Die Ver\u00f6ffentlichung ist f\u00fcr den 21. November geplant. Die wichtigsten neuen Funktionen, die bereits zum Testen verf\u00fcgbar sind oder f\u00fcr die Implementierung in PHP 8.4 geplant sind:  <\/p>\n<ul>\n<li class=\"l\"> Die Unterst\u00fctzung f\u00fcr das Anf\u00fcgen von Property Hooks wurde hinzugef\u00fcgt, die es erm\u00f6glichen, zus\u00e4tzliche Logik hinzuzuf\u00fcgen, die bei \u00c4nderungen oder dem Zugriff auf die Eigenschaften eines Objekts ausgef\u00fchrt wird. Dies geschieht ohne das Abfangen von Lese- und Schreiboperationen mittels der allgemeinen Funktionen __get und __set und ohne zus\u00e4tzliche Wrapper-Methoden zu erstellen. Die Anwendung von Property Hooks erm\u00f6glicht eine erhebliche Reduzierung des Codevolumens und vereinfacht das \u00dcberschreiben des Verhaltens beim Arbeiten mit Eigenschaften, indem ein eigener Handler an jede Eigenschaft gebunden wird.         class User      {         public string $name {             set {                 if (strlen($value) === 0) {                  throw new ValueError('Name muss nicht leer sein');                 }                 $this-&gt;name = $value;             }            }            public function __construct(string $name) {             $this-&gt;name = $name;         }  }\n<li class=\"l\">  Es ist jetzt erlaubt, Verweise auf Methoden in der Konstruktion 'new' ohne trennende Klammern anzugeben, d.h. anstelle von '$name = (new MyClass())-&gt;method()' kann jetzt '$name = new MyClass()-&gt;method()' angegeben werden.\n<li class=\"l\"> Anstelle des allgemeinen Parameters 'opcache.jit_buffer_size' zur Steuerung des JIT-Compilers und zur Einstellung der JIT-Pufferspeichergr\u00f6\u00dfe wurden die Parameter 'opcache.jit' und 'opcache.jit_buffer_size' vorgeschlagen. Um JIT zu deaktivieren, kann jetzt 'opcache.jit=disable' anstelle von 'opcache.jit_buffer_size=0' angegeben werden. Dar\u00fcber hinaus wurden \u00c4nderungen vorgenommen, die den Speicherverbrauch senken und die JIT-Leistung in bestimmten Situationen erh\u00f6hen.\n<li class=\"l\"> Das Verhalten, bei dem f\u00fcr Funktionsparameter mit einem standardm\u00e4\u00dfigen Wert von null automatisch die Zuweisung von null-Werten erlaubt war, wurde als veraltet erkl\u00e4rt. Damit solche Parameter null-Werte annehmen k\u00f6nnen, ist jetzt ein explizites Pr\u00e4fix '?' erforderlich. Beispielsweise sollte anstelle von 'function save(Book $book = null) {}' 'function save(?Book $book = null) {}' angegeben werden.\n<li class=\"l\"> Die Klasse \\\\Dom\\\\HTMLDocument wurde implementiert, die eine korrekte Analyse von HTML5-Markup unterst\u00fctzt.\n<li class=\"l\"> Die Funktion request_parse_body() wurde hinzugef\u00fcgt, um HTTP-Anfragen mit dem Inhaltstyp multipart\/form-data (RFC1867) zu analysieren.    <\/ul>\n<p>Quelle: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=61499\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u0435\u043d \u043f\u0435\u0440\u0432\u044b\u0439 \u0430\u043b\u044c\u0444\u0430-\u0432\u044b\u043f\u0443\u0441\u043a \u043d\u043e\u0432\u043e\u0439 \u0432\u0435\u0442\u043a\u0438 \u044f\u0437\u044b\u043a\u0430 \u043f\u0440\u043e\u0433\u0440\u0430\u043c\u043c\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f PHP 8.4. \u0420\u0435\u043b\u0438\u0437 \u043d\u0430\u043c\u0435\u0447\u0435\u043d \u043d\u0430 21 \u043d\u043e\u044f\u0431\u0440\u044f. \u041e\u0441\u043d\u043e\u0432\u043d\u044b\u0435 \u043d\u043e\u0432\u0448\u0435\u0441\u0442\u0432\u0430, \u0443\u0436\u0435 \u0434\u043e\u0441\u0442\u0443\u043f\u043d\u044b\u0435 \u0434\u043b\u044f \u0442\u0435\u0441\u0442\u0438\u0440\u043e\u0432\u0430\u043d\u0438\u044f \u0438\u043b\u0438 \u043f\u043b\u0430\u043d\u0438\u0440\u0443\u0435\u043c\u044b\u0435 \u043a \u0440\u0435\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0438 \u0432 PHP 8.4: \u0414\u043e\u0431\u0430\u0432\u043b\u0435\u043d\u0430 \u043f\u043e\u0434\u0434\u0435\u0440\u0436\u043a\u0430 \u043f\u0440\u0438\u043a\u0440\u0435\u043f\u043b\u0435\u043d\u0438\u044f \u043e\u0431\u0440\u0430\u0431\u043e\u0442\u0447\u0438\u043a\u043e\u0432 \u0441\u0432\u043e\u0439\u0441\u0442\u0432 (property hook), \u043f\u043e\u0437\u0432\u043e\u043b\u044f\u044e\u0449\u0438\u0445 \u0434\u043e\u0431\u0430\u0432\u0438\u0442\u044c \u0434\u043e\u043f\u043e\u043b\u043d\u0438\u0442\u0435\u043b\u044c\u043d\u0443\u044e \u043b\u043e\u0433\u0438\u043a\u0443, \u0432\u044b\u043f\u043e\u043b\u043d\u044f\u0435\u043c\u0443\u044e \u043f\u0440\u0438 \u0438\u0437\u043c\u0435\u043d\u0435\u043d\u0438\u0438 \u0438\u043b\u0438 \u0434\u043e\u0441\u0442\u0443\u043f\u0435 \u043a \u0441\u0432\u043e\u0439\u0441\u0442\u0432\u0430\u043c \u043e\u0431\u044a\u0435\u043a\u0442\u0430, \u0440\u0435\u0430\u043b\u0438\u0437\u0443\u0435\u043c\u0443\u044e \u0431\u0435\u0437 \u043f\u0435\u0440\u0435\u0445\u0432\u0430\u0442\u0430 \u043e\u043f\u0435\u0440\u0430\u0446\u0438\u0439 \u0447\u0442\u0435\u043d\u0438\u044f \u0438 \u0437\u0430\u043f\u0438\u0441\u0438 \u043f\u0440\u0438 \u043f\u043e\u043c\u043e\u0449\u0438 [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-116995","post","type-post","status-publish","format-standard","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.1.1 -
