Check query result array's size

Question

With the following code I can iterate through the elements of the returned array:

foreach ($GLOBALS['myDB']->getAssets($i['uId']) as $x)

But I can't figure out how to efficiently check the size of the returned array before entering the loop.

Any ideas?

Answer 1

You can use count to find out the length of an array

count($arrayName);

Answer 2

$assets = $GLOBALS['myDB']->getAssets($i['uId']);
$size = count($assets);
