确定在php中调用函数的位置

Question

I trying to call my method like this:

<?php getalluser($catid);?>

And there is a select query in my getalluser() method:

function getalluser($query)
{
  $sql = "SELECT * from user where catId='".$query."'";
}

In another page, I call the same method and pass user id instead of category id like so:

<?php getalluser($userID);?>

Now, how i can identify if there is a category id or a user id in $query, so I can change in my where condition base on my $query.

Answer 1

Add another parameter, called from.

Options should be:

Users
Categories

function getalluser($query, $calledFrom = '')
{
  if ($calledFrom == 'users') {
    $sql = "SELECT * from user where catId='".$query."'";
  }
  if ($calledFrom == 'categories') {
   // SQL for fetching categories.
  }
}

And call the function like:

<?php getalluser($catid, 'users');?>
<?php getalluser($catid, 'categories');?>
