I apologize, my example was too simple and did not reproduce the
problem:

$foo = " ";

$foo = html_entity_decode( $foo, ENT_QUOTES );
$foo = trim( $foo );

echo "x{$foo}x";

output is:  'x x'

Works fine here:
derick@kossu:~$ cat bug31301.php
<?php
$foo = " ";

$foo = trim( $foo );

echo "x{$foo}x";
?>

derick@kossu:~$ php-4.3dev bug31301.php
xx

Description:
------------
When passed a string variable with a single space as its contents,
trim() returns a variable with a single space as its contents.

Reproduce code:
---------------
$foo = " ";

$foo = trim( $foo );

echo "x{$foo}x";

--

output is: 'x x'

Expected result:
----------------
trim() should return a empty string (or false).
