getting information about the file

[varun aggarwal]

Hi

I have to figure about some information of a file that a user is uploading.
Is there a library or a package that i can use to get some kind of information about the file. I have other options to parse the name of the file and see what type of file it is like .html , .swf etc but it would be nice if i can get some more, like the file size modified date etc with the php library?

Thanks
varun

Hi,

If you are trying to process it as the user uploads it;

using filesize() on your file in upload_tmp_dir will get you the file size, filetime() will get you its modified time (I expect this will be the uploaded time and date).

If you want the info before the user does the upload then you are into client side techniques to get that info..

Also, check out your $_FILES array.

Thanks for the info, $_FILES["filename"]["type"] solved the problem

Hi varun aggarwal,

a word of caution with $_FILES["filename"]["type"], php.net states:

$_FILES['userfile']['type']
 
The mime type of the file, if the browser provided this information. An example would be "image/gif". This mime type is however not checked on the PHP side and therefore don't take its value for granted.

If you read on you will see there is an opportunity (depending what you are doing) to allow malicious code to be executed on your server..

Take a look and apply as required based on your environment.
