ECshop 在迁移到 PHP7 时遇到的兼容性问题
在 PHP7 上安装 ECShop V2.7.3时,报错!
Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP; ECS has a deprecated constructor in /usr/local/nginx/html/ecshop/upload/includes/cls_ecshop.php on line 25
这个报错的原因是 PHP7 不再支持与类名相同的构造方法,构造方法统一使用 __construct(), 比如下面的写法 PHP7 就会报这个错误。
<?phpclass foo { function foo() { echo 'I am the constructor'; }}?>
回到 ecshop 我们看一下 cls_ecshop.php 文件的25行。如下
果然有与类名相同的构造方法,我们将构造方法 ECS 修改为 __construct,
回到 ecshop 的安装首页刷新,发现已经没有错误了。
单击下一步,报错
Deprecated: Non-static method cls_image::gd_version() should not be called statically in /usr/local/nginx/html/ecshop/upload/install/includes/lib_installer.php on line 31
这个报错的原因是静态调用非静态方法,比如下面的代码就会报这个错误
<?phpclass foo { function bar() { echo 'I am not static!'; }}foo::bar();?>
修改方法也很简单,要么将该方法改为静态方法,要么将该调用改为非静态调用。
我们看一下报错的文件 lib_installer.php 的 31行代码
还有cls_image类文件的 gd_version() 方法,可以看到的确没有使用 static关键字
第一种修改方式,将该方法修改为静态方法,在方法前加关键字 public static
第二种修改方式,采用非静态方式的调用,修改lib_installer.php 的 31行代码
这两种方法都可以解决问题。
回到ecshop的安装步骤第二页,错误提示已经不见了。
再下一步悲剧了,PHP7 不支持原始的 mysql api 了,PHP7 支持更好的 Mysqli API 和 pdo_mysql api
所以 ecshop 不改掉操作 mysql 的 api 是无法在 PHP7 上运行起来了。

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,

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.

Article discusses essential security features in frameworks to protect against vulnerabilities, including input validation, authentication, and regular updates.

The article discusses adding custom functionality to frameworks, focusing on understanding architecture, identifying extension points, and best practices for integration and debugging.
