PHP Block::fromMaster方法代码示例

 /**
  * Given a target and the target's type, get an existing Block object if possible.
  * @param 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)
  * @param 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.
  * @param bool $fromMaster Whether to use the DB_MASTER database
  * @return 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!
