Problem with if statement and match with specific categories

Question

I have a problem with an if statement

I want to display a different button for elements that are assigned to a specific category (7) than for elements that do not belong to that category:

<?php
            $result=get_media($ref);
            if(empty($result))

                include ('button1.php');

            if (count($result)>0)
            {

                for ($n = 0; $n < count($result); $n++)
                {

                    if($result[$n]["ref"] == '7')
                    {
                        include ('button2.php');
                    }
                    else 
                        include ('button1.php');
                }
            }
            ?>

The if statement works if the element is assigned to category "7" only. But if it is assigned to other categories as well, the "else" command is not working and both buttons are shown.

I could of course add more category IDs to the if statement but this would be a lot of them.

Also an unequal command in the else statement does not work.

With $result I get the value (ID) of the category to which the called element was assigned. But the element can be in an infinite number of categories. — p.dahl, May 28 '20 at 15:57

Since 7 is your only trigger, let's simplify things a bit.

<?php
            $result = get_media($ref);
            $button = 'button1.php';
            $count  = count($result);

            if ($count > 0) {
               for ($n = 0; $n < $count; $n++) {
                  if($result[$n]["ref"] == '7') {
                        $button = 'button2.php';
                   }
               }
            }
            include ($button);
            ?>

Or use an array function. Not sure which one is faster.

<?php
            $result = get_media($ref);
            $button = 'button1.php';
            $count  = count($result);

            if ($count > 0) {
                  if(in_array(7, array_column($result, 'ref'))) {
                        $button = 'button2.php';
                  }
            }
            include ($button);
            ?>

I tried the first solution and it worked. It's perfect. If the second one is faster, how could I test it? I'd rate the answer as useful, but I still don't have enough reputation. Later, then. — p.dahl, May 28 '20 at 16:12
take a look at the microtime function. Or this post https://stackoverflow.com/questions/1200214/how-can-i-measure-the-speed-of-code-written-in-php — RST, May 28 '20 at 16:16
