php实现网站文件批量压缩下载功能_PHP

May 29, 2016 am 11:48 AM

利用php实现将文件批量压缩打包下载,这个过程中将使用到 ZipArchive 这个类,注意使用该类之前,linux需开启zlib,windows需取消php_zip.dll前的注释。下面直接给出一个简单的将文件压缩为 zip 格式的示例。具体用法请查询php相关文档。

<&#63;php 
$filename='test.zip'; //最终生成的文件名(含路径) 
if(file_exists($filename)){ 
  unlink($filename); 
} 
//重新生成文件 
$zip=new ZipArchive(); 
if($zip->open($filename,ZIPARCHIVE::CREATE)!==TRUE){ 
  exit('无法打开文件,或者文件创建失败'); 
} 
$datalist=array('try.php','zip_class.php'); 
foreach($datalist as $val){ 
  if(file_exists($val)){ 
    $zip->addFile($val); 
  } 
} 
$zip->close();//关闭 
if(!file_exists($filename)){ 
  exit('无法找到文件'); //即使创建,仍有可能失败 
} 
Copy after login

以上就是php实现将文件批量压缩打包下载的全部内容,我们也还可以利用php调用linux系统的shell脚本来实现这个功能,这是一个思路,希望大家可以研究研究。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
