PHP Dates and If not function not working as is should

[Jam]

Without the boring entry stuff - the function is pretty straight forward. Just don't understand why it ain't working.

$sydatumopteken // this variable I get from the database. The value is 08-10-2020


$sydatumopteken = substr($sydatumopteken,0,2); //the value is 08

$sydatumopteken = (int)$sydatumopteken; //the value is 8

$didagvandag = date("d"); //the value is 08

$didagvandag = (int)$sydatumopteken; //the value is 8

$dag2 = $sydatumopteken + 1; //the value is 9

$dag3 = $sydatumopteken + 2; //the value is 10

$dag4 = $sydatumopteken + 3; //the value is 11

$dag5 = $sydatumopteken + 4; //the value is 12

$dag6 = $sydatumopteken + 5; //the value is 13

  

if($sydatumopteken != $didagvandag || $didagvandag != $dag2 || $didagvandag != $dag3 || $didagvandag != $dag4 || $didagvandag != $dag5 || $didagvandag != $dag6 || $sydatumopteken != 1 || $sydatumopteken != 2 || $sydatumopteken != 3 || $sydatumopteken != 4) {

           Every time it runs, it ends up here. Can someone tell me why.

}

Hi there, Welcome to Code Forum.

Please make sure to add your code using our Code BBCode feature, you can read more here.

Could it be as simple as replacing "||" with "&&"?

Actually, the if has $sysdatumopteken != $dag2 as well as all the following comparisons, which all hold true. This causes the if block to be entered.

Hi Malcolm. Apologies, I am new....and have correct it

Much appreciated! Much easier to read, right?

Not too familiar with this, so an if statement works as if this condition is true. Then do this. So I think that one of your conditions is meeting it's criteria and is displaying the statement.

Thanks for your response!

I am trying to test if the day today ($didagvandag = 08) is the same as the signed up date ($sydatumopteken = 08)
OR
if the day today ($didagvandag = 08) is the same as 5 days after signed up date ($dag2 = $sydatumopteken + 1 = 9, etc.)
OR
if the day today ($didagvandag = 08) is in the first 4 days in the month ($sydatumopteken != 1)

Only one of the above comparisons can be true.
If the day today ($didagvandag) is NOT the same as the signed up date ($sydatumopteken) or 5 days after that or the first four days in the month, then the IF function should be entered.
At the moment - the first statement IS true, and the IF function gets entered.

Definitely easier, thanks!

I want the IF function to enter (work) only if none of the conditions are true. If one of the conditions is true, then the IF function should not enter(work).

Perhaps make sure that in front of each condition you have != (Not) perhaps it's thinking one is not while the other isn't. I could be wrong though.

Many thanks for your responses and advice offered

I actually needed to replace || with && as Krusty the Senile suggested. Everything works smoooothly now.

I was going to suggest working in date objects, so you don't have to worry too much about month boundaries.
Maybe this will help:

$signUpDate = date_create_from_format("d-m-Y", "08-10-2020");
$dateNow = date_create(); // current date/time. Refer to docs if timezone is required.
echo date_format($dateNow, "d-m-Y")."\r\n";
echo date_format($signUpDate, "d-m-Y")."\r\n";
echo date_diff($signUpDate, $dateNow)->days."\r\n";

Wonderful! @Krusty the Senile is amazing at this stuff!
