我制作了一个 register.php 文件来注册我目前正在构建的网站。我正在运行 XAMPP 来托管我的网站并在通过付费主机上传之前对其进行测试。在一些视频和在线论坛的帮助下制作了 php 文件后，我在谷歌浏览器中打开了它并填写了我创建的注册表单。但是在按下“提交”时出现以下错误，而不是将用户信息成功写入 mysql 数据库。
已弃用：函数 eregi_replace() 在第 53 行的 C:\xampp\htdocs\register.php 中已弃用
警告：mysql_num_rows() 期望参数 1 是资源，布尔值在第 56 行的 C:\xampp\htdocs\register.php 中给出
已弃用：函数 eregi_replace() 在第 97 行的 C:\xampp\htdocs\register.php 中已弃用
已弃用：函数 eregi_replace() 在第 98 行的 C:\xampp\htdocs\register.php 中已弃用
已弃用：函数 eregi_replace() 在第 99 行的 C:\xampp\htdocs\register.php 中已弃用
已弃用：函数 eregi_replace() 在第 100 行的 C:\xampp\htdocs\register.php 中已弃用
我知道与eregi_replace()函数相关的错误的原因是因为 php 语言不再支持/使用它。我也知道有一个替代方案，preg_replace()但是问题在于，作为 php 领域的新手，我无法提出解决方案。我每天都在学习更多，但我需要快速完成此页面以继续我的网站和学校我没有时间尝试这么多多个代码块来提出解决方案。我道歉; 我需要一点勺子喂食。:/ 如果您能接受我的代码并告诉我如何修复上面列出的错误，或者甚至更好地使用代码的固定副本做出响应，将不胜感激！感谢您的宝贵时间，我再次为我缺乏知识而道歉。
