just do:
if ($something) $this = $that;
...personally I don't like braceless if statements.

or one of these might work for you;
$this = ($something) ? $that: $this; // if $this already exists.
or
$this = ($something) ? $that: null; // if $this does not exist and your happy to use is_null()

btw your not using 'this' as an actual variable name are you?
(unless its on purpose for doing bad(tm) things in php4 :-)

what it does is assign the result of the expression (($something) _or_ $that)
to $this.
if either of those equate to true (dont forget php autotypecasts),
then the expression is true, its a boolean 'or' so it will always make
$this a boolean, which print as:
php -r 'echo true;' // echos 1
php -r 'echo false;' // echos ''
