我爱编程网小编给大家带来了php如何解压?求简短一点的代码。相关文章，一起来看一下吧。
1. 首先，从 PECL 的 RAR 页面下载 DLL。根据系统情况选择对应版本的 DLL。
2. 下载为 ZIP 包后，解压其中的 php_rar.pdb 和 php_rar.dll 到 PHP 安装目录的 ext 子目录。
3. 在 php.ini 文件中添加扩展引用声明：extension=php_rar.dll。
4. 对于使用 Apache 服务器，需重启 Apache；IIS 下使用 FastCGI 加载的 PHP 则无需额外操作。
5. 解压 RAR 文件，可采用方法一或方法二。
6. 在 Linux 环境中安装 RAR 扩展。先访问 RAR 扩展主页，下载与 PHP 7.2 相匹配的最新版，即 4.0.0。
7. 解压下载的 RAR 扩展文件。
8. 在解压目录中执行 phpize，生成 configure 配置文件。确保执行时使用 --with-php-config 参数，以关联当前 PHP 版本。
9. 运行 configure 命令，生成 RAR 扩展的编译脚本。
10. 编译源码，完成后查看生成的 rar.so 文件路径。
11. 在 php.ini 文件中加入如下配置：最后一行添加 extension=rar.so。
12. 重启相应版本的 PHP7.2 fpm 服务或重启服务器。
13. 检查 PHP 是否成功加载 RAR 扩展，运行相关命令确认。
通过以上步骤，PHP 实现了对 RAR 文件的读取和解压功能。若有更多进阶学习资料需求，包括分布式架构、高可扩展、高性能、高并发等高级进阶干货，可联系获取。
自己记得修改密码。 默认是123456 你可以自己找找里面有没有外连，
搜索http 保证安全。

把中间的代码复制下来，然后用记事本另存为 jieya.php ,
上传到和zip一个目录下，打开这个地址，选择一下，目录记得也要写，
写上密码就按解压就可以了，十分方便简单，

php实现rar文件的读取和解压
实现 PHP 对 RAR 文件的读取和解压，需遵循以下步骤：1. 首先，从 PECL 的 RAR 页面下载 DLL。根据系统情况选择对应版本的 DLL。
2. 下载为 ZIP 包后，解压其中的 php_rar.pdb 和 php_rar.dll 到 PHP 安装目录的 ext 子目录。
3. 在 php.ini 文件中添加扩展引用声明：extension=php_rar.dll。
4. 对于使用 Apache 服务器，需重启 Apache；IIS 下使用 FastCGI 加载的 PHP 则无需额外操作。
5. 解压 RAR 文件，可采用方法一或方法二。
6. 在 Linux 环境中安装 RAR 扩展。先访问 RAR 扩展主页，下载与 PHP 7.2 相匹配的最新版，即 4.0.0。
7. 解压下载的 RAR 扩展文件。
8. 在解压目录中执行 phpize，生成 configure 配置文件。确保执行时使用 --with-php-config 参数，以关联当前 PHP 版本。
9. 运行 configure 命令，生成 RAR 扩展的编译脚本。
10. 编译源码，完成后查看生成的 rar.so 文件路径。
11. 在 php.ini 文件中加入如下配置：最后一行添加 extension=rar.so。
12. 重启相应版本的 PHP7.2 fpm 服务或重启服务器。
13. 检查 PHP 是否成功加载 RAR 扩展，运行相关命令确认。
通过以上步骤，PHP 实现了对 RAR 文件的读取和解压功能。若有更多进阶学习资料需求，包括分布式架构、高可扩展、高性能、高并发等高级进阶干货，可联系获取。
要一个php脚本，能够解压php空间里的zip文件。
呵呵 简单啊 一个文件就可以了。。。自己记得修改密码。 默认是123456 你可以自己找找里面有没有外连，
搜索http 保证安全。

把中间的代码复制下来，然后用记事本另存为 jieya.php ,
上传到和zip一个目录下，打开这个地址，选择一下，目录记得也要写，
写上密码就按解压就可以了，十分方便简单，

php base64 decode 解密（解密PHP混淆代码，求解码(过程)完整方法。。）
php base64 decode 解密PHP中的Base64解密涉及到一系列函数的使用，其中关键的步骤是通过base64_decode函数对加密后的代码进行解密。例如，代码中的connect_sqlmysql($code)函数就是通过解码Base64编码来连接MySQL数据库。另一个例子是met_encode函数，它接受编码后的字符串作为输入，使用base64_encode进行编码处理。
