symfony - Symfony2, get file type from request -

-

I have a form in my template with a file input.

In my Controller, I can retrieve $ request- & gt; File-> Receive (my file with 'file'); But how can you get the type?

Is there any way with Symphon 2?

get () function FileBag class will throw you if an object is returned lands (or if there is an error.) you can get the mIME type of the file: 

  $ file = $ request- & gt ; File-> File '); $ Type = $ file- & gt; GetMimeType ();

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177
