如何解决数据库类中的错误计数php

我无法解决此问题，请帮助我。

警告：count（）：参数必须是在第74行的/home/cabox/workspace/Datingmash/app/Class/Database.php中实现Countable的数组或对象

第74行：

public function bind($para, $value)
{   
    $this->parameters[count($this->parameters)] = ":" . $para . "\x7F" . utf8_encode($value);
}

这是数组

array(1) { [0]=> string(29) ":user_api_id1634508113362112" }

完整代码：
