php-debug

This is the PHP debugger. It's not as good as the other ones out there, but it suited my needs.

What it does

This module can do logging and debugging stuff.

• Log outputs can go to syslog and/or file
• debug outputs can go to cli or JS console ( with auto detect environment)

Also, the dump function provides a prettier version of var_dump, with options for redaction and enable/disable

Debugging Levels

Int	Short Name	long name
0		Reserved
1	ERRR	Error
2	WARN	Warning
3	INFO	Informational
4	VERB	Verbose

Notes

If using a log file output, you should add the logrotate config file to your system

Usage

Include

include '/path/to/debugger/php-debug.php'
$debugSettings = array();
$debug = new debug($debugSettings);

Settings

You can pass an array to set a lot of things

The default values are intended for balance between useful loggin, and security towards web clients

Key		Type	Default	Description
enabled	boolean	true
redact	array		keys that will be searched for in data array and values redacted
logLevel	integer	1	messages of this level or lower will be sent to the log destinations (file and syslog)

syslogName	string	GNU STP	app name registered with syslog
syslogFacility	integer	LOG_LOCAL0	the source registered for syslog
debugLevel	integer	0	this level and lower will be sent to debug destinations (JS console or CLI)
storeMessages	boolean	false	suppress debug output and store messages into a buffer. If not explicitly set, the auto-detect for ajax requests will set this to true
dumpObeysEnabled	boolean	true	if false, dumps will always be outputted. otherwise, it will obey the enabled option
dumpObeysStoreMessages	boolean	true	set whether dumps will be stored in the message buffer according to ['debug']['storeMessages']
