From manual: "Returns false if var exists and has a non-empty, non-zero value, aka falsey, see
conversion to boolean. Otherwise returns true."
Returns FALSE if var exists even with data in it? Does the following prove otherwise or is the error
mine?
<!DOCTYPE html>
<html>
<body>
<?php
$arr = array();$arr[0] = 'fred';
$arr = array();$arr[1] = 'joe';
$arr = array();$arr[2] = 'tom';
$arrB = array();
if (empty($arr)) echo '<br> $arr true'; else echo '<br> else $arr
false';
if (empty($arrB)) echo '<br> $arrB true'; else echo '<br> else $arrB
false';
?>
</body>
</html>
// outputs
// else $arr false
// $arrB true
