正如注释中指出的，确保表单设置了正确的enctype
属性-对于文件上载，它应该是enctype='multipart/form data'

除非您使用move\u uploaded\u file（）
函数，否则在垃圾回收将其删除之前，文件将在tmp
目录中保留一段有限的时间，并且对文件的引用（在数据库中）将不再有效。
处理文件上载时，您应该知道一些基本的事情
1） 例如，您应该在表单中定义加密类型
 <form action="demo_post_enctype.asp" method="post" enctype="multipart/form-data">



2） 接下来，您必须使用move_uploaded_file（源、目标）功能才能上载您的文件
