nikic / PHP-Parser 包的简单实用

解析PHP文件：

<?php

require 'vendor/autoload.php';

use PhpParser\ParserFactory;

$code = file_get_contents(dirname(__FILE__) . '/src/Aop/Target.php');
$phpFactory = new ParserFactory();
$parser = $phpFactory->create(ParserFactory::PREFER_PHP7);
//var_dump($parser->parse($code));die();
foreach ($parser->parse($code) as $k => $v) {
    if ($v instanceof \PhpParser\Node\Stmt\Namespace_) {
        echo 'class namespace: ' . join('\\', $v->name->parts), PHP_EOL;
        foreach ($v->stmts as $kk => $vv) {
            if ($vv instanceof \PhpParser\Node\Stmt\Use_) { //多个use循环
                foreach ($vv->uses as $kkk => $vvv) {
                    echo 'class use: ' . join('\\', $vvv->name->parts), PHP_EOL;
                    echo 'class use alias: ' . $vvv->alias, PHP_EOL;
                }
            } elseif ($vv instanceof \PhpParser\Node\Stmt\Class_) {//类内容
                echo 'class extends: ' . $vv->extends, PHP_EOL;
                echo 'class implements: ' . join(',', $vv->implements), PHP_EOL;
                echo 'class name: ' . $vv->name, PHP_EOL;
                foreach ($vv->stmts as $kkk => $vvv) {//类属性和方法
                    if ($vvv instanceof \PhpParser\Node\Stmt\Property) {//属性
                        foreach ($vvv->props as $kkkk => $vvvv) {
                            echo 'class property name: ' . $vvvv->name, PHP_EOL;
                            echo 'class property value: ' . $vvvv->default->value, PHP_EOL;
                        }
                    } elseif ($vvv instanceof \PhpParser\Node\Stmt\ClassMethod) {//方法
                        echo 'class method name: ' . $vvv->name->name, PHP_EOL;
                        echo 'classs method returnType: ' . $vvv->returnType, PHP_EOL;
                        foreach ($vvv->params as $kkkk => $vvvv) {//方法参数
                            echo 'classs method param name: ' . $vvvv->var->name, PHP_EOL;
                            echo 'classs method param default: ' . $vvvv->default, PHP_EOL;
                        }
                        foreach ($vvv->stmts as $kkkk => $vvvv) {//方法返回
                            echo 'class method return value: ' . $vvvv->expr->value, PHP_EOL;
                        }
                    }
                }
            }
        }
    }
}
