Php uploads Excle files

Php uploads Excle files in PHP Excel

To upload an EXCEL file in php, only the EXCEL file is displayed when you select a file, and how to determine $ upfile =$ _ FILES ["upfile"]; $ type = $ upfile ["type"]; $ type is excel. I tried $ type = "xls". what should it be like, another problem is that during the upload, not all files are first uploaded to a temporary file and then moved to the specified target. how can this temporary file be deleted?

1. $ upfile ["type"]:

Xla application/vnd. ms-excel
Xlc application/vnd. ms-excel
Xll application/x-excel
Xlm application/vnd. ms-excel
Xls application/vnd. ms-excel
Xlt application/vnd. ms-excel
Xlw application/vnd. ms-excel

2. you do not need to worry about the temporary directory. after the upload program is executed, the system will automatically delete the temporary files.

1. $ upfile ["type"]:

Xla application/vnd. ms-excel
Xlc application/vnd. ms-excel
Xll application/x-excel
Xlm application/vnd. ms-excel
Xls application/vnd. ms-excel
Xlt application/vnd. ms-excel
Xlw application/vnd. ms-excel

Are these in excle format, as long as $ type = "application/vnd. ms-excel "?

I wrote this?
Witch ($ type ){
Case 'xla application/vnd. ms-excel ': $ OK = 1;
Break;
Case 'xlc application/vnd. ms-excel ': $ OK = 1;
Break;
Case 'xll application/x-excel ': $ OK = 1;
Break;
Case 'xlm application/vnd. ms-exce ': $ OK = 1;
Break;
Case 'XLS application/vnd. ms-excel ': $ OK = 1;
Break;
Case 'xlt application/vnd. ms-excel ': $ OK = 1;
Break;
Case 'xlw application/vnd. ms-excel ': $ OK = 1;
Break;

}
