提示这个错误 哪里不对了？
( ! ) Parse error: syntax error, unexpected '->' (T_OBJECT_OPERATOR), expecting ')' in D:\wamp\www\prepare.php on line 4
代码如下
$pdo=new PDO("mysql:host=localhost;dbname=t1","root","");
$stnt=$pdo->prepare("insert into blog2 (type,name,num,content)values(:type,:name,:num,:content) ");
$stnt->execute(array("type"->"5","name"->"5","num"->"5","content"->"5"));
?>
$stnt->execute(array(":type"=>"5",":name"=>"5",":num"=>"5",":content"=>"5"));
$stnt->execute(array(":type"=>"5",":name"=>"5",":num"=>"5",":content"=>"5"));
