PHP 使用 PHPExcel 库生成 Excel 文件

Posted 2020-06-13

phpExcel 是用来操作Office Excel 文档的一个PHP类库，它基于微软的OpenXML标准和PHP语言。可以使用它来读取、写入不同格式的电子表格，如 Excel (BIFF) .xls, Excel 2007 (OfficeOpenXML) .xlsx, CSV, Libre/OpenOffice Calc .ods, Gnumeric, PDF, html等等

 

调用代码示例：

1. $php_excel = new PHPExcel();
2.  
3. $properties = $php_excel->getProperties();
4. $properties->setCreator("www.1024i.com");
5. $properties->setLastModifiedBy("www.loubarnes.com");
6. $properties->setTitle("PHP 生成 Excel");
7. $properties->setSubject("PHP 生成 Excel");
8. $properties->setDescription(‘PHP 生成 Excel‘);
9. $properties->setKeywords("PHP 生成 Excel");
10. $properties->setCategory("PHP 生成 Excel");
11.  
12. $php_excel->setActiveSheetIndex(0);
13. $active_sheet = $php_excel->getActiveSheet();
14.  
15. $active_sheet->setTitle(‘用户‘);
16.  
17. // 自动调节大小
18. $active_sheet->getColumnDimension(‘A‘)->setWidth(8);
19. $active_sheet->getColumnDimension(‘B‘)->setWidth(12);
20. $active_sheet->getColumnDimension(‘C‘)->setWidth(8);
21. $active_sheet->getColumnDimension(‘D‘)->setWidth(8);
22. $active_sheet->getColumnDimension(‘E‘)->setWidth(24);
23. $active_sheet->getColumnDimension(‘F‘)->setWidth(60);
24.  
25. $active_sheet->setCellValue(‘A1‘, ‘PHP 生成 Excel 示例‘ );
26. $active_sheet->mergeCells(‘A1:F1‘); // 合并表头单元格
27. $active_sheet->getRowDimension(1)->setRowHeight(30); // 设置表头1高度
28. $style = array(
29. ‘font‘ => array(
30. ‘size‘ => 20
31. ),
32. ‘alignment‘ => array(
33. ‘horizontal‘ => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
34. ),
35. ‘borders‘ => array(
36. ‘bottom‘ => array(
37. ‘style‘ => PHPExcel_Style_Border::BORDER_THIN
38. )
39. )
40. );
41. $active_sheet->getStyle(‘A1:F1‘)->applyFromArray($style); // 设置表头1样式
42.  
43.  
44.  
45. $active_sheet->getRowDimension(2)->setRowHeight(30); // 设置表头2高度
46. // 设置表头2名称
47. $active_sheet->setCellValue(‘A2‘, ‘编号‘);
48. $active_sheet->setCellValue(‘B2‘, ‘名称‘);
49. $active_sheet->setCellValue(‘C2‘, ‘性别‘);
50. $active_sheet->setCellValue(‘D2‘, ‘年龄‘);
51. $active_sheet->setCellValue(‘E2‘, ‘出生日期‘);
52. $active_sheet->setCellValue(‘F2‘, ‘备注‘);
53.  
54.  
55.  
56. // 表头(编号, 名称, 性别, 出生日期)样式
57. $style = array(
58. ‘font‘ => array(
59. ‘bold‘ => true
60. ),
61. ‘alignment‘ => array(
62. ‘horizontal‘ => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
63. ),
64. ‘borders‘ => array(
65. ‘bottom‘ => array(
66. ‘style‘ => PHPExcel_Style_Border::BORDER_THIN
67. )
68. )
69. );
70. $active_sheet->getStyle(‘A2:E2‘)->applyFromArray($style);
71.  
72. // 表头(备注)样式
73. $style = array(
74. ‘font‘ => array(
75. ‘bold‘ => true
76. ),
77. ‘borders‘ => array(
78. ‘bottom‘ => array(
79. ‘style‘ => PHPExcel_Style_Border::BORDER_THIN
80. )
81. )
82. );
83. $active_sheet->getStyle(‘F2‘)->applyFromArray($style);
84.  
85. // 内容样式
86. $style = array(
87. ‘alignment‘ => array(
88. ‘horizontal‘ => PHPExcel_Style_Alignment::HORIZONTAL_CENTER,
89. )
90. );
91. $active_sheet->getStyle(‘A:E‘)->applyFromArray($style);
92.  
93.  
94.  
95. $ids = post::_ints(‘id‘, array());
96. $notes = post::_strings(‘note‘, array());
97.  
98. $i = 3;
99.  
100. if(count($ids))
101. {
102. foreach($ids as $id)
103. {
104. $note = $notes[$i-3];
106. foreach($this->data as $data)
107. {
108. if($data[‘id‘]==$id)
109. {
110. $active_sheet->setCellValue(‘A‘.$i, $id );
111. $active_sheet->setCellValue(‘B‘.$i, $data[‘name‘] );
112. $active_sheet->setCellValue(‘C‘.$i, $data[‘male‘] );
113. $active_sheet->setCellValue(‘D‘.$i, $data[‘age‘] );
114. $active_sheet->setCellValue(‘E‘.$i, $data[‘birth_date‘] );
115. $active_sheet->setCellValue(‘F‘.$i, $note );
116. break;
117. }
118. }
119. $i++;
120. }
121. }
122.  
123. header(‘Content-Type: application/vnd.ms-excel‘);
124. header(‘Content-Disposition: attachment; filename="用户.xls"‘);
125. $writer = PHPExcel_IOFactory::createWriter($php_excel, ‘Excel5‘);
126. $writer->save(‘php://output‘);

 

官方示例文档中有输出为 PDF 的示例程序：

1. // Change these values to select the Rendering library that you wish to use
2. // and its directory location on your server
3. //$rendererName = PHPExcel_Settings::PDF_RENDERER_TCPDF;
4. $rendererName = PHPExcel_Settings::PDF_RENDERER_MPDF;
5. //$rendererName = PHPExcel_Settings::PDF_RENDERER_DOMPDF;
6. //$rendererLibrary = ‘tcPDF5.9‘;
7. $rendererLibrary = ‘mPDF5.4‘;
8. //$rendererLibrary = ‘domPDF0.6.0beta3‘;
9. $rendererLibraryPath = dirname(__FILE__).‘/../../../libraries/PDF/‘ . $rendererLibrary;
10.  
11.  
12. // ..........
13.  
14.  
15. if (!PHPExcel_Settings::setPdfRenderer(
16. $rendererName,
17. $rendererLibraryPath
18. )) {
19. die(
20. ‘NOTICE: Please set the $rendererName and $rendererLibraryPath values‘ .
21. ‘<br />‘ .
22. ‘at the top of this script as appropriate for your directory structure‘
23. );
24. }
25.  
26.  
27. // Redirect output to a client’s web browser (PDF)
28. header(‘Content-Type: application/pdf‘);
29. header(‘Content-Disposition: attachment;filename="01simple.pdf"‘);
30. header(‘Cache-Control: max-age=0‘);
31.  
32. $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, ‘PDF‘);
33. $objWriter->save(‘php://output‘);

 使用这段代码时需要引入PHP 版本的 PDF 库，支持三个版本的：

1. //$rendererName = PHPExcel_Settings::PDF_RENDERER_TCPDF;
2. $rendererName = PHPExcel_Settings::PDF_RENDERER_MPDF;
3. //$rendererName = PHPExcel_Settings::PDF_RENDERER_DOMPDF;

即 TCPDF, MPDF，DOMPDF，官方网址分别是：

http://www.tcpdf.org/ 
http://www.mpdf1.com/mpdf/ 
https://github.com/dompdf/dompdf

推荐使用TCPDF，下载后复制到项目中，然后代码中 $rendererLibraryPath 改为对应的路径，然后就可以正常输出 PDF 文档了。

对于网上很多用户反映的 PDF 中文乱码问题，解决方法如下：

1. 所有程序及文档全部使用 UTF-8 编码
2. 在 tcpdf_autoconfig.php 中设置中文字库。
