I knew that they we're not exactly the same due to order of precedence, but
I ran Robbert's code snippet and found that my assumptions about the outcome
incorrect!
my assumption was that '=' had lower precedence that 'and' ... somehow that
felt right,
obviously I was wrong.
it took me a few seconds to see the error of my ways :-) maybe there are other
that are confused ... maybe the output of following little snippet might help
to clarify:
<?php
$true = true;
$false = false;
$test1 = $true && $false;
$test5 = ($test2 = $true and $false);
$test3 = ($true && $false);
$test4 = ($true and $false);
var_dump($test1, $test2, $test3, $test4, $test5);
?>
thanks to Robbert for the brainteaser ;-)
