fileupload.php file:

Copy code The code is as follows:

//Determine whether it is an image
switch ($type){
case 'image /pjpeg':$okType=true;
break;
case 'image/jpeg':$okType=true;
break;
case 'image/gif':$okType=true;
break;
case 'image/png ':$okType=true;
break;
}

The above is to determine whether the file is an image type. For more file types, you can refer to the tomcat/conf/web.xml file, which has a complete range of file types. ...

The above has introduced the file upload example code of the file transfer software PHP, including the content of the file transfer software. I hope it will be helpful to friends who are interested in PHP tutorials.
