if you want to align only this cells, you can do something like this:

如果你只想对齐这个单元格，你可以这样做：

    $style = array(
        'alignment' => array(
            'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
        )
    );

    $sheet->getStyle("A1:B1")->applyFromArray($style);

But, if you want to apply this style to all cells, try this:

但是，如果要将此样式应用于所有单元格，请尝试以下操作：

    $style = array(
        'alignment' => array(
            'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
        )
    );

    $sheet->getDefaultStyle()->applyFromArray($style);

<?php
    /** Error reporting */
    error_reporting(E_ALL);
    ini_set('display_errors', TRUE);
    ini_set('display_startup_errors', TRUE);
    date_default_timezone_set('Europe/London');

    /** Include PHPExcel */
    require_once '../Classes/PHPExcel.php';

    $objPHPExcel = new PHPExcel();
    $sheet = $objPHPExcel->getActiveSheet();
    $sheet->setCellValueByColumnAndRow(0, 1, "test");
    $sheet->mergeCells('A1:B1');
    $sheet->getActiveSheet()->getStyle('A1:B1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER);
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
    $objWriter->save("test.xlsx");
?>

The solution is to set the cell style through this function:

解决方案是通过此函数设置单元格样式：

$sheet->getStyle('A1')->getAlignment()->applyFromArray(
    array('horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,)
);

<?php
/** Error reporting */
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/London');

/** Include PHPExcel */
require_once '../Classes/PHPExcel.php';

$objPHPExcel = new PHPExcel();
$sheet = $objPHPExcel->getActiveSheet();
$sheet->setCellValueByColumnAndRow(0, 1, "test");
$sheet->mergeCells('A1:B1');
$sheet->getStyle('A1')->getAlignment()->applyFromArray(
    array('horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,)
);
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');
$objWriter->save("test.xlsx");

When using merged columns, I got it centered by using PHPExcel_Style_Alignment::HORIZONTAL_CENTER_CONTINUOUS instead of PHPExcel_Style_Alignment::HORIZONTAL_CENTER

使用合并列时，我使用PHPExcel_Style_Alignment :: HORIZONTAL_CENTER_CONTINUOUS而不是PHPExcel_Style_Alignment :: HORIZONTAL_CENTER使其居中
