Get the URL of the Current Page in PHP
In PHP, accessing the URL of the current page is a simple task. This knowledge is particularly useful for tasks such as redirecting users or generating links.
Solution
The $_SERVER superglobal array contains a wealth of information about the current request, including the URL. To retrieve the URL, you can use the following code:
<code class="php">$url = $_SERVER['REQUEST_URI'];</code>
This variable contains the entire URL, including the domain and protocol. If you only need the parts after the domain (e.g., "/example/page.php"), you can use the following:
<code class="php">$url = $_SERVER['REQUEST_URI']; $parts = explode($GLOBALS['HTTP_HOST'], $url); $url = $parts[1];</code>
Query String
If you also require the query string (the portion of the URL that appears after the "?" symbol), you can access it using:
<code class="php">$queryString = $_SERVER['QUERY_STRING'];</code>

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
