Question

当我运行以下PHP代码时：

<?php
$username = "root";
$password = "allen123";
$conn = new PDO('mysql:host=localhost;dbname=test', $username, $password);
?>

我收到以下错误。

致命错误：未使用的异常'PDOException'，消息'SQLSTATE [HY000] [2002]否＆gt;这样的文件或目录'在/Users/idrisk/Colourity/site/index.php:4堆栈跟踪：＃0＆gt ; /Users/idrisk/Colourity/site/index.php(4):PDO-＆gt; __ construct（'mysql：host = loca ...'，'root'，＆gt;'allen123'）＃1 {main}抛出在/Users/idrisk/Colourity/site/index.php第4行

有什么想法吗？我通过Macports下载了PDO驱动程序

修改

To use mysqlnd with a local MySQL server, edit /opt/local/etc/php55/php.ini and set     mysql.default_socket, mysqli.default_socket and pdo_mysql.default_socket to the path
to your MySQL server's socket file.

For mysql5, use /opt/local/var/run/mysql5/mysqld.sock
For mysql51, use /opt/local/var/run/mysql51/mysqld.sock
For mysql55, use /opt/local/var/run/mysql55/mysqld.sock
For mysql56, use /opt/local/var/run/mysql56/mysqld.sock
For mariadb, use /opt/local/var/run/mariadb/mysqld.sock
For percona, use /opt/local/var/run/percona/mysqld.sock

Answer 1

看起来你的php.ini文件中有一个无效的套接字。将pdo_mysql.default_socket设置更改为空字符串以使用默认套接字。

使用PHP获取错误
