Note that character variables can be incremented but not decremented and even so only … Read more
array_key_exists will definitely tell you if a key exists in an array, whereas isset will only return true if the key/variable exists and is not null. $a = array(‘key1’ => ‘フーバー’, ‘key2’ => null); isset($a[‘key1’]); // true array_key_exists(‘key1’, $a); // true isset($a[‘key2’]); // false array_key_exists(‘key2′, $a); // true There is another important difference: isset doesn’t … Read more
Your last one was almost there: trait A { function calc($v) { return $v+1; } } class MyClass { use A { calc as protected traitcalc; } function calc($v) { $v++; return $this->traitcalc($v); } } The trait is not a class. You can’t access its members directly. It’s basically just automated copy and paste…
With array_intersect_key and array_flip: var_dump(array_intersect_key($my_array, array_flip($allowed))); array(1) { [“foo”]=> int(1) }
