For "or" statements it does, but not && or xor. I don't know about you, but I wouldn't want lazy evaluation on a conditional statement involving "and".
The manual ref is http://www.php.ca/manual/en/language.operators.logical.php and the following page on operator precedence.

Hey all, Does PHP support lazy evaluation? Meaning that if: if (isset($HTTP_POST_VARS['submit'])&& $HTTP_POST_VARS['submit'] == 'create')does PHP stop evaluating after the first condition if $HTTP_POST_VARS is not set?
