Net_Portscan::checkPort()
Synopsis
boolean Net_Portscan::checkPort ( string $host , integer $port , integer $timeout = 30 )
This function checks if there is a service available at the specified port on the specified machine.
Parameter
-
string $host - address of the host to check
-
string $port - port to check
-
string $timeout - time in seconds to wait for response from host
If you run into timeout problems despite setting this parameter to a reasonably high value, you need to make sure that the configuration directive default_socket_timeout in the php.ini configuration file does not force the maximum timeout down to a lower value.
Return value
boolean - Returns TRUE on success, FALSE on failure.
Note
This function can be called statically.
Example
Using checkPort
<?php
require_once "Net_Portscan/Portscan.php";
if (Net_Portscan::checkPort("localhost", 80) == NET_PORTSCAN_SERVICE_FOUND) {
echo "There is a service on localhost on port 80 (" . Net_Portscan::getService(80) . ").\n";
}
