Php 条令未捕获例外'；反射异常'；带有消息'；XXX类不存在'；

我正在尝试在mysql数据库中插入。我使用的是条令和标准PHP（无框架）。我有3个表和它们的3个PHP类

<?php

namespace model\dto;

use Doctrine\ORM\Mapping as ORM;

/**
 * Canales
 *
 * @ORM\Table(name="Canales")
 * @ORM\Entity
 */
class Canales
{

/**

 *
 * @ORM\Column(name="Nombre", type="string", length=255, nullable=false)
 */
private $nombre;

/**

 */
private $url;

/**

 */
private $imagen;

/**

 */
private $ingles;

/**

private $id;

...
}

<?php

<?php

use Doctrine\ORM\Mapping as ORM;

private $idYoutube;

private $titulo;

/**

...
}

关于这个错误有什么想法或建议吗

提前感谢

我找到了解决方案。在我的班上，塞特卡纳尔是这样的

公共函数setIdcanal（Canales$idcanal=null）{
...
}

我必须为此更改它：

public function setIdcanal(\model\dto\Canales $idcanal = null) { 
...
}

我找到了解决办法。在我的课堂上，setCanal类似于公共函数setIdcanal（Canales$idcanal=null）。我必须对此进行更改：公共函数setIdcanal（\model\dto\Canales$idcanal=null）

<?php
function getPlaylists($idCanal) {

    $key = 'XXXX';
    $channel = $idCanal; //ejemplo: UCL-aihy3UD61TmvCOL9szUw

    $url = "https://www.googleapis.com/youtube/v3/playlists?key=$key&channelId=$channel&part=snippet,id&order=date&maxResults=50";

    $json = file_get_contents($url);

    $obj = json_decode($json, true);

    //var_dump($obj);

    return $obj;
}

function getVideosByPlaylists($idPlaylist) {

    $key = 'XXXXX';

    $url = "https://www.googleapis.com/youtube/v3/playlistItems?key=$key&playlistId=$idPlaylist&part=snippet,id&order=date&maxResults=50";

    $json = file_get_contents($url);

    $obj = json_decode($json, true);

    //var_dump($obj);

    return $obj;
}
