1·It failed because the compreg opcode assumes a hash to initialized.
因为胶压木操作码假定要初始化的哈希值，所以它失败了。
2·We see a much cleaner syntax for defining these functions, which can be optimized for performance by opcode caches.
我们看到了定义这些函数的更规则的语法，这可以通过操作码缓存来优化性能。
3·In contrast, concatenating a string is pretty much just a case of running a single opcode to append a string variable to an existing string variable.
相反，连接字符串操作非常简单，只是运行一个操作码，将一个字符串变量附加到一个现有的字符串变量中即可。
4·In the meantime, investigate one or more of the PHP accelerators and opcode optimizers.
同时，还将研究一个或多个PHP加速器和操作码优化器。
5·Without a doubt, an opcode cache is the first step in speeding up PHP by removing the need to parse and compile a script on every request.
毫无疑问，一个操作码缓存是通过在每次请求后消除解析和编译脚本的需要来加速 PHP 的第一步。
