Unable to update function

function getContactActiveEmails($eid)
{
    global  $db;

    if ($eid) {
        $sql = "SELECT email FROM activeEmails WHERE id = $eid";
        return $db->GetCol($sql);
    }
}

I get the error message "Can not redeclare function getContactActiveEmails"

The line number it gives is the last line of the function - the}

All files are called using require_once. This is the only place in the entire code base where it getContactActiveEmailsis defined. Why is this?

With the error, it is very clear that your function is defined twice, so you get an error.

I would recommend you check if a function is defined before declaring it.

if (!function_exists('getContactActiveEmails'))
{
   function getContactActiveEmails($eid)
   {
      global  $db;

     if ($eid) {
         $sql = "SELECT email FROM activeEmails WHERE id = $eid";
         return $db->GetCol($sql);
     }
   }
}

@Shakti Singh's solution will work, but keep in mind that you are losing control of your code - you don’t know where this function is declared and what it returns, so I suggest looking for it.

  • , IDE , ​​ getcontactactiveemails -.
  • php, - , Reflection extension

:

if(function_exists('getContactActiveEmails')){
    $myfunc = new ReflectionFunction('getContactActiveEmails');
    echo 'Function is declared in '.$myfunc->getFileName().
         ' starting from line '.$myfunc->getStartLine().
         ' to '.$myfunc->getEndLine();
    die;
}

This error occurs if your function is defined in a loop, because you are trying to define it at each iteration.
