opcode

Looking at what's going on inside PHP recently, I want to know how php generates opcode from a. php file through lexical/grammatical/semantic analysis. Brother Bird in the blog Amway vld.so this php opcode dump tool, the Internet did not install

Brief introductionOpCode is a PHP compiled binary code, the generated opcode as an intermediate language, can help to implement the PHP source code is not open source, of course, this code is also easy to decompile, but for some simple scenes is

The project is a concurrency of tens of thousands, and the data volume reaches tens of millions. the architecture is LNMP, with a redis and opcode. For example, cache (redis), database configuration (MySQL), and server configuration (linux system

In all programming languages, I think strings should be the most common means of expression on Earth.In the Java world, string occurs as a class, and the core of a field is a char array, which is internally exported by maintaining an immutable array

Introduction of APC The alternative PHP cache (APC) is a free and open opcode cache for PHP. Its goal are to provide a free, open, and robust framework for caching and optimizing PHP intermediate code. APC Official website:

JVM opcode loading and storage operation codeload --从局部变量加载值到栈上ldc --从池中加载常量到栈上store --把值从栈中移走，存到局部变量中dup --复制栈顶的值getField --从栈顶对象常量池中得到指定位置的域putField --把值放入对象在常量池中指定位置的域上mathematical Operation opcodeadd --栈顶端的2个值相加，并把结果存在栈中sub

Understanding opcodeOpcode is an intermediate language after PHP script compilation. It is like bytecode of Java or MSL of. net. For example, you wrote the following PHP code:      echo "Hello World";    $a = 1 + 1;    echo $a; ?> PHP
