Member Function Documentation

static Block::chooseBlock	(	array $	blocks,
		array $	ipChain
	)		`[static]`

From a list of multiple blocks, find the most exact and strongest Block.

The logic for finding the "best" block is:

Blocks that match the block's target IP are preferred over ones in a range
Hardblocks are chosen over softblocks that prevent account creation
Softblocks that prevent account creation are chosen over other softblocks
Other softblocks are chosen over autoblocks
If there are multiple exact or range blocks at the same level, the one chosen is random

Parameters:

Array	$ipChain	list of IPs (strings). This is used to determine how "close" a block is to the server, and if a block matches exactly, or is in a range. The order is furthest from the server to nearest e.g., (Browser, proxy1, proxy2, local-squid, ...)
Array	$block	Array of blocks

Returns:: Block|null the "best" block from the list

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.
