使用 Symfony VarDumper 替代 var_dump

说明

VarDumper 是一个简单的, 类似于 var_dump 的调试工具, 可以用来替代 var_dump .

安装

composer require symfony/var-dumper

安装完成就可以使用 dump() 函数了.

测试

$a = [
    'ak1' => 'av1',
    'ak2' => 'av2',
    'ak3' => 'av3',
    'ak4' => 'av4',
    'ak5' => 'av5',
];

$b = [
    'bk1' => 'bv1',
    'bk2' => 'bv2',
    'bk3' => 'bv3',
    'bk4' => 'bv4',
    'bk5' => 'bv5',
];

$object = new \stdClass();
$object->prop1 = 10;
$object->prop2 = 20;
$object->prop3 = 30;
$object->prop4 = 40;

$c = [
    'a' => &$a,
    'b' => $b,
    $object
];

dump($c);

效果图:

对类的 Dump

class Test {
    public $prop1 = 10;
    private $prop2 = 20;
    protected $prop3 = 30;
    private $prop4 = 40;

    public function __construct($value) {
        $this->undefinedProp = $value;
    }
}

$t = new Test(50);

dump($t);

效果图

注意看不同类型的类属性的区别.
