$link is of type resource , but the function expects a string .
It seems like the type of the argument is not accepted by the function/method which you are calling. In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug. We suggest to add an explicit type cast like in the following example: function acceptsInteger($int) { }
$x = '123'; // string "123"
// Instead of
acceptsInteger($x);
// we recommend to use
acceptsInteger((integer) $x);

It is not recommended to use PHP's closing tag
?> in files other than templates.
Using a closing tag in PHP files that only contain PHP code is not recommended as you might accidentally add whitespace after the closing tag which would then be output by PHP. This can cause severe problems, for example headers cannot be sent anymore. A simple precaution is to leave off the closing tag as it is not required, and it also has no negative effects whatsoever.
