preg_replace white space

[keak]

Hi there,
I've been trying to replace spaces but I can't see what I'm doing worng. I tried the following and both doesn't seem to be working. Is there a special way of representing white spaces in php?

Many thanks!

preg_replace ('/ /', '', $file_top_formatted);


preg_replace ('/\s/', '', $file_top_formatted);

preg_replace() returns the changed string and leaves the original string alone. I don't see in your two examples where you are accepting the returned changed string:

$somevariable = preg_replace ('/\s/', '', $file_top_formatted);

or even

$file_top_formatted = preg_replace ('/\s/', '', $file_top_formatted);

Why are you using preg-replace to replace empty space.

Try:[blue]str_replace()[/blue]:

http://www.php.net/manual/en/function.str-replace.php

$mystring="This  string  has spac  es";
$output=str_replace(" ","x",$mystring);

//[orange]oupput: Thisxxstringxxhasxspacexxes[/orange]
