument.

Parameters
$method : callable
$ignore : int
$arguments : mixed
Return values
array<string|int, mixed>

evaluateArrayArgumentsSubset()

Handles array argument processing when the function accepts multiple arguments, but only the first few (up to limit) can be an array arguments.

protected static evaluateArrayArgumentsSubset(callable $method, int $limit, mixed ...$arguments) : array<string|int, mixed>

Example use for: NETWORKDAYS() or CONCATENATE(), where the last argument is a matrix (or a series of values) that need to be treated as a such rather than as an array arguments.

Parameters
$method : callable
$limit : int
$arguments : mixed
Return values
array<string|int, mixed>

evaluateArrayArgumentsSubsetFrom()

Handles array argument processing when the function accepts multiple arguments, but only the last few (from start) can be an array arguments.

protected static evaluateArrayArgumentsSubsetFrom(callable $method, int $start, mixed ...$arguments) : array<string|int, mixed>

Example use for: Z.TEST() or INDEX(), where the first argument 1 is a matrix that needs to be treated as a dataset rather than as an array argument.

Parameters
$method : callable
$start : int
$arguments : mixed
Return values
array<string|int, mixed>

evaluateSingleArgumentArray()

Handles array argument processing when the function accepts a single argument that can be an array argument.

protected static evaluateSingleArgumentArray(callable $method, array<string|int, mixed> $values) : array<string|int, mixed>

Example use for: DAYOFMONTH() or FACT().

Parameters
$method : callable
$values : array<string|int, mixed>
Return values
array<string|int, mixed>

initialiseHelper()

private static initialiseHelper(array<string|int, mixed>|false $arguments) : void
Parameters
$arguments : array<string|int, mixed>|false

Can be changed to array for Php8.1+

Return values
void

testFalse()

private static testFalse(mixed $value) : bool
Parameters
$value : mixed
Return values
bool

weirdCondition()

private static weirdCondition(mixed $dateValue) : int
Parameters
$dateValue : mixed

Excel date serial value (float), PHP date timestamp (integer), PHP DateTime object, or a standard date string

Return values
int
