PhpExcel中文使用方法
<p>PHPExcel基本操作:<br> 定义EXCEL实体<br> 即定义一个PHPEXCEL对象,并设置EXCEL对象内显示内容</p> <div> <pre class='brush:php;toolbar:false;'> // Excel开始 // 准备EXCEL的包括文件 // Error reporting error_reporting(0); // PHPExcel require_once dirname(__FILE__) . 'PHPExcel.php'; // 生成新的excel对象 $objPHPExcel = new PHPExcel(); // 设置excel文档的属性 $objPHPExcel->getProperties()->setCreator("Sam.c") ->setLastModifiedBy("Sam.c Test") ->setTitle("Microsoft Office Excel Document") ->setSubject("Test") ->setDescription("Test") ->setKeywords("Test") ->setCategory("Test result file"); // 开始操作excel表 // 操作第一个工作表 $objPHPExcel->setActiveSheetIndex(0); // 设置工作薄名称 $objPHPExcel->getActiveSheet()->setTitle(iconv('gbk', 'utf-8', 'phpexcel测试')); // 设置默认字体和大小 $objPHPExcel->getDefaultStyle()->getFont()->setName(iconv('gbk', 'utf-8', '宋体')); $objPHPExcel->getDefaultStyle()->getFont()->setSize(10);
三、输出文件
// 如果需要输出EXCEL格式 if($m_exportType=="excel"){ $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5'); // 从浏览器直接输出$filename header("Pragma: public"); header("Expires: 0"); header("Cache-Control:must-revalidate, post-check=0, pre-check=0"); header("Content-Type:application/force-download"); header("Content-Type: application/vnd.ms-excel;"); header("Content-Type:application/octet-stream"); header("Content-Type:application/download"); header("Content-Disposition:attachment;filename=".$filename); header("Content-Transfer-Encoding:binary"); $objWriter->save("php://output"); } // 如果需要输出PDF格式 if($m_exportType=="pdf"){ $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'PDF'); $objWriter->setSheetIndex(0); header("Pragma: public"); header("Expires: 0"); header("Cache-Control:must-revalidate, post-check=0, pre-check=0"); header("Content-Type:application/force-download"); header("Content-Type: application/pdf"); header("Content-Type:application/octet-stream"); header("Content-Type:application/download"); header("Content-Disposition:attachment;filename=".$m_strOutputPdfFileName); header("Content-Transfer-Encoding:binary"); $objWriter->save("php://output"); }
设置一列的宽度:
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(15);
设置一行的高度:
$objPHPExcel->getActiveSheet()->getRowDimension('6')->setRowHeight(30);
合并单元格:
$objPHPExcel->getActiveSheet()->mergeCells('A1:P1');
设置A1单元格加粗,居中:
$styleArray1 = array( 'font' => array( 'bold' => true, 'size'=>12, 'color'=>array( 'argb' => '00000000', ), ), 'alignment' => array( 'horizontal' => PHPExcel_Style_Alignment::HORIZONTAL_CENTER, ), ); // 将A1单元格设置为加粗,居中 $objPHPExcel->getActiveSheet()->getStyle('A1')->applyFromArray($styleArray1); $objPHPExcel->getActiveSheet()->getStyle('B1')->getFont()->setBold(true);
给特定单元格中写入内容:
$objPHPExcel->getActiveSheet()->setCellValue('A1', 'Hello Baby');
设置单元格样式(水平/垂直居中):
$objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->getActiveSheet()->getStyle('A1')->getAlignment()->setVertical(PHPExcel_Style_Alignment::VERTICAL_CENTER);
设置单元格样式(黑色字体):
$objPHPExcel->getActiveSheet()->getStyle('H5')->getFont()->getColor()->setARGB(PHPExcel_Style_Color::COLOR_BLACK); // 黑色
设置单元格格式(背景):
$objPHPExcel->getActiveSheet()->getStyle('H5')->getFill()->getStartColor()->setARGB('00ff99cc'); // 将背景设置为浅粉色
设置单元格格式(数字格式):
$objPHPExcel->getActiveSheet()->getStyle('F'.$iLineNumber)->getNumberFormat()->setFormatCode('0.000');
给单元格中放入图片:
// 将数据中心图片放在J1单元格内 $objDrawing = new PHPExcel_Worksheet_Drawing(); $objDrawing->setName('Logo'); $objDrawing->setDescription('Logo'); $objDrawing->setPath('test.jpg'); $objDrawing->setWidth(400); $objDrawing->setHeight(123); $objDrawing->setCoordinates('J1'); $objDrawing->setWorksheet($objPHPExcel->getActiveSheet());
在单元格中设置超链接:
$objPHPExcel->getActiveSheet()->setCellValue('H8', iconv('gbk', 'utf-8', '燕南天')); $objPHPExcel->getActiveSheet()->getCell('H8')->getHyperlink()->setUrl('http://www.bitsCN.com/');
设置单元格边框
$styleThinBlackBorderOutline = array( 'borders' => array ( 'outline' => array ( 'style' => PHPExcel_Style_Border::BORDER_THIN, //设置border样式 //'style' => PHPExcel_Style_Border::BORDER_THICK, 另一种样式 'color' => array ('argb' => 'FF000000'), //设置border颜色 ), ), ); $objPHPExcel->getActiveSheet()->getStyle( 'A4:E10')->applyFromArray($styleThinBlackBorderOutline); //添加一个新的worksheet $objExcel->createSheet(); $objActSheet = $objExcel->getSheet($s); $objActSheet->setTitle('表'.$GSheet);

To protect the application from session-related XSS attacks, the following measures are required: 1. Set the HttpOnly and Secure flags to protect the session cookies. 2. Export codes for all user inputs. 3. Implement content security policy (CSP) to limit script sources. Through these policies, session-related XSS attacks can be effectively protected and user data can be ensured.

Methods to optimize PHP session performance include: 1. Delay session start, 2. Use database to store sessions, 3. Compress session data, 4. Manage session life cycle, and 5. Implement session sharing. These strategies can significantly improve the efficiency of applications in high concurrency environments.

In PHP, you can use the session_name() function to configure the session name. The specific steps are as follows: 1. Use the session_name() function to set the session name, such as session_name("my_session"). 2. After setting the session name, call session_start() to start the session. Configuring session names can avoid session data conflicts between multiple applications and enhance security, but pay attention to the uniqueness, security, length and setting timing of session names.

The session ID should be regenerated regularly at login, before sensitive operations, and every 30 minutes. 1. Regenerate the session ID when logging in to prevent session fixed attacks. 2. Regenerate before sensitive operations to improve safety. 3. Regular regeneration reduces long-term utilization risks, but the user experience needs to be weighed.

Setting session cookie parameters in PHP can be achieved through the session_set_cookie_params() function. 1) Use this function to set parameters, such as expiration time, path, domain name, security flag, etc.; 2) Call session_start() to make the parameters take effect; 3) Dynamically adjust parameters according to needs, such as user login status; 4) Pay attention to setting secure and httponly flags to improve security.

The main purpose of using sessions in PHP is to maintain the status of the user between different pages. 1) The session is started through the session_start() function, creating a unique session ID and storing it in the user cookie. 2) Session data is saved on the server, allowing data to be passed between different requests, such as login status and shopping cart content.

How to share a session between subdomains? Implemented by setting session cookies for common domain names. 1. Set the domain of the session cookie to .example.com on the server side. 2. Choose the appropriate session storage method, such as memory, database or distributed cache. 3. Pass the session ID through cookies, and the server retrieves and updates the session data based on the ID.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
