<?php

$host='localhost';
$db='canda';
$user='root';
$pass='123456789';

try{
    new PDO("mysql:host=".$host
                ."; dbname=".$db,
                $user, $pass);
}catch (PDOException $e) {
    echo $e;
}

PDOException：SQLSTATE [HY000] [2002] /Users/mac/Desktop/test.php:11中没有这样的文件或目录：堆栈跟踪：＃0 /Users/mac/Desktop/test.php(11）：PDO -> __ construct（'mysql：host = loca ...'，'root'，'password'）＃1 {main}

那里有更清洁的版本；

 $host      = DB_HOST; // just ignore constants //
 $user      = DB_USER;
 $pass      = DB_PASS;
 $dbname    = DB_NAME;

   $dsn = 'mysql:host=' . $host . ';dbname=' . $dbname;
    // Set options
    $options = array(
        PDO::ATTR_PERSISTENT    => true,
        PDO::ATTR_ERRMODE       => PDO::ERRMODE_EXCEPTION
    );
    // Create a new PDO instanace
    try{
         new PDO($dsn, $user, $pass, $options);
    }
    // Catch any errors
    catch(PDOException $e){
        echo $e;
    }

如果这行不通，那么您去pdoexception-sqlstatehy000-2002-no-such-file-or-directory
