PHP Network Functions
EditRocket provides the following information on Network functions in the PHP source code builder.
int checkdnsrr ( string $host [, string $type ] ) - Searches DNS for records of type type corresponding to host.
bool closelog ( void ) - closelog() closes the descriptor being used to write to the system logger. The use of closelog() is optional.
int debugger_off ( void ) - Disable internal PHP debugger.
int debugger_on ( string $address ) - Enables the internal PHP debugger, connecting it to address.
void define_syslog_variables ( void ) - Initializes all constants used in the syslog functions.
-
-
array dns_get_record ( string $hostname [, int $type [, array &$authns ]], array &$addtl ) - Fetch DNS Resource Records associated with the given hostname.
resource fsockopen ( string $hostname [, int $port [, int &$errno [, string &$errstr [, float $timeout ]]]] ) - Initiates a socket connection to the resource specified by hostname.
string gethostbyaddr ( string $ip_address ) - Returns the host name of the Internet host specified by ip_address.
string gethostbyname ( string $hostname ) - Returns the IP address of the Internet host specified by hostname.
array gethostbynamel ( string $hostname ) - Returns a list of IP addresses to which the Internet host specified by hostname resolves.
bool getmxrr ( string $hostname , array &$mxhosts [, array &$weight ] ) - Searches DNS for MX records corresponding to hostname.
int getprotobyname ( string $name ) - getprotobyname() returns the protocol number associated with the protocol name as per /etc/protocols.
string getprotobynumber ( int $number ) - getprotobynumber() returns the protocol name associated with protocol number as per /etc/protocols.
int getservbyname ( string $service , string $protocol ) - getservbyname() returns the Internet port which corresponds to service for the specified protocol as per /etc/services.
string getservbyport ( int $port , string $protocol ) - getservbyport() returns the Internet service associated with port for the specified protocol as per /etc/services.
void header ( string $string [, bool $replace [, int $http_response_code ]] ) -
array headers_list ( void ) - headers_list() will return a list of headers to be sent to the browser / client.
bool headers_sent ([ string &$file [, int &$line ]] ) - Checks if or where headers have been sent.
string inet_ntop ( string $in_addr ) -
string inet_pton ( string $address ) - This function converts a human readable IPv4 or IPv6 address (if PHP was built with IPv6 support enabled) into an address family appropriate 32bit or 128bit binary structure.
int ip2long ( string $ip_address ) - The function ip2long() generates an IPv4 Internet network address from its Internet standard format (dotted string) representation.
string long2ip ( int $proper_address ) - The function long2ip() generates an Internet address in dotted format (i.e.: aaa.bbb.ccc.ddd) from the proper address representation.
bool openlog ( string $ident , int $option , int $facility ) - openlog() opens a connection to the system logger for a program.
resource pfsockopen ( string $hostname [, int $port [, int &$errno [, string &$errstr [, float $timeout ]]]] ) -
bool setcookie ( string $name [, string $value [, int $expire [, string $path [, string $domain [, bool $secure [, bool $httponly ]]]]]] ) - setcookie() defines a cookie to be sent along with the rest of the HTTP headers. Like other headers, cookies must be sent before any output from your script (this is a protocol restriction). This requires that you place calls to this function prior to any output, including and
tags as well as any whitespace.bool setrawcookie ( string $name [, string $value [, int $expire [, string $path [, string $domain [, bool $secure [, bool $httponly ]]]]]] ) -
-
-
-
bool syslog ( int $priority , string $message ) - syslog() generates a log message that will be distributed by the system logger.
