This makes no sense to me, simple comparisons.

[Andreas Paasch]

I'm attempting to trigger things based on time.
I have one shop that has opening hours, closing hours and lunch hours store
as full hour values, integer, in MySQL.
I retrieve them, based on comparisons either shop is open, about to close or
actually closed.
When open, nothing particular is written, when closed, customer is informed
orders can't be executed, shop is closed.
But the last one, right about 15 minutes before closing time, should trigger
a special message to customers, but that comparison just won't work.

[code]
This is what I got:
$closeManTor = (int) $row["closeManTo r"];
$timer = (int) date("H");
$minutter = (int) date("i");

and in a switch statement:
if(($closeManTo r-1) == $timer && $minutter >= 45)
return $almost_closed;
[code]

I tried to modify the last comparing statement to a simpler way,

if($closeManTor == $timer && $minutter >= 0)
return $almost_closed;

but even this fails.

I know for sure that I do compare integers, all have been checked using
gettype(), but that simple if statement just won't trigger anything.
Yes, I have assigned a value to $almost_closed, no problem there.

The switch works fine, as I have another if sentence in the same triggered
statement that works just fine. Connecting these two if-statements with an
if-else-if structure, didn't change anything at all, that's why the first
statement isn't shown here.

I really am getting grey hair here, rather, more then I do have ... and I'm
too young to get all grey haired already now ;-)

I'm sorry, but I really don't understand this one here.

Does your code behave the same way with constants?
[code]
/* ! */ ## changed lines
/* ! */ $closeManTor = 12;
/* ! */ $timer = 11;
/* ! */ $minutter = 53;
[code]

Yes, but

I had another way to check it, and there it works fine, so the problem is
not in this comparison itself, but actually somewhere else.

Your hint about fixing the variables and then running it again, made me
rethink once again and led me to another error that needs to be tracked
down now, thanks for the hint :-)

That's what I figured ...

I never expected it to work with those constants -- though it should :)

Happy bug hunting

try with brackets:

if((($closeManT or-1) == $timer) && ($minutter >= 45))

and try var_dump(($clos eManTor-1) == $timer));
and var_dump(($minu tter >= 45));

before.

Just throwin' this out there, but if your switch statement(s)
evaluate(s) to true, and you're got a "break:" nestled in there, you
might be getting a false positive, and your true positive isn't being
evaluated.

Point being, you might want to juggle the order in which your switch
conditions are evaluated.

Here's kinda what I'm getting at:

In the sample below, you won't ever see the bottom two cases, because
the second case evaluates as a match, and breaks out of the switch
statement.

<?php

$something = 1;
$condOne = "TRUE";

switch($somethi ng){
case 0:
echo "Something is nothing!";
break;
case 1:
echo "Something is 1!";
break;
case 1 && ($condOne=="TRU E"):
echo "Something is 1 and condOne is TRUE!";
break;
case 1 && ($condOne=="FAL SE"):
echo "Something is 1 and condOne is FALSE!";
break;
}

?>
