136 Here's what the surprisingly compact opcodes for the AST above might look like:
148 Finally, the opcodes are read and executed by the interpreter. PHPs uses `three-address code`_ for
155 How exactly each opcode behaves depends on its purpose. You can find a complete list of opcodes in
159 Let's step through the opcodes form the example above:
180 Luckily, it is also not necessary. We can cache the opcodes in memory between requests, to skip over
184 Opcache also performs some optimizations on the opcodes before caching them. As opcaches are
192 takes the virtual PHP opcodes and turns it into actual machine instructions, with additional
