Compatibility issues encountered when migrating ECshop to PHP7 version
Recently, a netizen asked me about an error when installing ecshopv2.7.3 on PHP7. After a long time, I couldn’t find the reason. The editor of Script House will analyze the reasons for this problem.
On PHP7 When installing ECShop V2.7.3, an error message appears!
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
The reason for this error is that PHP7 no longer supports the construction method with the same name as the class. The construction method uniformly uses __construct(), such as the following writing method PHP7 This error will be reported.
<?php class foo { function foo() { echo 'I am the constructor'; } } ?>
Back to ecshop Let’s take a look at line 25 of the cls_ecshop.php file. As follows
Sure enough, there is a constructor with the same name as the class. We changed the constructor method ECS to __construct,
Go back to the ecshop installation homepage and refresh it, and find that there are no errors anymore.

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
The reason for this error is static calling of non-static methods, such as the following The code will report this error
<?php class foo { function bar() { echo 'I am not static!'; } } foo::bar(); ?>
It is also very simple to modify the method, either change the method to a static method, or change the call to a non-static call. Let’s take a look at the 31 lines of code in the file lib_installer.php that reported the error
and the gd version() method of the cls image class file. We can see that it is indeed not used. static keyword
The first modification method is to modify the method to a static method and add the keyword public static
# before the method.

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,

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

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.
