Bitte nutzt kein switch/case mehr in PHP

Bitte nutzt kein switch/case mehr in PHP

Seit PHP 8 gibt es eine typensichere Alternative zu Switch Anweisungen, die sich auch noch leichter schreiben lässt. Wir zeigen euch, wie einfach das ist.

Während die alten Switch-Anweisungen keinen typensicheren Vergleich ermöglichen, fällt vielen die Schreibweise auch immer wieder schwer. Die match() Funktion hilft hier.

Vorher:

switch ($variable) { case 'foo': $newVariable = anyFunctionFoo(); case 'bar': $newVariable = anyFunctionBar(); default: $newVariable = 'foobar'; }

Nachher:

$newVariable = match ($variable) { 'foo' => anyFunctionFoo(), 'bar' => anyFunctionBar(), default => 'foobar', };

Natürlich kann man auf "default" auch verzichten oder mehrere Werte kommasepariert angeben:

$newVariable = match ($variable) { 'foo', 'foobar' => anyFunctionFoo(), 'bar' => anyFunctionBar(), };
