php - Cannot redeclare the function error

Question

function getContactActiveEmails($eid)
{
    global  $db;

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

I get the error "Cannot redeclare function getContactActiveEmails"

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

All files are being called with require_once. This is the only place in the entire codebase where getContactActiveEmails is being defined. Why is this?

Answer 1

It is very clear from the error your function is defined twice hence you are getting the error.

I would recommend that check if the function is already 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);
     }
   }
}
