Detailed Description

Constructor & Destructor Documentation

Block::__construct ( $options = [] )

Create a new block with specified parameters on a user, IP or IP range.

Parameters

array $options Parameters of the block: address string|User Target user name, User object, IP address or IP range user int Override target user ID (for foreign users) by int User ID of the blocker reason string Reason of the block timestamp string The time at which the block comes into effect auto bool Is this an automatic block? expiry string Timestamp of expiration of the block or 'infinity' anonOnly bool Only disallow anonymous actions createAccount bool Disallow creation of new accounts enableAutoblock bool Enable automatic blocking hideName bool Hide the target user name blockEmail bool Disallow sending emails allowUsertalk bool Allow the target to edit its own talk page byText string Username of the blocker (for foreign users)

Since: 1.26 accepts $options array instead of individual parameters; order of parameters above reflects the original order

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 This should be used when $blocks where retrieved from the user's IP address and $ipChain is populated from the same IP address information.

Parameters

array	$blocks	Array of Block objects
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, ...)

Exceptions

MWException

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

static Block::newFromTarget	(	$specificTarget,

static

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

Parameters

string \| User \| int	$specificTarget	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)
string \| User \| int	$vagueTarget	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!

Parameters

User | string $vagueTarget Also search for blocks affecting this target. Doesn't make any sense to use TYPE_AUTO / TYPE_ID here. Leave blank to skip IP lookups.
