CHANGELOG
version 1.2
----------------
colorized output in php-cli mode
added default plain text output in php-cli mode

HINTS
$title parameter
--------------
null/false - no title
true - variable type as title
"string" - custom title
$plain parameter
--------------
false - html output (default)
true - plain text output (default in command line mode)
"/path/to/file" - file output by append using plain mode
debug constant
--------------
if defined comma separated list of allowed ip adresses to debug for
!defined('DEBUG') - debug for everyone
const debug = '127.0.0.1,217.07.01.01'; - only clients from this two ips will see debug
if you are logging in error log use to see nicely formated outupt:
tail -f error_log | sed "s/\\\n/\\n/g"
if you want just debug messages nicely formatted:
tail -f error_log | grep --line-buffered "\n--" | sed "s/\\\n/\\n/g"
