Methods

adjust()

EDATE.

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

Returns the serial number that represents the date that is the indicated number of months before or after a specified date (the start_date). Use EDATE to calculate maturity dates or due dates that fall on the same day of the month as the date of issue.

Excel Function: EDATE(dateValue,adjustmentMonths)

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

$adjustmentMonths : array<string|int, mixed>|int

The number of months before or after start_date. A positive value for months yields a future date; a negative value yields a past date. Or can be an array of adjustment values

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

Excel date/time serial value, PHP date/time serial value or PHP date/time object, depending on the value of the ReturnDateType flag If an array of values is passed as the argument, then the returned result will also be an array with the same dimensions

lastDay()

EOMONTH.

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

Returns the date value for the last day of the month that is the indicated number of months before or after start_date. Use EOMONTH to calculate maturity dates or due dates that fall on the last day of the month.

Excel Function: EOMONTH(dateValue,adjustmentMonths)

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

$adjustmentMonths : array<string|int, mixed>|int

The number of months before or after start_date. A positive value for months yields a future date; a negative value yields a past date. Or can be an array of adjustment values

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

Excel date/time serial value, PHP date/time serial value or PHP date/time object, depending on the value of the ReturnDateType flag If an array of values 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
