Can I use direct call as IOFactory in StyleArray?

[ghost]

I'm learning convert multiple file into one,
according some conditions / names require change the style of some cells,

require '../../vendor/autoload.php';

use PhpOffice\PhpSpreadsheet\Spreadsheet;
use PhpOffice\PhpSpreadsheet\IOFactory;
use PhpOffice\PhpSpreadsheet\Helper\Sample;

$objSpreadSheet = new Spreadsheet();
$objSpreadSheet->getProperties()
	->setCreator("Sales Admin Tools")
	->setLastModifiedBy("Sales Admin Tools")
	->setTitle("Aging Report")
	->setSubject("Aging Report")
	->setDescription("Auto generated by Sales Admin Tools @ Seapower Web Server by Carleton")
	->setKeywords("")
	->setCategory("Report");

$objSpreadSheet->setActiveSheetIndex(0);
$objSpreadSheet->getActiveSheet()->setTitle('Problem Account');

$objSpreadSheet->getActiveSheet()->setCellValue("A1", "Customer ID");
$objSpreadSheet->getActiveSheet()->setCellValue("B1", "Customer Name");
$objSpreadSheet->getActiveSheet()->setCellValue("C1", "Customer Group");
$objSpreadSheet->getActiveSheet()->setCellValue("D1", "Staff");
$objSpreadSheet->getActiveSheet()->setCellValue("E1", "Credit Available");
$objSpreadSheet->getActiveSheet()->setCellValue("F1", "Credit Left");
$objSpreadSheet->getActiveSheet()->setCellValue("G1", "Owe SP");
$objSpreadSheet->getActiveSheet()->setCellValue("H1", "30 Days");
$objSpreadSheet->getActiveSheet()->setCellValue("I1", "60 Days");
$objSpreadSheet->getActiveSheet()->setCellValue("J1", "90 Days");
$objSpreadSheet->getActiveSheet()->setCellValue("K1", "Over 90 Days");
$objSpreadSheet->getActiveSheet()->setCellValue("L1", "Not Yet Due");
$objSpreadSheet->getActiveSheet()->setCellValue("M1", "Reason");
$objSpreadSheet->getActiveSheet()->setCellValue("N1", "Status");

use \PhpOffice\PhpSpreadsheet\Style\Style;
use \PhpOffice\PhpSpreadsheet\Style\Font;
use \PhpOffice\PhpSpreadsheet\Style\Alignment;
use \PhpOffice\PhpSpreadsheet\Style\Border;
use \PhpOffice\PhpSpreadsheet\Style\Fill;

$styleArray = array([
	'font'	=>	[
		'size'	=>	12,
		'color'	=>	'FFFFFF',
	],
	'alignment'	=>	[
		'horizontal'	=>	Alignment::HORIZONTAL_CENTER,
		'vertical'	=>	Alignment::VERTICAL_CENTER,
		'wrapText'	=>	true,
	],
	'borders'	=>	[
		'allBorders'	=>	[
			'borderStyle'	=>	Border::BORDER_MEDIUM,
		],
	],
	'fill'	=>	[
		'fillType'	=>	Fill::FILL_SOLID,
		'startColor'	=>	[
			'argb'	=>	'FF000000',
		],
		'endColor'	=>	[
			'argb'	=>	'FF000000',
		],
	],
]);

$objSpreadSheet->getActiveSheet()->getStyle('A1:N1')->applyFromArray($styleArray);

$objSpreadSheet->setActiveSheetIndex(0);
// Excel 2007 file
$objWriter = IOFactory::createWriter($objSpreadSheet, 'Html');
$fileName = "SP-Problem Account " . date("Y-m-d");
$objWriter->save('php://output');
$objSpreadSheet->disconnectWorksheets();
unset($objSpreadSheet);

In the part of Style setting,
Can I directly call function Alignment and so?
Cuz currently I cannot apply any of them,

also when I've tried change [] >> array()
the following code still not working.

$styleArray = array([
	'font'	=>	array(
		'size'	=>	12,
		'color'	=>	'FFFFFF',
	),
	'alignment'	=>	array(
		'horizontal'	=>	Alignment::HORIZONTAL_CENTER,
		'vertical'	=>	Alignment::VERTICAL_CENTER,
		'wrapText'	=>	true,
	),
	'borders'	=>	array(
		'allBorders'	=>	array(
			'borderStyle'	=>	Border::BORDER_MEDIUM,
		),
	),
	'fill'	=>	array(
		'fillType'	=>	Fill::FILL_SOLID,
		'startColor'	=>	array(
			'argb'	=>	'FF000000',
		),
		'endColor'	=>	array(
			'argb'	=>	'FF000000',
		),
	),
]);

Is there I've done anything wrong?

You did 2 things wrong. You need to remove array( from your assignment to $styleArray, and the font color needs to be an array. The following should work:

$styleArray = [
	'font'	=>	[
		'size'	=>	12,
		'color'	=>	['rgb' =>'FFFFFF'],
	],
	'alignment'	=>	[
		'horizontal'	=>	Alignment::HORIZONTAL_CENTER,
		'vertical'	=>	Alignment::VERTICAL_CENTER,
		'wrapText'	=>	true,
	],
	'borders'	=>	[
		'allBorders'	=>	[
			'borderStyle'	=>	Border::BORDER_MEDIUM,
		],
	],
	'fill'	=>	[
		'fillType'	=>	Fill::FILL_SOLID,
		'startColor'	=>	[
			'argb'	=>	'FF000000',
		],
		'endColor'	=>	[
			'argb'	=>	'FF000000',
		],
	],
];
