我一直在试图解决这个问题，并且一直在搜索 Stackoverflow 和其他网站以查找与我的问题相关的任何内容。
我有一个 php 脚本，当人们打开相应的页面时，它正在更新一个 mysql 表。整个事情工作正常（因为我一直让它在每一步都打印文本以验证数据是否存在。如果从未访问过页面或更新total_votes 和 current_vote 每次访问。total_votes 用于在不同页面上使用的统计报告。current_vote 的值每周都会减少。
出于某种原因，我收到了警告。我认为尽管整个工作正常，但最好还是问一下，因为我讨厌我无法解决的警告和错误（即使最终结果没有问题。
数据库设置为 utf8_general_ci，因此 url 信息不应该成为问题。
