Get first element Array in for loop

Question

I am trying to retrieve the last names of the orders placed.

code:

for ($x = 0; $x < 25; ++$x) {

    if (($orders[$x]['paymentStatus'] == 'paid') || ($orders[$x]['paymentIsPost'] == TRUE)) {

        echo '<pre>';
        print_r($orders[$x]['lastname']);
        echo '</pre>';

    }
}

question: code is not showing me the first lastname in the array actually the name that is in position $orders[0]. I thought that pre-incrementing the variable like this ++$x like this would solve the problem. To bad thats not the case. Any tips?

Update output:

[1]""
[2]""
[3]""
[4]""
[5]""

Not sharing lastnames, which is also not relevant.

Can you please provide an example output of var_export($orders);? — VolkerK

then u can try foreach instead of for, with foreach it will guarantee that loop the every element of the array — Santa's helper

try the following to confirm which element of the array you are displaying (and the value of $x

 for($x = 0; $x < 25 ; $x++){
      if(($orders[$x]['paymentStatus'] == 'paid') || ($orders[$x]['paymentIsPost'] == true)){
           echo '<pre>';
           --print_r($orders[$x]['lastname']);
           echo '['.$x.']'.$orders[$x]['lastname'];
           echo '</pre>';
      }
 }

See the opcoming update to the post, it does not display [0] it starts at [1]

See VolkerK's request for an output of $orders just to make sure what data is in there as that could be the source of your problem

do a print_r($orders) prior to the for loop so we can see the data that is in there. I suspect that your 0 element isn't paid or paymentIsPost which is why it isn't displaying, or there isn't a 0 element

your code gave me insight in the solution thank you.

so it was $x++ instead of ++$x or another problem?
