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。

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 .

因此当PHP脚本的缓存操作码存在时，我们可以跳过PHP请求流程的解析和编译步骤，直接执行缓存操作码并输出结果。

So when the cached opcodes of a PHP script exists , we can skip by the parse and compile steps of the PHP request process and directly execute the cache opcodes and output the results .
