PHP批量导入Excel造成网站卡住问题
因用户需要,给网站增加了一项批量导入excel功能,单个excel文件记录大概2万到3万行,20列左右数据,目前测试发现每次导入数据的时候,都会造成网站其他功能短暂卡住无法使用的情况,直至excel全部处理完才可访问。目前每一行记录均通过网站API统一入库(进行一系列的权限、查询、增加、修改、去重、记录日志等操作)。
不知道有什么方法可以改进,使其导入同时不影响其他用户使用,目前想到的办法是将excel解析结果临时保存到xcache,然后分批(30000条/50条=600次)导入。不知是否有更好的办法。

这个问题我也遇到过,不知道楼主遇到的情况是不是和我一样
两个写法都是用的同一个版本的PHPEXCEL,但是不知道为啥第一种会慢很多~
以下是老代码
:
<code>//代码是基于Yii1 set_time_limit(0);//这个一定要 $Excel = CUploadedFile::getInstanceByName("Excel"); $filePath = $Excel->getTempName() . '.' . $Excel->getExtensionName(); $Excel->saveAs($filePath); Yii::import("application.extensions.*"); $excel = new ExcelReader($filePath); foreach ($excel->getWorksheetList() as $worksheet => $value) { $rs = $excel->getWorksheetData($worksheet); if (!empty($rs)) { foreach ($rs as $index => $row) { $name = $row[1]; $phone = $row[2]; //more code... } } </code>
以下是新代码
:
<code>//代码是基于Yii1 set_time_limit(0);//这个一定要 $Excel = CUploadedFile::getInstanceByName("Excel"); $filePath = $Excel->getTempName() . '.' . $Excel->getExtensionName(); $Excel->saveAs($filePath); Yii::import("application.extensions.*"); $PHPExcel = new PHPExcel(); $PHPReader = new PHPExcel_Reader_Excel2007();//如果new的是2007,那么excel必须是2007格式的 $excel = $PHPReader->load($filePath);//引入文件 $excelSheets = $excel->getAllSheets(); $activeSheetNames = $excel->getSheetNames(); foreach ($excelSheets as $SheetIndex => $activeSheet) { $sheetColumnTotal = $activeSheet->getHighestRow(); if($sheetColumnTotal == 0){ continue; } for($i = 2;$i getCell('A'.$i)->getValue(); $phone = $activeSheet->getCell('B'.$i)->getValue(); } } </code>
异步任务队列
上传后生成任务记录,放到队列处理
如果需要处理的数据太多,建议写入一个队列,然后使用后台php—cli队列任务处理进程来异步处理吧。这个有点像我之前做的一个视频上传后加入队列,然后使用后台PHP—cli进程来异步处理视频转码过程的例子。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i. There are 6 yuan in total

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP is a scripting language widely used on the server side, especially suitable for web development. 1.PHP can embed HTML, process HTTP requests and responses, and supports a variety of databases. 2.PHP is used to generate dynamic web content, process form data, access databases, etc., with strong community support and open source resources. 3. PHP is an interpreted language, and the execution process includes lexical analysis, grammatical analysis, compilation and execution. 4.PHP can be combined with MySQL for advanced applications such as user registration systems. 5. When debugging PHP, you can use functions such as error_reporting() and var_dump(). 6. Optimize PHP code to use caching mechanisms, optimize database queries and use built-in functions. 7

In PHP8, match expressions are a new control structure that returns different results based on the value of the expression. 1) It is similar to a switch statement, but returns a value instead of an execution statement block. 2) The match expression is strictly compared (===), which improves security. 3) It avoids possible break omissions in switch statements and enhances the simplicity and readability of the code.
