HTTP/1.x vs. HTTP/2 – The Difference Between the Two Protocols

HTTP (Hypertext Transfer Protocol) is the protocol used by the World Wide Web to transfer data between web servers and clients, such as web browsers. HTTP/1.x and HTTP/2 are two different versions of this protocol. Here are some of the main differences between them:

  1. Performance: HTTP/2 is faster than HTTP/1.x because it supports multiplexing, which allows multiple requests to be sent and received at the same time over a single connection. This reduces the number of connections needed to load a webpage, resulting in faster load times.

  2. Compression: HTTP/2 supports header compression, which reduces the size of the headers sent between the server and the client. This helps to reduce the amount of data that needs to be transferred, resulting in faster load times.

  3. Security: Although both protocols support encryption, HTTP/2 requires it to be enabled by default. This means that all communication between the server and client is encrypted, which improves security.

  4. Server push: HTTP/2 supports server push, which allows the server to send resources to the client before they are requested. This can improve page load times by reducing the number of round-trips needed between the client and server.

  5. Compatibility: HTTP/2 is not compatible with older browsers and servers that only support HTTP/1.x. However, most modern browsers and servers now support HTTP/2.

Overall, HTTP/2 offers significant improvements in performance, security, and efficiency compared to HTTP/1.x. However, the adoption of HTTP/2 is still ongoing, and not all web servers and clients support it.

Remove Unicode Zero Width Space PHP

✔ Recommended Answer This: $newBody = str_replace("​", "", $newBody); presumes the text is HTML entity encoded. This: $newBody = str_replace("\xE2\x80\x8C", "", $newBody); should work if the offending characters are not encoded, but matches the wrong character (0xe2808c). To match the same character as #8203; you need 0xe2808b: $newBody = str_replace("\xE2\x80\x8B", "", $newBody); Source: stackoverflow.com Answered By: Jef Method #2 To remove Unicode zero width space (ZWSP) from a string in PHP, you can use the str_replace() function to replace the ZWSP character with an empty string.

PhpStorm, return value is expected to be 'A', 'object' returned

Image
✔ Recommended Answer Has to be because object can be ANY class instance, even B etc. You can annotate the create() method with generics PHPDoc to tell that the return type will be the same as the input parameter class string. It gives more context info to the IDE. /** * @template T * * @param string $class * @return T */ private function create(string $class) : object { return new $class(); } P.S. Instead of create('B'); better use create(B::class) . This way the IDE can track the usages of that class for refactoring/search purposes etc. Source: stackoverflow.com Answered By: LazyOne Method #2 This error message suggests that your code is expecting a value of type 'A' to be returned, but instead, the code is returning an object. This error can occur in PhpStorm, or any other PHP development environment. To resolve this error, you should check the function or method that is returning the object and ensure that it is returning

Laravel file upload returns forbidden 403, file permission is 700 not 755

✔ Recommended Answer The issue you are facing could be due to incorrect file permissions for the storage folder. Here are some steps to fix the problem: SSH into your cPanel server. Change the permission of the storage folder to 755: chmod -R 755 storage/ This command will change the permission of the storage folder and all its contents to 755, which should give the web server permission to read and write to the folder. Check the ownership of the storage folder. Ensure that the owner of the folder is the same as the user running the web server (typically www-data on Apache): ls -l This command will list the files and folders in the current directory along with their ownership and permission details. Make sure that the owner of the storage folder is the same as the user running the web server. If the ownership is incorrect, you can change it using the following command: chown -R www-data:www-data storage/ This command will change the ownership of the storage folder and all its conten
