Logging

// FastSitePHP includes two logging classes that implement the widely used
// [Psr\Log] Interface.

// Create a file logger. Log messages are appended and the file is created
// the when the first message is added.
$file = __DIR__ . '/log.txt';
$file_logger = new \FastSitePHP\Data\Log\FileLogger($file);

// Create an HTML Logger
// This class can be used for temporary development logs because it outputs an
// HTML table of logged messages after the response is sent or depending on
// options can be used to replace the original response. The parameter
// [$replace_response] is optional.
$replace_response = false;
$html_logger = new \FastSitePHP\Data\Log\HtmlLogger($app, $replace_response);

// Log messages using one of the following functions:
//     emergency(), alert(), critical(), error(),
//     warning(), notice(), info(), debug()
$file_logger->info('This is a Test.');
$html_logger->error('Application Test');

// Additionally data can be passed to the message with placeholders
$html_logger->info('User {name} created', [
    'name' => 'Admin'
]);

// The date format can be any valid value for the PHP function [date()].
// Default is [\DateTime::ISO8601].
$file_logger->date_format = 'Y-m-d H:i:s';

// For the file logger the output format can be controlled by properties.
//
// Default Format:
//     '{date} {level} - {message}{line_break}';
//
// Line Breaks default based on the OS:
//     "\r\n" - Windows
//     "\n"   - Other OS's
$file_logger->log_format = '[{level}] {message}{line_break}';
$file_logger->line_break = '^^';

// You can also customize the HTML Logger with your own template:
// $html_logger->temlate_file = 'YOUR_TEMPLATE.php';

Class Constructor

The FastSitePHP Application must be passed when this class is created. Once called it adds either a [beforeSend()] or [after()] event based on the optional parameter [$replace_response].
