这篇文章主要介绍了PHP多文件上传的方法,可实现针对指定后缀文件的批量上传功能,非常具有实用价值,需要的朋友可以参考下
本文实例讲述了PHP多文件上传的方法。分享给大家供大家参考。具体如下:
'文件上传失败,没有错误发生,文件上传成功', 1=>'文件上传失败,上传的文件超过了 php.ini中upload_max_filesize 选项限制的值', 2=>'文件上传失败,上传文件的大小超过了 HTML 表单中 MAX_FILE_SIZE 选项指定的值', 3=>'文件上传失败,文件只有部分被上传', 4=>'文件上传失败,没有文件被上传', 5=>'文件上传失败,未允许的后缀', 6=>'文件上传失败,找不到临时文件夹.PHP 4.3.10 和 PHP 5.0.3 引进', 7=>'文件上传失败,文件写入失败.PHP 5.1.0 引进', 8=>'文件上传失败,未接收到表单域的NAME', 9=>'文件上传失败,,错误未知' ); public static function upload($name){ //检测是否接收到表单域的NAME if(!isset($_FILES[$name])){ self::$wrong[]=8; return false; } //3维数组简化成2维数组 $files=array_shift($_FILES); //获取后缀 $files=self::get_Ext($files); //处理文件次数 $n=count($files['name']); for($i=0;$i'')); } return self::$path; } //获取后缀的方法 protected static function get_Ext($arr){ if(!is_array($arr) || !isset($arr['name'])){return false;} foreach($arr['name'] as $k=>$v){ $arr['name'][$k]=strtolower(strrchr($v,'.')); } return $arr; } //以日期生成路径 protected static function time_Dir(){ $dir=ROOT.'Data/images/'.date('Y/m/d/',time()); if(!is_dir($dir)){ mkdir($dir,0777,true); } return $dir; } //生成随机文件名 protected static function rand_Name(){ $str=str_shuffle('1234567890qwertyuiopasdfghjklzxcvbnm'); $str=substr($str,0,6); return $str; } //错误接口 public static function errors(){ foreach(self::$wrong as $k=>$v){ self::$wrong[$k]='第'.$k.'个'.self::$error[$k]; } return self::$wrong; } }

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.

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

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
