Question

我已经创建了一个register.php文件来注册我正在构建的网站。我正在运行XAMPP来托管我的网站并在我通过付费主机上传之前对其进行测试。在几个视频和在线论坛的帮助下制作了php文件之后，我在google chrome中打开了它，并填写了我创建的注册表单。但是在按下'submit'时会出现以下错误，而不是将用户信息成功写入mysql数据库。

不推荐使用：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为资源，第56行的C：\ xampp \ htdocs \ register.php中给出布尔值

不推荐使用：函数eregi_replace（）在第97行的C：\ xampp \ htdocs \ register.php中已弃用

不推荐使用：函数eregi_replace（）在第98行的C：\ xampp \ htdocs \ register.php中已弃用

不推荐使用：函数eregi_replace（）在第99行的C：\ xampp \ htdocs \ register.php中已弃用

不推荐使用：函数eregi_replace（）在第100行的C：\ xampp \ htdocs \ register.php中已弃用

我知道与eregi_replace()函数相关的错误原因是因为php语言不再支持/使用它。我也知道有preg_replace()的另一种选择但是问题在于，作为php领域的新手，我无法想出一个解决方案。我每天都在学习一点，但我需要快速完成这个页面以继续我的网站和学校我没有时间尝试这么多的多个代码块来提出解决方案。我道歉;我需要一点勺子喂食。：/如果您可以接受我的代码并告诉我如何修复上面列出的错误，甚至更好地回复代码的固定副本，我们将非常感激！感谢您的时间，我再次为我缺乏知识而道歉。

Answer 1

如果您不需要，请不要进行正则表达式。改变

eregi_replace("`", "", $emailCHecker);

到

str_replace("`", "", $emailCHecker);

不要使用mysql_ *函数，因为它们已被弃用。使用mysqli或PDO或任何你喜欢的风格但不再使用mysql_ *！

不鼓励使用此扩展程序。相反，MySQLi或PDO_MySQL 应该使用扩展名。另请参见MySQL：选择API指南和相关常见问题解答了解更多信息。

将'eregi_replace'函数转换为'preg_replace'和'mysql_num_rows'参数修复
