This article mainly introduces the code for exporting data and pictures using PHPEXCEL. It has certain reference value. Now I share it with you. Friends in need can refer to it
Preface
Pictures are an object to excel and cannot be exported to cells normally, so everyone is confused about how to use PHP language to export! Below I will explain in detail how to use php to export pictures to excel (this example uses the CI framework)
Note: This is for the CI project, other frameworks are placed in the class library Just go inside
Upload the code
//CI框架引入PHPExcel $this->load->library('PHPExcel');//实例化PHPExcel类 $objPHPExcel = new PHPExcel();//图片处理类,这个才是图片导出的关键哦 $objDrawing = new PHPExcel_Worksheet_Drawing();//然后正常设置我们导出图片的代码 $objPHPExcel->createSheet(0); $objPHPExcel->setActiveSheetIndex(0); $currentSheet = $objPHPExcel->getActiveSheet();// 水平居中(位置很重要,建议在最初始位置,这里我举例,ABCDEFG,可以按照自己的需求定义!~) $objPHPExcel->setActiveSheetIndex(0)->getStyle('A')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->setActiveSheetIndex(0)->getStyle('B')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->setActiveSheetIndex(0)->getStyle('C')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->setActiveSheetIndex(0)->getStyle('D')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->setActiveSheetIndex(0)->getStyle('E')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->setActiveSheetIndex(0)->getStyle('F')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER); $objPHPExcel->setActiveSheetIndex(0)->getStyle('G')->getAlignment()->setHorizontal(\PHPExcel_Style_Alignment::HORIZONTAL_CENTER);// 设置个表格宽度(这个一定要设置哦,不然图片会大厨单元格的) $objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(20); $objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(20); $objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(20); $objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(20); $objPHPExcel->getActiveSheet()->getColumnDimension('E')->setWidth(20); $objPHPExcel->getActiveSheet()->getColumnDimension('F')->setWidth(20); $objPHPExcel->getActiveSheet()->getColumnDimension('G')->setWidth(20);//设置第一行标题 $currentSheet->setCellValue('A1', "序列号"); $currentSheet->setCellValue('B1', "设备ID"); $currentSheet->setCellValue('C1', "设备密码"); $currentSheet->setCellValue('D1', "设备编码"); $currentSheet->setCellValue('E1', "二维码"); $currentSheet->setCellValue('F1', "二维码"); $currentSheet->setCellValue('G1', "二维码");//定义变量初始化为2,从第二行开始 $idx = 2;//开始循环数组数据!~ foreach ($devices as $device) { //设置数据所在单元格,我这里把图片放在E里 $currentSheet->setCellValue('A' . $idx, $device['sequence']); $currentSheet->setCellValue('B' . $idx, $device['device_unique']); $currentSheet->setCellValue('C' . $idx, $device['device_pwd']); $currentSheet->setCellValue('D' . $idx, $device['device_code']); //设置单元格高度,这个是重点哦 $currentSheet->getRowDimension($idx) -> setRowHeight(60) //获取图片 $this->load->model('Device_codes_model'); $codes = $this->Device_codes_model->getOneCodes($id); //开始设置图片啦~~ $objDrawing->setPath($codes['code_file']); // 设置图片宽度高度 $objDrawing->setHeight(80);//照片高度 $objDrawing->setWidth(80); //照片宽度 /*设置图片要插入的单元格*/ $objDrawing->setCoordinates('E'.$idx); // 图片偏移距离 $objDrawing->setOffsetX(12); $objDrawing->setOffsetY(12); $objDrawing->setWorksheet($objPHPExcel->getActiveSheet()); $idx++; }//导出excel到表格 $sheetWrite = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.

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.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
