phplog

By Joe Fallon

A simple logging library. It has the following features:

• Full suite of unit tests.
• It can be integrated into any existing project.
• Can be fully understood in just a few moments.
• Each line of log text contains minimal prefix cruft.
• Fully psr/log compliant.

Installation

The easiest way to install PhpDatabase is with Composer. Create the following composer.json file and run the php composer.phar install command to install it.

{
    "require": {
        "joefallon/phplog": "*"
    }
}

Usage

There is one class contained in this library called Log. It contains the following methods:

__construct($filePath, $level)
emergency($message, array $context = array())
alert($message, array $context = array())
critical($message, array $context = array())
error($message, array $context = array())
warning($message, array $context = array())
notice($message, array $context = array())
info($message, array $context = array())
debug($message, array $context = array())
log($level, $message, array $context = array())

Example log entrys with contexts looks like this:

2015-02-05 10:35:20 [DEBUG] Test debug. {"contextKey":"contextVal"}
2015-02-05 10:35:20 [INFO] Test info. {"contextKey":"contextVal"}
2015-02-05 10:35:20 [LOG] Test notice. {"contextKey":"contextVal"}
2015-02-05 10:35:20 [WARN] Test warning. {"contextKey":"contextVal"}
2015-02-05 10:35:20 [ERROR] Test error. {"contextKey":"contextVal"}
2015-02-05 10:35:20 [CRITICAL] Test critical. {"contextKey":"contextVal"}
2015-02-05 10:35:20 [ALERT] Test alert. {"contextKey":"contextVal"}
2015-02-05 10:35:20 [EMERGENCY] Test emergency. {"contextKey":"contextVal"}
2015-02-05 10:35:20 [ALERT] Test off message. {"contextKey":"contextVal"}
