PHP remove space from a string

Question

I've this piece of code to rename a file by adding the uploading date, but then I want also to remove all spaces

rename("./uploads/" . "$directory/" . $mvcfile->FileName , "./uploads/" . "$directory/" . $data . "_" . $mvcfile->FileName);

I've tried with

str_replace (" ", "", $mvcfile->FileName);

but it doesn't work.

Any idea of why? I'm pretty new to PHP: what's "->"? Could be this the hitch? Thanks

`->` is the object operator. It denotes an object property or method. In this case, `FileName` is a property of the object instance `$mvcfile`. See [this guide](http://stackoverflow.com/questions/3737139/reference-what-does-this-symbol-mean-in-php) — Michael Berkowski, Mar 07 '12 at 13:29
When are you calling the `str_replace()`? You should call it before `rename()`. Your syntax is correct, and it should work.. — Michael Berkowski, Mar 07 '12 at 13:30

str_replace returns the stripped string - it does not work directly on parameter 3 (since the function signature of str_replace does not list any parameter as a reference)

it works if I first call str_replace and then rename() it. Thanks – Miwi Mar 08 '12 at 14:45

Something like this could work:

$data = time(); // gets the unix timestamp
rename("./uploads/$directory/" . $mvcfile->FileName , "./uploads/$directory/" . $data . "_" . str_replace(" ","",$mvcfile->FileName));

That's assuming what's in $mvcfile->FileName is just the filename, not a path.

It should be :

$mvcfile->FileName=str_replace(" ", "", $mvcfile->FileName);

str_replace() returns a string , so you should initialize your variable to it again
