你好，我有登錄該代碼和PHP註冊OOPOOP對象
<?php
class DB {
public static $instance = null;
private $_pdo = null,
$_query = null,
$_error = false,
$_results = null,
$_count = 0;
private function __construct() {
try {
$this->_pdo = new PDO('mysql:host=' . Config::get('mysql/host') . ';dbname=' . Config::get('mysql/db'), Config::get('mysql/username'), Config::get('mysql/password'), array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
//$this->query('SET NAMES utf8');
} catch(PDOExeption $e) {
die($e->getMessage());
}
}
public static function getInstance() {
if(!isset(self::$instance)) {
self::$instance = new DB();
}
return self::$instance;
}
public function query($sql, $params = array()) {
$this->_error = false;
if($this->_query = $this->_pdo->prepare($sql)) {
$x = 1;
if(count($params)) {
foreach($params as $param) {
$this->_query->bindValue($x, $param);
$x++;
}
}
if($this->_query->execute()) {
$this->_results = $this->_query->fetchAll(PDO::FETCH_OBJ);
$this->_count = $this->_query->rowCount();
} else {
$this->_error = true;
}
}
return $this;
}
public function get($table, $where) {
return $this->action('SELECT *', $table, $where);
}
public function delete($table, $where) {
return $this->action('DELETE', $table, $where);
}
public function action($action, $table, $where = array()) {
if(count($where) === 3) {
$operators = array('=', '>', '<', '>=', '<=');
$field = $where[0];
$operator = $where[1];
$value = $where[2];
if(in_array($operator, $operators)) {
$sql = "{$action} FROM {$table} WHERE {$field} {$operator} ?";
if(!$this->query($sql, array($value))->error()) {
return $this;
}
}
return false;
}
}
public function insert($table, $fields = array()) {
$keys = array_keys($fields);
$values = null;
$x = 1;
foreach($fields as $value) {
$values .= "?";
if($x < count($fields)) {
$values .= ', ';
}
$x++;
}
$sql = "INSERT INTO {$table} (`" . implode('`, `', $keys) . "`) VALUES ({$values})";
if(!$this->query($sql, $fields)->error()) {
return true;
}
return false;
}
public function update($table, $id, $fields = array()) {
$set = null;
$x = 1;
foreach($fields as $name => $value) {
$set .= "{$name} = ?";
if($x < count($fields)) {
$set .= ', ';
}
$x++;
}
$sql = "UPDATE {$table} SET {$set} WHERE id = {$id}";
if(!$this->query($sql, $fields)->error()) {
return true;
}
return false;
}
public function results() {
// Return result object
return $this->_results;
}
public function first() {
return $this->_results[0];
}
public function count() {
// Return count
return $this->_count;
}
public function error() {
return $this->_error;
}
public function lastInsertId(){
return $this->_pdo->lastInsertId();
}
public function __sleep(){
return array();
}
}
和我保存會話的用戶登錄數據，一切都在本地主機工作正常，但在我的Web服務器，我有在該行的一個問題$this->_query->bindValue($x, $param);
Catchable fatal error: Object of class __PHP_Incomplete_Class could not be converted to string in
我知道這是錯誤的東西與我的會議，但我找不到什麼問題，這是我的會話類
<?php
class Session {
public static function exists($name) {
return (isset($_SESSION[$name])) ? true : false;
}
public static function get($name) {
return $_SESSION[$name];
}
public static function put($name, $value) {
return $_SESSION[$name] = $value;
}
public static function delete($name) {
if(self::exists($name)) {
unset($_SESSION[$name]);
}
}
public static function flash($name, $string = null) {
if(self::exists($name)) {
$session = self::get($name);
self::delete($name);
return $session;
} else if ($string) {
self::put($name, $string);
}
}
}
請告訴我，如果你能我能做什麼，那個錯誤非常感謝你。
而這正是我存儲我的會議
public function login($username = null, $password = null, $remember = false) {
if(!$username && !$password && $this->exists()) {
Session::put($this->_sessionName, $this->data()->id);
} else {
$user = $this->find($username);
if($user) {
if($this->data()->password === Hash::make($password, $this->data()->salt)) {
Session::put($this->_sessionName, $this->data()->id);
if($remember) {
$hash = Hash::unique();
$hashCheck = $this->_db->get(Config::get('mysql/tbl_user_sessions'), array('user_id', '=', $this->data()->id));
if(!$hashCheck->count()) {
$this->_db->insert(Config::get('mysql/tbl_user_sessions'), array(
'user_id' => $this->data()->id,
'hash' => $hash
));
} else {
$hash = $hashCheck->first()->hash;
}
Cookie::put($this->_cookieName, $hash, Config::get('remember/cookie_expiry'));
}
return true;
}
}
}
return false;
}
我只是做的var_dump代碼我session['user']
array(1) {
["user"]=> &object(__PHP_Incomplete_Class)#1 (6) {
["__PHP_Incomplete_Class_Name"]=> string(4) "User"
["_db":"User":private]=> object(__PHP_Incomplete_Class)#2 (1) {
["__PHP_Incomplete_Class_Name"]=> string(2) "DB"
}
["_sessionName":"User":private]=> string(4) "user"
["_cookieName":"User":private]=> string(4) "hash"
["_data":"User":private]=> object(stdClass)#3 (7) {
["id"]=> string(3) "144"
["username"]=> string(5) "admin"
["password"]=> string(64) "0611affa6664e471b939cd3197b49e0c3b47d146fc12a472c4275dbd85a7cd67"
["salt"]=> string(32) "458a0dbfbd9bdca381e50b8d753329ea"

["joined"]=> string(19) "2013-11-29 07:41:54"
["group"]=> string(1) "1"
}
["_isLoggedIn":"User":private]=> bool(true)
}
}
發佈完整的錯誤消息，因爲您在位置之前將其關閉。另外，請參考您問題中的行號。 – Daniel

可捕獲的致命錯誤：類__PHP_Incomplete_Class的對象無法轉換爲第38行中的oop/classes/DB.php中的字符串，並且第38行是此行$ this - > _ query-> bindValue（$ x，$ param）; – Arturik1988
