 ### Quick Usage Example (with Charge Credit Card - Authorize and Capture)
 Note: The following is a php console application. Ensure that you can invoke the php command from command line.
 - Save the below code to a php file named, say, `charge-credit-card.php`
-- Open command prompt and navigate to your sdk folder ( if want to run from a different folder, modify the `require` statement to have the full path to the sdk e.g. `require 'c:/anet-sdk-php/vendor/autoload.php'` in place of `require 'vendor/autoload.php'` )

 - Update dependecies - e.g., With composer, type `composer update`

+The SDK generates a log with masking for sensitive data like credit card, expiration dates. The provided levels for logging are 
  `debug`, `info`, `warn`, `error`. Add ````use \net\authorize\util\LogFactory;````. Logger can be initialized using `$logger = LogFactory::getLog(get_class($this));`
 The default log file `phplog` gets generated in the current folder. The subsequent logs are appended to the same file, unless the execution folder is changed, and a new log file is generated.

 ### Customizing Sensitive Tags
-A local copy of [AuthorizedNetSensitiveTagsConfig.json](/lib/net/authorize/util/ANetSensitiveFields.php) gets generated when code invoking the logger first gets executed. The local file can later be edited by developer to re-configure what is masked and what is visible. (*Do not edit the json in sdk*).

 - For each element of the `sensitiveTags` array, 
   - `tagName` field corresponds to the name of the property in object, or xml-tag that should be hidden entirely ( *XXXX* shown if no replacement specified ) or masked (e.g. showing the last 4 digits of credit card number).
   - `pattern`[<sup>[Note]</sup>](#regex-note) and `replacement`[<sup>[Note]</sup>](#regex-note) can be left `""`, if the default is to be used (as defined in [Log.php](/lib/net/authorize/util/Log.php)). `pattern` gives the regex to identify, while `replacement` defines the visible part.
