README
PHP Package for easy logging and error catching. FileLogger class based on Psr/Log helps to filter what to log. ErrorScreen class helps to catch PHP Warnings and Fatal errors and display correct error screen to a user. ApplicationLogger is a trait to include logger in different classes very easy
Installation
Using composer: gelembjuk/logger require: {"gelembjuk/logger": "*"}
Configuration
Configuration is done in run time with a constructor options (as hash argument)
Configure FileLogger
logfile path to your log file (where to write logs)
groupfilter list of groups of events to log. all
means log everything. Groups separated with | symbol
$logger1 = new Gelembjuk\Logger\FileLogger( array( 'logfile' => $logfile, // path to your log file (where to write logs) 'groupfilter' => 'group1|group2|group3' // list of groups of events to log. `all` means log everything ));
Configure ErrorScreen
catchwarnings - (true|false) . If true then user error handler is set to catch warnings
catchfatals - (true|false) . If true then fatal errors are catched. Use to log error and show normal
error screen
catchexceptions - (true|false) . If true then uncatched exceptions will be catched by the object. Use this to catch exceptions missed in any try {} catch block
showwarningmessage - (true|false) . If true then error screen is displayed in case of warning. If is false then error is only logged
showfatalmessage - (true|false) . Display error screen for fatal errors. If false then only log is dine. User will see standard
fatal error in this case
viewformat - set vaue for the viewformat
variable. Possible values: html, json, xml, http . html is default value
showtrace - (true|false). Switcher to know if to show error trace for a user as part of error screen
commonerrormessage - string Common error message to show to a user when error happens
logger - Object of FileLogger class
loggeroptions - Options to create new FileLogger object
$errors = new Gelembjuk\Logger\ErrorScreen( array( 'logger' => $logger1 /*create before*/, 'viewformat' => 'html', 'catchwarnings' => true, 'catchfatals' => true, 'showfatalmessage' => true, 'commonerrormessage' => 'Sorry, somethign went wrong. We will solve ASAP' ) );
Usage
FileLogger
require '../vendor/autoload.php'; $logger1 = new Gelembjuk\Logger\FileLogger( array( 'logfile' => '/tmp/log.txt', 'groupfilter' => 'all' // log everything this time )); // do test log write $logger1->debug('Test log',array('group' => 'test')); $logger1->setGroupFilter('group1|group2'); // after this only group1 and group2 events are logged $logger1->debug('This message will not be in logs as `test` is out of filter',array('group' => 'test'));
ApplicationLogger trait
require '../vendor/autoload.php'; class A { } class B extends A { // include the trait to have logging functionality in this class use Gelembjuk\Logger\ApplicationLogger; public function __construct($logger) { $this->setLogger($logger); $this->logQ('B object create','construct|B'); } public function doSomething() { $this->logQ('doSomething() in B','B'); } } class C { use Gelembjuk\Logger\ApplicationLogger; public function __construct($logger) { $this->setLogger($logger); $this->logQ('C object create','construct|C'); } public function doOtherThing() { $this->logQ('oOtherThing() in C','C'); } } $b = new B($logger1); // $logger1 is instance of FileLogger $c = new C($logger1); $b->doSomething(); $c->doOtherThing();
ErrorScreen
require '../vendor/autoload.php'; $errors = new Gelembjuk\Logger\ErrorScreen( array( 'logger' => $logger1 /*created before*/, 'viewformat' => 'html', 'catchwarnings' => true, 'catchfatals' => true, 'showfatalmessage' => true, 'commonerrormessage' => 'Sorry, somethign went wrong. We will solve ASAP' ) ); // to catch exceptions on the top level of the app try { // do something } catch (Exception $e) { $errors->processError($e); } // presume there was no exception // now catch warning // warning is raised and catched in errors object // error message displayed to a user include('not_existent_file.php');
