$initializationNeeded

private static bool $initializationNeeded = true

Methods

fromString()

DATEVALUE.

public static fromString(null|array<string|int, mixed>|bool|float|int|string $dateValue) : array<string|int, mixed>|DateTime|float|int|string

Returns a value that represents a particular date. Use DATEVALUE to convert a date represented by a text string to an Excel or PHP date/time stamp value.

NOTE: When used in a Cell Formula, MS Excel changes the cell format so that it matches the date format of your regional settings. PhpSpreadsheet does not change cell formatting in this way.

Excel Function: DATEVALUE(dateValue)

Parameters
$dateValue : null|array<string|int, mixed>|bool|float|int|string

Text that represents a date in a Microsoft Excel date format. For example, "1/30/2008" or "30-Jan-2008" are text strings within quotation marks that represent dates. Using the default date system in Excel for Windows, date_text must represent a date from January 1, 1900, to December 31, 9999. Using the default date system in Excel for the Macintosh, date_text must represent a date from January 1, 1904, to December 31, 9999. DATEVALUE returns the #VALUE! error value if date_text is out of this range. Or can be an array of date values

Return values
array<string|int, mixed>|DateTime|float|int|string —

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 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>

finalResults()

Final results.

private static finalResults(array<string|int, mixed> $PHPDateArray, DateTimeImmutable $dti, int $baseYear) : DateTime|float|int|string
Parameters
$PHPDateArray : array<string|int, mixed>
$dti : DateTimeImmutable
$baseYear : int
Return values
DateTime|float|int|string —

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

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+

setUpArray()

Parse date.

private static setUpArray(string $dateValue, DateTimeImmutable $dti) : array<string|int, mixed>
Parameters
$dateValue : string
$dti : DateTimeImmutable
Return values
array<string|int, mixed>

t1ToString()

private static t1ToString(array<string|int, mixed> $t1, DateTimeImmutable $dti, bool $yearFound) : string
Parameters
$t1 : array<string|int, mixed>
$dti : DateTimeImmutable
$yearFound : bool
Return values
string

testFalse()

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