Честита Баба Марта на всички, с пожелания за здраве и щастие :)
В Grabo.bg връзваме мартеници http://grabo.bg/martenici ... виртуални :)

От Windows NT 4.0 насам има една програмка с помощта на която може да се прави бърз backup на данните (mirror). Като едно от предимствата е че използва няколко Threads и благодарение на това копирането става една идея по-бързо от стандартното copy / paste през explorer-a.
Примерно ако искаме да направим копие на файловете от

 D:\Archive 

към

F:\Archive

използвайки 10 thread-s бихме могли да използваме следната команда

 robocopy D:\Archive  F:\Archive /MT:10 /MIR 

резултата при мен беше:

като за обик. копиране според ОС биха били нужни поне 1 час.
ps: забравих да спомена че програмката е конзолна и се стартира през cmd promt ( windows+r пишем cmd :D )
документацията може да се види през

 robocopy /? 

Една малка функция която форматира телефонен номер към формат: 1234 345 789

function formatPhoneNumber($phone) {
		return preg_replace("/([0-9]{4})([0-9]{3})([0-9]{2,})/", "$1 $2 $3", preg_replace("/[^0-9]/", "", $phone));
	}
