有没有人测试过 PHP7 与 Java 8，我想知道它们的性能以及它们的比较。我认为与 Java 8 及其新的垃圾收集器相比，为 PHP 引入的新虚拟机仍然是新的或不成熟的。虽然不确定

Answer 1

比较 PHP 和 Java 是苹果和橘子。很难得到一个公平而有意义的比较。
但是，请参阅 http://benchmarksgame.alioth.debian.org/u64q/compare.php?lang=java&lang2=php .简短的回答是 Java 8 比 PHP 7 快。但是您应该阅读页面上的所有警告......包括语言与语言基准测试非常虚假的事实。
为了记录，这是该页面当前所说的(2017-04-23):
