Conforme o Core Roundup #9<\/a>, essas s\u00e3o algumas melhorias e RFCs para a vers\u00e3o 8.3, destaques do m\u00eas de Janeiro:<\/p>\n\n\n\n

RFC em vota\u00e7\u00e3o:<\/strong> Readonly amendments<\/a><\/em><\/p>\n\n\n\n

A sugest\u00e3o de mudan\u00e7a \u00e9 para classes normais poderem estender(herdar) de classes Readonly<\/em>(somente leitura). Hoje, \u00e9 proibido e lan\u00e7a um ‘Fatal error<\/em>‘. Tamb\u00e9m, \u00e9 permitir a reinicializa\u00e7\u00e3o de propriedades Readonly <\/em>durante a clonagem.<\/p>\n\n\n\n

RFC implementada:<\/strong> Randomizer Additions<\/a><\/em><\/p>\n\n\n\n

Melhoria na nova extens\u00e3o ‘Random<\/em>‘ do PHP, criada para padronizar a gera\u00e7\u00e3o de n\u00fameros aleat\u00f3rios\/rand\u00f4micos. Esta RFC prop\u00f5e adicionar os m\u00e9todos getBytesFromString()<\/em> e getFloat()\/nextFloat()<\/em>, para gera\u00e7\u00e3o de string e ponto flutuante(float<\/em>) aleat\u00f3rio. Estas opera\u00e7\u00f5es geralmente s\u00e3o aplicadas na userland<\/em>, com uma certa dificuldade.<\/p>\n\n\n\n

RFC em discuss\u00e3o:<\/strong> Path to Saner Increment\/Decrement operators<\/a><\/em><\/p>\n\n\n\n

Altera\u00e7\u00e3o no operador de incremento($v++<\/strong>) e decremento($v–<\/strong>), para padronizar a sa\u00edda quando utilizado com tipo int<\/em> ou float<\/em>. Muitas vezes, a sa\u00edda \u00e9 inesperada.<\/p>\n\n\n\n

A ideia \u00e9 para $v++<\/strong> ser igual $v += 1<\/strong> , e $v– <\/strong>\u00e0 $v -= 1<\/strong>.<\/p>\n\n\n\n

RFC em discuss\u00e3o:<\/strong> Saner array_(sum|product)()<\/a><\/em><\/p>\n\n\n\n

Aqui, \u00e9 para gerar um aviso quando a utiliza\u00e7\u00e3o de array_sum()<\/em> e array_product()<\/em> tiverem um array<\/em> com tipos incompat\u00edveis. Isso ir\u00e1 gerar incompatibilidade com vers\u00f5es anteriores.<\/p>\n\n\n\n

RFC recusada:<\/strong> Asymmetric Visibility<\/a><\/em><\/p>\n\n\n\n

Nesta, teria uma nova sintaxe para declara\u00e7\u00e3o do encapsulamento de propriedades de uma classe, ex:<\/p>\n\n\n\n

class Foo\n{\n  public private(set) string $bar;\n}<\/code><\/pre>\n\n\n\n
No trecho acima, a opera\u00e7\u00e3o getBar()<\/em> seria p\u00fablica, enquanto setBar() <\/em>privada.<\/p>\n\n\n\n
\n\n\n\n
Al\u00e9m destas e outras RFCs, foram implementadas diversas melhorias de desempenho, principalmente nas extens\u00f5es mbstring<\/em> e random<\/em>.<\/p>\n\n\n\n
Pude acompanhar diversos PRs de dezembro de 2022 para c\u00e1 e \u00e9 percept\u00edvel a evolu\u00e7\u00e3o e melhorias que a linguagem vem recebendo, a PHP Foundation<\/a> deu um ‘g\u00e1s’ para a linguagem continuar evoluindo. \ud83d\ude42<\/p>\n\n\n\n
