PHP Zip

PHP Zip

Zip archives are files that are compressed using the zip compression algorithm. They are often used to reduce the size of files and make them easier to transfer over the internet or store on disk. A zip archive can contain one or more files, and it typically has a .zip file extension. (ZIP存档是使用ZIP压缩算法压缩的文件。它们通常用于减小文件大小,使其更容易通过互联网传输或存储在磁盘上。ZIP存档可以包含一个或多个文件,并且通常具有.zip文件扩展名。)

PHP Zip Functions

PHP Zip Functions (PHP Zip函数)

PHP provides several built-in functions that allow you to work with zip archives. Some of the most commonly used functions are:

zip_open()

The zip_open() function is used to open a zip archive and create a handle that can be used to read the contents of the archive. (Zip_open ()函数用于打开zip存档并创建可用于读取存档内容的句柄。)

zip_read()

The zip_read() function is used to read the contents of a zip archive file. It returns a zip_entry resource that can be used to get information about the file and extract its contents. (Zip_read ()函数用于读取zip存档文件的内容。它返回一个zip_entry资源,可用于获取有关文件的信息并提取其内容。)

zip_entry_open()

The zip_entry_open() function is used to open a zip_entry resource and create a handle that can be used to extract the contents of the file. (Zip_entry_open ()函数用于打开zip_entry资源并创建可用于提取文件内容的句柄。)

zip_entry_read()

The zip_entry_read() function is used to read the contents of a file in a zip archive. It returns the contents of the file as a string. (Zip_entry_read ()函数用于读取zip存档中文件的内容。它以字符串形式返回文件的内容。)

zip_entry_close()

The zip_entry_close() function is used to close a zip_entry handle. (Zip_entry_close ()函数用于关闭zip_entry句柄。)

zip_close()

The zip_close() function is used to close a zip archive handle. (Zip_close ()函数用于关闭zip存档句柄。)

Example Usage

Example Usage (示例用法)

Let’s take a look at an example of how the PHP zip functions can be used to extract the contents of a zip archive file:

$zip = zip_open('example.zip');

if ($zip) {
   while ($zip_entry = zip_read($zip)) {
       $filename = zip_entry_name($zip_entry);
       $handle = zip_entry_open($zip, $zip_entry);
       $contents = zip_entry_read($zip_entry);
       zip_entry_close($handle);

       // Do something with $filename and $contents
(//使用$ filename和$ contents执行一些操作)
   }

   zip_close($zip);
}

In this example, we first open the zip archive using the zip_open() function. We then loop through each file in the archive using the zip_read() function. For each file, we open a handle using zip_entry_open(), read the contents of the file using zip_entry_read(), and then close the handle using zip_entry_close(). Finally, we close the zip archive handle using zip_close(). (在此示例中,我们首先使用zip_open ()函数打开zip存档。然后,我们使用zip_read ()函数循环浏览存档中的每个文件。对于每个文件,我们使用zip_entry_open ()打开句柄,使用zip_entry_read ()读取文件的内容,然后使用zip_entry_close ()关闭句柄。最后,我们使用zip_close ()关闭zip存档句柄。)

Conclusion

Conclusion (小结)

In this article, we’ve discussed the PHP zip functions and how they can be used to work with zip archives. We’ve explained what zip archives are, and provided examples of how to use some of the most commonly used PHP zip functions to extract the contents of a zip archive file. By using these functions in your PHP applications, you can easily work with zip archives and reduce the size of files for transfer over the internet or storage on disk.
