son9ne's note below isn't entirely accurate, consider the following code:
$test = '';
function func($var) { return $var; }
function func2($var) {
switch ($var) {
case is_string($var): return $var;
case is_array($var): return $var;
}
}
function func3($var) {
switch ($var) {
case is_string($var): print "string!"; break;
case is_array($var): print "array!"; break;
}
}
if (is_array($test)): print "array!"; elseif (is_string($test)): print
"string!"; endif;
if (is_array(func($test))): print "array!"; elseif (is_string(func($test))): print
"string!"; endif;
if (is_array(func2($test))): print "array!"; elseif (is_string(func2($test))): print
"string!"; endif;
func3($test);
It will output: string! string! string! array!
I would expect the output: string! string! string! string!
I think this is a bug in PHP's switch statement.
