I'd be willing to bet it did not; I often use;
if(isset($var) && $var != "") xxxxx second test above would generate error if $var was not valid and the second test was executed anyway. The key is the && between the two tests, first one fails, no need to test the second, probably lifted right out of the C compiler implementation and syntax.

Say you have the following statement, if ( $i == 6 && eregi ( "foo" , $bar ) ) { } And the first portion ( $i == 6 ) IS NOT true, does PHP even attempt to run the regular expression? Just wondering.
