Appending Date/Time to File Upload

How do I add a date and time to the end of my file upload?

Currently I've tried:
move_uploaded_file($_FILES["file"]["tmp_name"],
        "uploads/".$orgid."/".$_FILES["file"]["name"].date("Y-m-d H:i:s"));

Open in new window

This doesn't quite work as it appends like this: filename.jpg2014-01-06 12:01:05

How can I do this so that it will be filename2014-01-06 12:01:05.jpg

1. You shouldn't use a colon in the filename. It's not compatible with every filesystem and can give you headaches later on. Also, if you can, avoid spaces, too. Use underscores and dashes to indicate those types of characters.

2. Without the above corrections, here's what you're likely looking for, but I would highly recommend using my suggestions in #1:

<?php
// Split the original filename by the period character
$pieces = explode(".",$_FILES["file"]["tmp_name"]);

// Grab the last piece, which should be "jpg"
$extension = array_pop($pieces);

// Put the remaining pieces back together with the dot character, add the date, and then add a dot and the extension to get the new filename.
$newfilename = implode(".",$pieces).date("Y-m-d H:i:s").".".$extension;

// Move the file
move_uploaded_file($_FILES["file"]["tmp_name"], "uploads/".$orgid."/".$newfilename);
?>

Underscores work well in file names.  Ascii characters below code point 128 work well in file names, but for readability and common sense, you might want to limit the character set in the file names to alphanumeric + underscore.  Some file systems are not case-sensitive.

A date pattern that you might choose would look like this.  The leading underscore will make it more readable.  date('_Y_m_d_H_i_s');

Ok thanks guys, I'll go with either the . or _.

Don't use the dot!  

Don't use the dot!

Instead use the underscore.  If you want to find out why I recommend against using the dot, try using the dot.  It takes too long to explain, and it will make a mess of your application.  But in life, "understanding" is the bobby prize!

Thanks for using EE, and thanks for the points, ~Ray

Ah gotcha, will stick with underscore then.  Thanks!
