I would understand it if it was like this ..

if (isset($_GET['search'])) { $search = $_GET['search']; }

In the first statement $search would either be set to $_GET['search']
or an empty string, whereas in the second statement $search would only
be set, if there is a $_GET['search']

Wrong. They are equivalent. The second is probably just easier to follow
with a clearly defined default value outside the conditional block.

No, they are not. In the first statement, $search is the value of
$_GET['search'] if the key exists, or an empty string if it does not.
In the second statement, $search is the value of $_GET['search'] if
the key exists or retains its original value if the key does not
exist.

Yes, I didn't realize Yeti had changed the OP's code which convoluted
the issue since his version wasn't what I was responding to and I didn't
realize he dropped a line from the OP's code.

Cheers,
Rob.
