用 google chrome 调试报错代码，如何格式化报错代码？

用的是 symfony 框架，之前用 firebug，更新 firefox 后，firebug 不工作了，换成 google chrome，但是在不能格式化代码，输出数组之类的，全部在一起的。

array:35 [ "block_name" => null "disabled" => false "label" => null "label_format" => null "translation_domain" => null "auto_initialize" => true "trim" => true "required" => true "property_path" => null "mapped" => true "by_reference" => true "inherit_data" => false "compound" => true "method" => "POST" "action" => "" "post_max_size_message" => "The uploaded file was too large. Please try to upload a smaller file." "error_mapping" => [] "invalid_message" => "This value is not valid." "invalid_message_parameters" => [] "allow_extra_fields" => false "extra_fields_message" => "This form should not contain extra fields." "csrf_protection" => true "csrf_field_name" => "_token" "csrf_message" => "The CSRF token is invalid. Please try to resubmit the form." "csrf_token_manager" => CsrfTokenManager {#265 -generator: UriSafeTokenGenerator {#304 -entropy: 256 } -storage: SessionTokenStorage {#267 -session: Session {#18 #storage: NativeSessionStorage {#154 #bags: array:2 [ "attributes" => AttributeBag {#171 -name: "attributes" -storageKey: "_sf2_attributes" #attributes: [] } "flashes" => FlashBag {#173 -name: "flashes" -flashes: []

如何格式化，方便阅读呢？我用的 symfony dump 函数打印的，js 报错也是这样的。
