Method Detail

__construct (Constructor)   [line 265]

Net_DNS2 __construct( [array $options = null])

Constructor - base constructor for the Resolver and Updater
  • Throws: Net_DNS2_Exception
  • Access: public

Overridden in child classes as:

Net_DNS2_Updater::__construct()
Constructor - builds a new Net_DNS2_Updater objected used for doing dynamic DNS updates
Net_DNS2_Resolver::__construct()
Constructor - creates a new Net_DNS2_Resolver object

Parameters:

mixed   $options   —  array of options or null for none

[ Top ]

autoload   [line 342]

void autoload( string $name)

autoload call-back function; used to auto-load classes
  • Access: public

Parameters:

string   $name   —  the name of the class

[ Top ]

cacheable   [line 674]

bool cacheable( stream $_type)

a simple function to determine if the RR type is cacheable
  • Return: returns true/false if the RR type if cachable
  • Access: public

Parameters:

stream   $_type   —  the RR type string

[ Top ]

checkServers   [line 503]

boolean checkServers( [mixed $default = null])

checks the list of name servers to make sure they're set
  • Throws: Net_DNS2_Exception
  • Access: protected

Parameters:

mixed   $default   —  a path to a resolv.conf file or an array of servers.

[ Top ]

expandIPv6   [line 798]

string expandIPv6( string $_address)

formats the given IPv6 address as a fully expanded IPv6 address
  • Return: the fully expanded IPv6 address
  • Access: public

Parameters:

string   $_address   —  the IPv6 address to expand

[ Top ]

expandUint32   [line 703]

string expandUint32( string $_int)

PHP doesn't support unsigned integers, but many of the RR's return unsigned values (like SOA), so there is the possibility that the value will overrun on 32bit systems, and you'll end up with a negative value.

64bit systems are not affected, as their PHP_IN_MAX value should be 64bit (ie 9223372036854775807)

This function returns a negative integer value, as a string, with the correct unsigned value.

  • Return: returns the unsigned value as a string.
  • Access: public

Parameters:

string   $_int   —  the unsigned integer value to check

[ Top ]

isIPv4   [line 721]

boolean isIPv4( string $_address)

returns true/false if the given address is a valid IPv4 address
  • Return: returns true/false if the address is IPv4 address
  • Access: public

Parameters:

string   $_address   —  the IPv4 address to check

[ Top ]

isIPv6   [line 760]

boolean isIPv6( string $_address)

returns true/false if the given address is a valid IPv6 address
  • Return: returns true/false if the address is IPv6 address
  • Access: public

Parameters:

string   $_address   —  the IPv6 address to check

[ Top ]

sendPacket   [line 851]

mixed sendPacket( Net_DNS2_Packet $request, boolean $use_tcp)

sends a standard Net_DNS2_Packet_Request packet
  • Return: returns a Net_DNS2_Packet_Response object, or false on error
  • Throws: Net_DNS2_Exception
  • Access: protected

Parameters:

Net_DNS2_Packet   $request   —  a Net_DNS2_Packet_Request object
boolean   $use_tcp   —  true/false if the function should use TCP for the request

[ Top ]

setServers   [line 366]

boolean setServers( mixed $nameservers)

sets the name servers to be used
  • Throws: Net_DNS2_Exception
  • Access: public

Parameters:

mixed   $nameservers   —  either an array of name servers, or a file name to parse, assuming it's in the resolv.conf format

[ Top ]

[ Top ]

signTSIG   [line 535]

boolean signTSIG( string $keyname, [string $signature = ''], [string $algorithm = Net_DNS2_RR_TSIG::HMAC_MD5])

adds a TSIG RR object for authentication
  • Since: function available since release 1.1.0
