php:php中使用excel的简单介绍
在工作中需要处理多语言的翻译问题,翻译都是写在excel表格里面。为了处理方便我就保留中文和英文两列。
这样需要将这些数据从excel中取出来,然乎保存在excel的数组中,通过使用循环数组将相应的数据放入到数据库中。
所以工作的第一步就是要将数据从excel中取出来。这里我使用到了一个开源php处理excel类:phpexcel. 该项目的详细信息 http://phpexcel.codeplex.com/ 。
我目前使用的是phpexcel1.7.3版本, 解压缩后里面有一个PHPExcel和PHPExcel.php文件。
我们主要使用那个PHP文件。见下图文件目录结构
这个版本据说是可以支持excel2007,但是我使用2007编辑的xlsx是无法获得该库的支持。于是乎我就将它转化为2003。感觉支持地很好。
下面介绍一下具体的使用:
require_once('./phpexcel1.7.3/PHPExcel.php'); $php_excel_obj = new PHPExcel(); $php_reader = newPHPExcel_Reader_Excel2007(); if(!$php_reader->canRead($file_name)){ $php_reader= new PHPExcel_Reader_Excel5(); if(!$php_reader->canRead($file_name)){ echo'NO Excel!'; } } $php_excel_obj = $php_reader->load($file_name); $current_sheet =$php_excel_obj->getSheet(0);
上面的主要功能是初始化相关的excel类,并装载excel第一个sheet
$all_column =$current_sheet->getHighestColumn(); $all_row =$current_sheet->getHighestRow();
以上分别获得该表格的最大列值(字母表示如:‘G’),和最大的行数(数值表示)
下面将使用循环来讲excel里面的数据读到excel中:
$all_arr = array(); $c_arr = array(); //字符对照表 for($r_i = 1; $r_igetCell($adr)->getValue(); if($c_i== 'A' && empty($value) ) break; if(is_object($value)) $value= $value->__toString(); $c_arr[$c_i]= $value; } $c_arr&& $all_arr[] = $c_arr; }
下面简单地介绍一下phpexcel的写操作,这个操作经常用于将数据库中的数据导入到excel中,便于展示和做成更美观的效果。
require_once('./phpexcel1.7.3/PHPExcel.php'); $excel_obj = new PHPExcel(); $objWriter = newPHPExcel_Writer_Excel5($excel_obj); $excel_obj->setActiveSheetIndex(0); $act_sheet_obj=$excel_obj->getActiveSheet(); $act_sheet_obj->setTitle('sheet'); $act_sheet_obj->setCellValue('A1', '字符串内容'); $act_sheet_obj->setCellValue('A2', 26); $file_name = "output.xls"; $objWriter->save($file_name);
代码很简单, 首先初始化相关的excel写类,然后写入数据,最后保存为xls文件。

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
