PHP Debugger::getInstance方法代碼示例

 /**
  * Add an output format or update a format in Debugger.
  *
  * ```
  * Debugger::addFormat('custom', $data);
  * ```
  *
  * Where $data is an array of strings that use Text::insert() variable
  * replacement. The template vars should be in a `{:id}` style.
  * An error formatter can have the following keys:
  *
  * - 'error' - Used for the container for the error message. Gets the following template
  *   variables: `id`, `error`, `code`, `description`, `path`, `line`, `links`, `info`
  * - 'info' - A combination of `code`, `context` and `trace`. Will be set with
  *   the contents of the other template keys.
  * - 'trace' - The container for a stack trace. Gets the following template
  *   variables: `trace`
  * - 'context' - The container element for the context variables.
  *   Gets the following templates: `id`, `context`
  * - 'links' - An array of HTML links that are used for creating links to other resources.
  *   Typically this is used to create javascript links to open other sections.
  *   Link keys, are: `code`, `context`, `help`. See the js output format for an
  *   example.
  * - 'traceLine' - Used for creating lines in the stacktrace. Gets the following
  *   template variables: `reference`, `path`, `line`
  *
  * Alternatively if you want to use a custom callback to do all the formatting, you can use
  * the callback key, and provide a callable:
  *
  * ```
  * Debugger::addFormat('custom', ['callback' => [$foo, 'outputError']];
  * ```
  *
  * The callback can expect two parameters. The first is an array of all
  * the error data. The second contains the formatted strings generated using
  * the other template strings. Keys like `info`, `links`, `code`, `context` and `trace`
  * will be present depending on the other templates in the format type.
  *
  * @param string $format Format to use, including 'js' for JavaScript-enhanced HTML, 'html' for
  *    straight HTML output, or 'txt' for unformatted text.
  * @param array $strings Template strings, or a callback to be used for the output format.
  * @return array The resulting format string set.
