如何在IF语句中构建计数器

Question

I'm not sure if this is possible.

I have an IF statement that I am hoping to add a counter to.

Here is my IF statement:

        if ($ageOnDec2016->format('%y') > 12)
        {   
            $ageOnDec2016Display = "<span style='background-color: #FFE4E1'>Aged Out</span>";

        } elseif ($ageOnDec2016->format('%y') == 12) 
        {
            $ageOnDec2016Display= "<span style='background-color: #98FB98'>".$ageOnDec2016->format('%y') ."</span>";
        }
        elseif ($ageOnDec2016->format('%y') == 5) 
        {
            $ageOnDec2016Display= "<span style='background-color: #98FB98'>K Start</span>";
        }
        else
        {               
            $ageOnDec2016Display= $ageOnDec2016->format('%y');
        }

What I am wanting to do is add a counter in the IF statement. If I understand counters correctly, I need to initialize the counter outside the IF Statement, as such:

     $KStart2016=0;

Then, I need to add the counter++ in my if statement. So, like this:

     elseif ($ageOnDec2016->format('%y') == 5) 
        {
            $ageOnDec2016Display= "<span style='background-color: #98FB98'>K Start</span>";
            $KStart2016++;
        } 

Unfortunately, the code is not picking up the counter. It only displays the "0" that I have the counter initialized with.

Any suggestions?

I'm not 100% sure why when I delete the initialization of the counter, that it now works. Wanted to share in case others have this unique problem with counters in an IF statement.

If anyone has any idea on this rationale, please let me know.
