我有一个用php编写的示例图像上传代码。ios开发人员调用web服务。文件上传在一台服务器上运行良好，但在另一台服务器上传失败。
检查了权限、目录列表等。在尝试上传图像时，服务器抛出了500个内部错误。
我认为.htaccess 可能有问题
有人能指导我编辑htaccess，使其支持图像上传吗。
谢谢。通过浏览器上传时，文件上传工作正常。它没有返回任何错误
这是错误日志PHP警告：fopen（xml/）[function.fopen]：无法打开流：在第271行的/home/appsimon/public_html/api/import.PHP中没有这样的文件或目录
事实上，直到上周它还在这个服务器上工作。突然文件上传失败
htaccess 中的代码
#old php Handler
#deny from all
#allow from ip address
只有这3行评论来自应用控制台的错误

在htaccess中尝试添加这些值，看看会发生什么
php_value upload_max_filesize 100M
php_value post_max_size 100M
php_value max_execution_time 180
php_value max_input_time 180
根据需要调整值
