Discuss the case problem of thinkphp6 methods

ThinkPHP is an open source framework based on the PHP language. It is an easy-to-learn, efficient and flexible framework. ThinkPHP has complete functions and easy-to-use interfaces, and its framework design is also well thought out. The sixth version of ThinkPHP (thinkphp6) is optimized and improved on the basis of 5. Today we are going to discuss the issue of method case in thinkphp6.

A method is a set of statement blocks with parameters and return values ​​that are used to perform specific tasks. In general programming languages, method names are case-sensitive, but in ThinkPHP6, you need to pay attention to some details.

The first thing that must be mentioned is the naming convention in ThinkPHP6. The naming convention followed by ThinkPHP6 is PSR-4, which requires class names, interface names, and traits names to be written in the StudlyCaps way (that is, the first letter is capitalized, and the first letter of each word is also capitalized), and the file name is all lowercase.

In ThinkPHP6, method names are case-insensitive. This means that whether you use uppercase, lowercase, or mixed case method names, you can access the method normally. For example, the following code is legal:

public function testMethod() {
    // ...
}

$test->TestMethod();  // 能够正常访问
$test->testmethod();  // 能够正常访问

However, this is only true under PHP 7 or above. In the PHP 5 version, method names are case-sensitive, so you must use the correct naming convention to call methods in a PHP 5 environment.

In addition, in ThinkPHP6, there are also some conventional specifications. Although these specifications do not need to be followed grammatically, these specifications are widely used and following the specifications can improve the readability and maintainability of the code.

1. First of all, methods in the controller (Controller) in ThinkPHP6 usually use camel case naming (CamelCase). For example:

public function index() {
    // ...
}

public function createUser() {
    // ...
}

2. For methods in the model (Model), the underscore naming method (Snake_Case) is usually used. For example:

public function create_user() {
    // ...
}

public function get_user_list() {
    // ...
}

3. Generally, in ThinkPHP6, the method names in the controller are named according to the operations to be performed. For example, if you want to perform a query operation in the controller, you will usually name the method "getXXX", where "XXX" represents the name of the resource to be queried. For example:

public function getUsers() {
    // ...
}

4. In the use of message queue (Queue), method names usually use underscore naming. For example:

protected function fire_job(Job $job, $data) {
    // ...
}

In short, in ThinkPHP6, the case of methods is not sensitive, but adhering to naming conventions and conventional rules can improve the readability and maintainability of the code. Therefore, when writing ThinkPHP6 applications, be sure to follow these specifications.
