static Block::newFromTarget	(	$	specificTarget,

Given a target and the target's type, get an existing Block object if possible.

Parameters:

	$specificTarget	String\|User\|Int a block target, which may be one of several types: * A user to block, in which case $target will be a User * An IP to block, in which case $target will be a User generated by using User::newFromName( $ip, false ) to turn off name validation * An IP range, in which case $target will be a String "123.123.123.123/18" etc * The ID of an existing block, in the format "#12345" (since pure numbers are valid usernames Calling this with a user, IP address or range will not select autoblocks, and will only select a block where the targets match exactly (so looking for blocks on 1.2.3.4 will not select 1.2.0.0/16 or even 1.2.3.4/32)
	$vagueTarget	String\|User\|Int as above, but we will search for any block which affects that target (so for an IP address, get ranges containing that IP; and also get any relevant autoblocks). Leave empty or blank to skip IP-based lookups.
bool	$fromMaster	whether to use the DB_MASTER database

Returns:: Block|null (null if no relevant block could be found). The target and type of the returned Block will refer to the actual block which was found, which might not be the same as the target you gave if you used $vagueTarget!
