一开始使用php调用命令行来执行压缩,后来发现php有ZipArchive类库实现了文件的压缩与解压缩 //递归移动文件到当前目录public function moveZipFiles($path,$aimpath) //把path里的所有文件夹里的文件都移动到path层{//rename(/tmp/tmp_file.txt, /home/user

一开始使用php调用命令行来执行压缩,后来发现php有ZipArchive类库实现了文件的压缩与解压缩

	//递归移动文件到当前目录
	public function moveZipFiles($path,$aimpath)  //把path里的所有文件夹里的文件都移动到path层
	{
		//rename("/tmp/tmp_file.txt", "/home/user/login/docs/my_file.txt");
		$handler = opendir($path);
		while (($filename = readdir($handler)) !== false)
		{
			if($filename != "." && $filename != "..")  //务必使用!==,防止目录下出现类似文件名“0”等情况
			{
				if(is_dir($path.'/'.$filename))  //如果是目录,递归移动
				{
					$this->moveZipFiles($path.'/'.$filename,$aimpath);  //yii的php递归需要加上$this
				}
				else    //如果是文件,则移动到aimpath
				{
					rename($path.'/'.$filename, $aimpath.'/'.$filename);
				}
			}
		}
		closedir($handler);		
	}
	
	//解压上传的bin文件的压缩包
	public function unZip($zipPath,$path)
	{
		$f =new func();
		$zip = new ZipArchive;
		if($zip->open($zipPath)===TRUE){
			$zip->extractTo($path);//假设解压缩到在当前路径下images文件夹内
			$zip->close();//关闭处理的zip文件
		}
		//解压缩完毕删除压缩包
		unlink($zipPath);
		$f->moveZipFiles($path,$path);
	}

方法moveZipFiles是递归的把解压文件夹里面的文件都移动到最外层的目录下,unZip实现了解压,移动,并删除压缩包的功能,其两个参数是压缩包路径和解压路径,一个是文件,一个为目录

而压缩文件,ZipArchive也提供了足够的简单的接口

	public function generateTaskZip($prj_id , $ver_id , $task_id )
	{
		$f = new func();
		$zip = new ZipArchive;
		$task_dir = Yii::getPathOfAlias('webroot').'/projects/'.$prj_id .'/'.$ver_id .'/'.$task_id ;
		$root_dir = Yii::getPathOfAlias('webroot');
		$generatefile_dir = Yii::getPathOfAlias('webroot').'/projects/'.$prj_id .'/'.$ver_id .'/base';
		if($zip->open($task_dir.'/output.zip',ZipArchive::OVERWRITE)===TRUE){
			$zip->addEmptyDir("CC_Log_GUI");
			$zip->addFile($root_dir.'/UI.exe', 'Tools_GUI.exe');
			$zip->addFile($root_dir.'/irst.reg', 'first.reg');
			$zip->addFile($root_dir.'/API.dll', 'API.dll');
			$zip->addFile($root_dir.'/n.dll', 'In.dll');
			
			//把生成的jumpbyList.json打包到zip
			if(!is_dir($generatefile_dir))
			{
				return;
			}
			$handler1 = opendir($generatefile_dir); 
			while (($filename = readdir($handler1)) !== false)
			{//务必使用!==,防止目录下出现类似文件名“0”等情况
				if($filename != "." && $filename != "..")
				{
					$len = strlen($filename);
					if(!substr_compare($filename,'st_',0,19,FALSE))  //把base的文件夹下所有的st_*.json文件都打包到zip包里
					{
						$zip->addFile($generatefile_dir.'/'.$filename,basename($filename));
					}			
				}
			}
			closedir($handler1);
			
			//把flf文件打包到zip包
			if(!is_dir($task_dir))
			{
				return;
			}
			$handler2 = opendir($task_dir);
			while (($filename = readdir($handler2)) !== false)
			{
				if($filename != "." && $filename != "..")      //务必使用!==,防止目录下出现类似文件名“0”等情况
				{
					$len = strlen($filename);
					if(!substr_compare($filename,'.flf',$len-4,4,FALSE)) //如果是flf文件,则需要打包到两个地方,一个是当前目录,另外是CC_Log_GUI/目录
					{                                                         
						$file_name = basename($filename);
						$zip->addFile($task_dir.'/'.$filename,'UI/'.$file_name);
						$zip->addFile($task_dir.'/'.$filename,$file_name);
					}
				}
			}
			closedir($handler2);		
			$zip->close();
		}
		
	}

直接使用addFile就可以简单的把所有指定文件改为指定的名称并打包到zip

现在存在一个问题,如果使用zipArchive压缩文件,怎么能确定它已经把所有文件都压缩好了呢?如果刚开始执行压缩就点击下载zip包,这样zip包里的文件是不完整的,怎么才能提供让zipArchive生成完整的zip文件再提供下载呢

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,

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

Explain the match expression (PHP 8 ) and how it differs from switch. Explain the match expression (PHP 8 ) and how it differs from switch. Apr 06, 2025 am 12:03 AM

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.
