5.4.12
的本地主机上正常运行,但是当我将它移动到我的VPS(目前正在托管一个xenforo论坛)时/forums
目录,一旦第一个查询命中,就会杀死页面的其余部分。在我的localhost上,运行查询并显示内容。在VPS上,一旦页面点击查询,它就会停止加载页面的其余部分并将其留空。
这是我的DB.php:
class DB{
private static $_instance = null;
private $_pdo,
$_query,
$_error = false,
$_results,
$_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'));
} catch(PDOException $e){
die($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 $this;
}
public function action($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 $this;
}
}
}
return false;
}
public function get($table, $where){
return $this->action('SELECT *' , $table, $where);
}
public function place($number){
return $this->results()[$number];
}
public function results(){
return $this->_results;
}
public function error(){
return $this->_error;
}
public function count(){
return $this->_count;
}
}
让我疯狂的事情是没有错误!我已经设置error_reporting(E_ALL)
但仍然没有。 VPS上的PHP版本为5.3.3
。如果您需要更多信息,请直接询问,我将对其进行编辑。
