PHP-函数邮件不'；行不通

我对php函数mail（）有问题。它不发送任何电子邮件：（.我对php完全陌生，通过使用大量教程创建了代码，所以我认为它可能是错的

此外，按钮代码下面的验证也有问题。我想验证用户是否输入了有效的电子邮件，如果没有，则不回显，因为它将显示红色错误

现在，当电子邮件是无效的，它显示“电子邮件发送”的消息，但首先我想电子邮件实际发送

如果没有头文件“From:：”，主机也会阻止SSL协议。它的位置正确吗

据我所知，您在发送邮件时遇到问题，如果没有“From:：”标头，则主机会阻止SSL协议。它的位置是否正确

我有你的邮件不发送和用户邮件验证问题的解决方案。这是我经常用来发送邮件的代码，它工作得非常好

首先启用错误检查并修复任何提到的错误您能告诉我如何做吗？请在谷歌搜索php错误报告我的ftp上有php.ini，设置为：“error\u log=/plik\u logow.log error\u reporting=E\u ALL&~E\u NOTICE log\u errors=1 display\u errors=off”代码，它不会创建任何日志。你是说这个吗？好的，我知道问题出在哪里。我不能修改php.ini文件，如果我不能修改php.ini，我应该如何启用错误检查？谢谢，如果我找不到任何解决方案，我会尝试使用你的代码。尽管我想修复我创建的文件并从中学习一些东西：）
