First, did the original poster realize that he was assigning a value to the
variable $a in the 'if' statement?
Hello,
Yes, I did, and if you read my responses you can see that I came to
the realisations you describe. I don't think that anyone suggested
there was a bug.

Hi John,
I just ran this:
if (($a = foo) || ($b = bar)){
echo $a.br /.$b;
}
and it only spat out foo so I'm guessing things have changed. :)

Hi Tedd,
A little searching enlightened me to the fact that in other languages,
a single | or operator will cancel the short-circuiting so all of
the evaluations are done before proceeding. However, they don't seem
to exist in PHP so in your example it behaves the same as ||...?

From what I understood about || is once it sees a true the whole statement
is regarded as true so nothing else following matters so PHP ignores
everything in the conditional after it evaluates as true...

I received the message below addressed only to me, but I believe the
group could benefit. It looks like the single pipe is a bitwise
operator so you will get an integer as a result (and probably other
weird things to discover when using it on non-numbers).

I am comparing to dates.
define('WSOFFBEGIN','09/16/2012');
$jes = 01/03/2012;
if ( date(m/d/Y, strtotime($jes)) date(m/d/Y, strtotime(WSOFFBEGIN)) )

I cannot figure out why the $error is being assigned inside the if statement,
1/3/2012 is in fact less then 9/16/2012.

Thanks for the reply.
Every example on comparing dates in PHP that I found uses the strtotime
function which I am using. What other type can I use?
When is this example below supposed to work?
// your first date coming from a mysql database (date fields)
$dateA = '2008-03-01 13:34';

Marc,
When you take a date and do a strtotime you are converting it to an int
which you can compare to each other much easier. So for your above example
you would be best doing.
define('WSOFFBEGIN','09/16/2012');
$jes = 01/03/2012;
if ( strtotime($jes) strtotime(WSOFFBEGIN) )
{
$error
Thanks Jonathan. I removed the date() syntax function and it works.

Based on what I learned. I create this simple sample that can occurs
in a real world application.
This simulate a system that needs to send a mail when a flag ($mail)
is true, the system need to
check if the category is passed with the flag to know the type of mail to send.
Here is the results.

You might want to put quotes around that value so it is actually a
string and does not get evaluated.
