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。

Instructions are aliases-they correspond to the same opcode .

指令是别名，即它们对应于同一操作码。

Unlike APC and Wincache , it is only an opcode cache and optimizer , so it does not contain the user cache components .

不同于APC和Wincache，它仅是一个操作码缓存和优化器，因此它不包含用户缓存组件。

It is generated under a variety of conditions , such as an illegal opcode , illegal operand , privileged opcode , and so on .

它是在特定条件下产生的。例如非法的操作码、非法操作数、特权操作码等等。

php&对PHPV5的APCopcode缓存内的bug的修复

We looked at techniques not only at the PHP level , by leveraging an opcode cache and optimizing the PHP configuration , but also looked at optimizing your database design for proper indexing .

我们不仅通过利用一个操作码缓存和优化PHP配置探究了PHP级别的技术，而且探究了如何优化您的数据库设计来实现合理的索引编制。

An opcode cache and an opcode optimizer , which is often provided in the same package is a dirt-cheap technique to hasten the responsiveness of your site .

操作码缓存以及一个操作码优化器，通常由相同的包提供是一种加快站点响应的低成本技术。

For any website I work with , it 's the one thing I make sure is present , since the performance impact is huge ( many times with response times half of what they are without an opcode cache ) .

对于我使用的任何网站，它是我确保存在的一项内容，因为性能影响很大（很多时候有了操作码缓存，响应时间可减少一半）。

When a PHP script is requested , PHP reads the script and compiles it into what 's called Zend opcode , a binary representation of the code to be executed .

请求一个PHP脚本时，PHP会读取该脚本，并将其编译为Zend操作码，这是要执行的代码的一种二进制表示形式。

Two of the opcode caches we looked at earlier , APC and Wincache , have facilities for doing just this , where you can store PHP data directly into a shared memory segment for quick retrieval .

我们之前探究的两个操作码缓存APC和Wincache具有实现上述操作的工具，其中您可以将PHP数据直接存储到一个共享内存段中，便于快速查询。

One way of debugging this failure is to do an object dump of the executable and save it in a file , then search for the failed instruction ( in this case , the failed opcode is98080000 ) .

调试这个问题的一种方法是对这个可执行程序执行objdump命令，并将其结果保存到一个文件中；然后查找出错的指令（在本例中，出错的操作码是98080000）。
