[SOLVED] Getting substring

[asterixvader]

Hi.

I'd like to know how to get only some parts of the names of files I upload to a page.

(Of course, the files, the upload, etc, don't matter, what matters is the name of the files, which are strings.)

 

All files names are as follow: "img ### comments.ext"

i like to take only the "comments" part, and take out the "img ###" and ".ext" parts.

 

I think it'd work perfectly with the substring function, but the detail is that the quantity of digits in the number part (###) differ from file to file, it's not always 3 digits (also the "comments" part vary).

 

I wondered if there's a way to make Php recognize the position of the second space, after the numbers (since that will always be the initial position, and the final is always -4), but I don't know! You are the Php Freaks.

 

I hope someone will help out!

$fileName = 'img 123 comments.ext';
$comments = preg_replace(array('~^img [0-9]+ ~', '~\.ext$~'), '', $fileName)

 

I think that's right; I'm not the best RegEx'r in the world.

This seems to work perfectly. Thank you!
