PHP uses PHPexcel to import and export data, phpexcel imports and exports
This article describes the example of PHP using PHPexcel to import and export data. Share it with everyone for your reference, the details are as follows:
Import data:
<?php error_reporting(E_ALL); //开启错误 set_time_limit(0); //脚本不超时 date_default_timezone_set('Europe/London'); //设置时间 /** Include path **/ set_include_path(get_include_path() . PATH_SEPARATOR . 'http://www.bkjia.com/../Classes/');//设置环境变量 /** PHPExcel_IOFactory */ include 'PHPExcel/IOFactory.php'; //$inputFileType = 'Excel5'; //这个是读 xls的 $inputFileType = 'Excel2007';//这个是计xlsx的 //$inputFileName = './sampleData/example2.xls'; $inputFileName = './sampleData/book.xlsx'; echo 'Loading file ',pathinfo($inputFileName,PATHINFO_BASENAME),' using IOFactory with a defined reader type of ',$inputFileType,'<br />'; $objReader = PHPExcel_IOFactory::createReader($inputFileType); $objPHPExcel = $objReader->load($inputFileName); /* $sheet = $objPHPExcel->getSheet(0); $highestRow = $sheet->getHighestRow(); //取得总行数 $highestColumn = $sheet->getHighestColumn(); //取得总列 */ $objWorksheet = $objPHPExcel->getActiveSheet();//取得总行数 $highestRow = $objWorksheet->getHighestRow();//取得总列数 echo 'highestRow='.$highestRow; echo "<br>"; $highestColumn = $objWorksheet->getHighestColumn(); $highestColumnIndex = PHPExcel_Cell::columnIndexFromString($highestColumn);//总列数 echo 'highestColumnIndex='.$highestColumnIndex; echo "<br />"; $headtitle=array(); for ($row = 1;$row <= $highestRow;$row++) { $strs=array(); //注意highestColumnIndex的列数索引从0开始 for ($col = 0;$col < $highestColumnIndex;$col++) { $strs[$col] =$objWorksheet->getCellByColumnAndRow($col, $row)->getValue(); } $info = array( 'word1'=>"$strs[0]", 'word2'=>"$strs[1]", 'word3'=>"$strs[2]", 'word4'=>"$strs[3]", ); //在这儿,你可以连接,你的数据库,写入数据库了 print_r($info); echo '<br />'; } ?>
Export data:
(If there is a special string = trouble str_replace(array('='),'',$val['roleName']);)
private function _export_data($data = array()) { error_reporting(E_ALL); //开启错误 set_time_limit(0); //脚本不超时 date_default_timezone_set('Europe/London'); //设置时间 /** Include path **/ set_include_path(FCPATH.APPPATH.'/libraries/Classes/');//设置环境变量 // Create new PHPExcel object Include 'PHPExcel.php'; $objPHPExcel = new PHPExcel(); // Set document properties $objPHPExcel->getProperties()->setCreator("Maarten Balliauw") ->setLastModifiedBy("Maarten Balliauw") ->setTitle("Office 2007 XLSX Test Document") ->setSubject("Office 2007 XLSX Test Document") ->setDescription("Test document for Office 2007 XLSX, generated using PHP classes.") ->setKeywords("office 2007 openxml php") ->setCategory("Test result file"); // Add some data $letter = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'); if($data){ $i = 1; foreach ($data as $key => $value) { $newobj = $objPHPExcel->setActiveSheetIndex(0); $j = 0; foreach ($value as $k => $val) { $index = $letter[$j]."$i"; $objPHPExcel->setActiveSheetIndex(0)->setCellValue($index, $val); $j++; } $i++; } } $date = date('Y-m-d',time()); // Rename worksheet $objPHPExcel->getActiveSheet()->setTitle($date); $objPHPExcel->setActiveSheetIndex(0); // Redirect output to a client's web browser (Excel2007) header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'); header('Content-Disposition: attachment;filename="'.$date.'.xlsx"'); header('Cache-Control: max-age=0'); $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007'); $objWriter->save('php://output'); exit; }
Go directly to the code:
public function export_data($data = array()) { # code... include_once(APP_PATH.'Tools/PHPExcel/Classes/PHPExcel/Writer/IWriter.php') ; include_once(APP_PATH.'Tools/PHPExcel/Classes/PHPExcel/Writer/Excel5.php') ; include_once(APP_PATH.'Tools/PHPExcel/Classes/PHPExcel.php') ; include_once(APP_PATH.'Tools/PHPExcel/Classes/PHPExcel/IOFactory.php') ; $obj_phpexcel = new PHPExcel(); $obj_phpexcel->getActiveSheet()->setCellValue('a1','Key'); $obj_phpexcel->getActiveSheet()->setCellValue('b1','Value'); if($data){ $i =2; foreach ($data as $key => $value) { # code... $obj_phpexcel->getActiveSheet()->setCellValue('a'.$i,$value); $i++; } } $obj_Writer = PHPExcel_IOFactory::createWriter($obj_phpexcel,'Excel5'); $filename = "outexcel.xls"; header("Content-Type: application/force-download"); header("Content-Type: application/octet-stream"); header("Content-Type: application/download"); header('Content-Disposition:inline;filename="'.$filename.'"'); header("Content-Transfer-Encoding: binary"); header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Pragma: no-cache"); $obj_Writer->save('php://output'); }
I hope this article will be helpful to everyone in php programming design.

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
