php file upload type suffix corresponding mine table _php Tutorial

In PHP upload files or images we will encounter to limit the type of upload files, if we only limit the suffix name is very easy to get around the past, I looked for some of the following names corresponding to the mine table, I hope to help you.

When uploading a file using a PHP script, you need to process the file format as a file type known to PHP, for example (. jpg file format image/jpeg). The format of the judgment is first done by the browser, the browser through the submission of the form is a certain type of file, and then submitted to PHP for processing.

Sometimes different browsers do not have the same definitions for file types, so you sometimes need to make judgments about different browsers. In fact, different browser types can be added to the judgment.

Here is a table of file types for IE and Firefox:

Let's look at an example

The code is as follows

Copy Code

$temppath = $upfile [' Tmp_name ']; $fileinfo =pathinfo ($upfile [' name ']); $extension = $upfile [' type ']; Echo $extension; Exit Switch ($extension) { Case ' Application/msword ': $extension = ' Doc '; Break Case ' application/vnd.ms-excel ': $extension = ' xls '; Break Case ' application/vnd.openxmlformats-officedocument.wordprocessingml.document ': $extension = ' docx '; Break Case ' Application/vnd.ms-powerpoint ': $extension = ' ppt '; Break Case ' application/pdf ': $extension = ' pdf '; Break Case ' Application/vnd.openxmlformats-officedocument.spreadsheetml.sheet ': $extension = ' xlsx '; Break Default Die (' Only allow uploading doc,docx,xls,pdf,ppt files to re-upload '); }

The above example limits the only upload doc,docx,xls,pdf,ppt, so that if someone wants to use the suffix name upload other such as PHP or ASP files will be prompted to upload the file is not legal.
