BUG记录2
[问题] 参数不符合
[问题描述]

参数要求是数组,实际却是字符串implode(): Argument #1 ($pieces) must be of type array, string given in implode()// 出错前代码$variables['classes'] = implode(' ', $variables['classes_array']);// 修改方法if(is_array($variables['classes_array'])){$variables['classes'] = implode(' ', $variables['classes_array']);}else if (is_string($variables['classes_array'])){$variables['classes'] = implode(' ', (array)$variables['classes_array']);// 等价于$variables['classes'] = explode(' ', $variables['classes_array']);}

[解决方法] 运行前判断参数类型
