I need help getting rid of a fatal error in php [closed]

Hi I'm writing code for a programme that plays blackjack and I keep getting a redeclaration error on a function I'm writing and would like some help

 function displayCard($card)
     {
        $picNum = ( ($card % 5) + 1);
        echo "<img src='images/" . $picNum  . ".png' width='50' height='60' >";

        
         if ($picNum == 1)
             echo "<img src='images/1.png'>";
         elseif ($picNum == 2)
             echo "<img src='images/2.png'>";
         elseif ($picNum == 3)
             echo "<img src='images/3.png'>";    
         elseif ($picNum == 4)

Fatal error: Cannot redeclare displayCard() (previously declared in C:\xampp\htdocs\assignment\blackjack.php:82) in C:\xampp\htdocs\assignment\blackjack.php on line 82

This is the error I keep getting on this part, I'm unsure what the issue might be with it. it is being both declared and redeclared on the same line of code, though I have only entered DisplayCard once I have an earlier function called displayCards which is operating perfectly. I tried changing the displayCard name to displayCardio, but had the same issue.
