Laravel Sail - SQLSTATE[HY000] [2002] No such file or directory

 Because you are trying to connect to DB container via socket from different container.

There are two separate containers - Laravel and MySQL. Thinks of it like two separate servers.

When you have both unix_socket and db_host in env, you are telling laravel to connect to db at specified host via unix_socket. That is why it didn't work.

When you update the unix_socket env, laravel try to connect to DB via TCP and it work.

P.S: I know this issue is already resolved for you. But in case someone else stumble upon this question, they should have some explanation on why it work and how to fix it in the future.


The error "SQLSTATE[HY000] [2002] No such file or directory" usually occurs when Laravel Sail is unable to connect to the database because the MySQL service is not running or there is a misconfiguration in the database connection settings.

Here are some steps you can follow to troubleshoot this issue:

  1. Check if the MySQL service is running

Make sure that the MySQL service is running on your local machine or within the container. If it is not running, you can start it by running the following command:

sql
sudo service mysql start
  1. Check the database connection settings

Ensure that the database connection settings in the .env file are correct. Check the following variables:

makefile
DB_CONNECTION=mysql 
DB_HOST=mysql 
DB_PORT=3306 
DB_DATABASE=laravel 
DB_USERNAME=sail 
DB_PASSWORD=password

Make sure that the database name, username, and password match the values set in the docker-compose.yml file.

  1. Check if the database container is running

If the MySQL service is running but you still get the error, check if the MySQL container is running by running the following command:

docker-compose ps

If the container is not running, you can start it by running the following command:

docker-compose up -d mysql
  1. Check the MySQL logs

If the above steps do not work, you can check the MySQL logs to see if there are any errors. Run the following command to view the logs:

docker-compose logs mysql

This will display the logs for the MySQL container. Look for any error messages that might be related to the connection issue.

If none of the above steps work, you may need to reinstall Laravel Sail and try again.

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

✔ 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
