Question

<?php
#require_once( inc/dbc1.php );
$dsn =  mysql:dbname=dbname;host=somehost;
$user =  someuser ;
$password =  SomePass ;

try {
    $dbh = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
    echo  Connection failed:   . $e->getMessage();
}

$pdo1 = new PDO($dsn, $user, $password);
$pdo1->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$sth1 = $pdo1->prepare( SELECT pID, lname, fname FROM Professor ORDER BY pID DESC LIMIT 5; );
$sth1->execute(array());
?>

错误:

Uncaught exception  PDOException  with message  invalid data source name  in  PDO->__construct(  , NULL, NULL) on line 1

任何人都认为这有什么错误?

$dsn =  mysql:dbname=dbname;host=somehost;

maybe just maybe ...

$dsn =  mysql:dbname=dbname;host=somehost ;

除非在截断和解决问题时,这是一纸空文。
