Today I found a very useful Composer schema package link option named conflict, which is useful when third-party code you rely on is too permissive for your needs. At the time of writing, the conflict man page states Lists packages that conflict with this version of this package. They will…
In Madisoft utilizziamo da sempre le buone pratiche per la gestione delle nostre infrastrutture. Abbiamo sempre pensato che il cloud fosse la scelta giusta per i nostri servizi, ma soprattutto eravamo certi che gestire la nostra infrastruttura come codice, ci avrebbe rallentato leggermente nelle fasi iniziali dei nostri progetti, ma…

That’s tricky! Let’s assume we have two arrays like these:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 |
class Foo { public $bar; public $flag; public function __construct(string $bar, bool $flag) { $this->bar = $bar; $this->flag = $flag; } public function __toString(): string { return $this->bar; } } $array1 = [ new Foo('test', true), ]; $array2 = [ new Foo('test', false), ]; |
Looking at these few lines I would expect that those two arrays are different but if we compare them with php array_diff function they’re the same:
|
1 2 3 4 |
var_dump(array_diff($array1, $array2)); array(0) { } |
This happens because array_diff compares array elements as string so it calls the __toString…
