PDOException: SQLSTATE[HY000] [2002] No such file or directory

Question

I have put PushChatServer dir in htdocs folder and create database puschat try to run @\"http://localhost/PushChatServer/api/test/database.php\"

Then I got following

Answer 1

I had the same error using PHP 5.6.30 (macOS Sierra) with the simple PDO code like:

$pdo = new PDO('mysql:host=localhost;dbname=db_php', 'root', '');

And I received the same error message. To fix, I changed "localhost" for IP (loopback) "127.0.0.1" in my code:

$pdo = new PDO('mysql:host=127.0.0.1;dbname=db_php', 'root', '');

To test the connection:

$ php -r "new PDO('mysql:host=127.0.0.1;dbname=db_php', 'root', '');"

This work's for me!
