Работа , формирование Excel файлов в PHP

Сначала: установите phpoffice / phpspreadsheet

composer require phpoffice/phpspreadsheet

Подробное описание интерфейса API phpoffice / phpspreadsheet

PhpSpreadsheet предоставляет богатый интерфейс API, который может устанавливать множество атрибутов ячейки и документа, включая стиль, изображение, дату, функцию и многие другие. Короче говоря, лубую таблицу Excel вы сможете сделать с PhpSpreadsheet.

Перед использованием интерфейса API phpoffice / phpspreadsheet убедитесь, что правильные файлы введены и созданы

Use PhpOfficePhpSpreadsheetSpreadsheet;//Introduce files

$spreadsheet = new PhpOffice PhpSpreadsheet Spreadsheet ();// Create a new excel document
$sheet = $spreadsheet - > getActiveSheet (); // Get the object of the current operation sheet

1: Установить шрифт:

$sheet->getStyle('A7:B7')->getFont()->setBold(true)->setName('Arial')
            -> SetSize (10); // Set the cells A7 to B7 to bold, Arial, 10
$sheet - > getStyle ('B1') - > getFont () - > setBold (true); // Set B1 cells to bold type

2: Установить цвет

$sheet - > getStyle ('A1') - > getFont () - > getColor () - > setARGB ( PhpOffice  PhpSpreadsheet  Style  Color:: COLOR_RED); //Set the text color of cell A1 to red

3: Установить длину колонки

$sheet - > getColumnDimension ('A') - > setWidth (20); // Set the width of column A to 20 (characters)
$sheet - > getColumnDimension ('B') - > setAutoSize (true); // Set the width of column B to automatic width
$sheet - > getDefaultColumnDimension () - > setWidth (12); // Set default column width to 12

4: Установить высоту строки

$sheet - > getRowDimension ('10') - > setRowHeight (100); /// Set the height of the tenth line to 100pt
$sheet - > getDefaultRowDimension () - > setRowHeight (15); // Set default row height to 15

5:Выравнивание

$sheet->getStyle('A:D')->getAlignment()
            -> SetVertical ( PhpOffice PhpSpreadsheet Style Alignment:: VERTICAL_CENTER) /// Set Vertical Centralization
            -> SetHorizontal ( PhpOffice PhpSpreadsheet Style Alignment:: HORIZONTAL_CENTER)/// Settings are in the middle
            -> setWrapText (true); // Set automatic line break

6: Объединение ячеек

$sheet - > mergeCells ('A1: D2'); //A1 to D2 merged into one cell

7: Разделить объединенные ячейки

$sheet - > unmergeCells ('A1: D2'); // Split the merged cells.

8: Используйте applyFromArray для реализации настроек стиля ячейки

// Style variables
$style = [
// Setting font style
'font' => [
        'name' => 'Arial',
        'bold' => true,
        'italic' => false,
        'underline' => Font::UNDERLINE_DOUBLE,
        'strikethrough' => false,
        'color' => [
            'rgb' => '808080'
        ]
    ],
// Set the border style
'borders' => [
         // All Borders Border Styles
         // Left border
       'bottom' => [
           'borderStyle' => Border::BORDER_DASHDOT,
           'color' => [
              'rgb' => '808080'
            ]
       ],
         // Upper border
       'top' => [
           'borderStyle' => Border::BORDER_DASHDOT,
           'color' => [
               'rgb' => '808080'
           ]
       ]
],
// Alignment Style
'alignment' => [
   'horizontal' => Alignment::HORIZONTAL_CENTER,
   'vertical' => Alignment::VERTICAL_CENTER,
   'wrapText' => true,
],
// Whether to use prefix
'quotePrefix'    => true
];
$sheet->getStyle('A1:D1')->applyFromArray($style);

9: Установка заголовка рабочего листа

$sheet - > setTitle ('Hello'); and // Set the current worksheet title.

10: Формат ячеек

$sheet->getStyle('D2')->getNumberFormat()
            -> setFormatCode ( PhpOffice PhpSpreadsheet Style NumberFormat:: FORMAT_TEXT); // Set the format of D2 cells to text format
$sheet->getStyle('A1:D2')->getNumberFormat()
            -> setFormatCode ( PhpOffice PhpSpreadsheet Style NumberFormat:: FORMAT_TEXT); // Set cells A1 to D2 to text format

11: Смена линии

$sheet - > getCell ('A4') - > setValue ("hello nworld"); and // wrap the hello and world lines of cells A4

12: Гиперссылки

// Set up the A2 cell content blog and click jump https://www.wj0511.com
$sheet->setCellValue('A2', 'blog');
$sheet->getCell('A2')->getHyperlink()->setUrl('https://www.wj0511.com');

13: Используйте функции

Общие функции : sum (SUM), maximum (MAX), minimum (MIN), average (AVERAGE).

$sheet - > setCellValue ('B5','= SUM (B1: B4)'); and // Set the contents of B5 cells to the sum of B1 to B4

14: Три: Простая реализация генерации Excel (здесь я загружаю фреймворк Yii методом загрузки)

$spreadsheet->getProperties()
    -> setCreator ("author"//author)
    -> setLastModifiedBy ("last-author")// Last ModifiedBy
    -> setTitle ("title")// title
    -> setSubject ("subject"// subtitle
    -> setDescription ("description"//description)
    -> setKey ("keywords") // keyword
    -> setCategory ("category"); //classification

Three: Simple implementation of Excel generation (here I download the Yii framework with the download method)

// Read the first worksheet
$whatTable = 0;

$highest_row = $sheet - > get Highest Row (); // Get the total number of rows
$highest_column = $sheet - > getHighestColumn (); /// Gets the column numeral abc...
