将 Codeigniter 的 Excel class 从 PHPExcel 转换为 PhpSpreadsheet
Convert Codeigniter's Excel class from PHPExcel to PhpSpreadsheet
我即将使用 Codeigniter 3.1.11 将 PhpExcel 迁移到 Php 电子表格
以前我使用名为 Excel.php 的 PHP class 文件，它有助于使用 Php[=32= 生成 Excel ] 但现在我想使用 Php 电子表格连接它。
代码如下
class Excel extends PHPExcel{
public $alphabet;
/**
* Constructor
*
* Responsible for initializing library class
*
* @access public
* @return void
*/
public function __construct() {
parent::__construct();
$this->alphabet = range('A', 'Z');
$this->alphabet[26] = 'AA';
$this->alphabet[27] = 'AB';
$this->alphabet[28] = 'AC';
$this->alphabet[29] = 'AD';
$this->alphabet[30] = 'AE';
$this->alphabet[31] = 'AF';
$this->alphabet[32] = 'AG';
$this->alphabet[33] = 'AH';
$this->alphabet[34] = 'AI';
$this->alphabet[35] = 'AJ';
$this->alphabet[36] = 'AK';
$this->alphabet[37] = 'AL';
$this->alphabet[38] = 'AM';
}

private function generate_excel_sheet($header_data, $content_data, $column_width = NULL, $column_format = NULL, $border = FALSE){

//Set excel column width
$column_width = array( 'A' => 10, 'B' => 6, 'C' => 30, 'D' => 30, 'E' => 8);

//Generate excel
$this->excel->create_excel($excel_name, $table_data, $sheet_name, $sheet_heading);
}//end function download()
谁能帮助转换它？
谢谢
最后还是自己解决了。我希望它也能帮助其他人。
只是在这里更新 Excel.php 文件是由我编写的，它有助于更轻松地使用 PhpSpreadsheet 库。我曾经将 Excel.php 文件放在 Codeigniter table 结构化库目录中。
