Net_Portscan::checkPortRange()
Synopsis
array Net_Portscan::checkPortRange ( string $host , integer $minPort , integer $maxPort , integer $timeout = 30 )
This function checks if there are services available at the specified ports on the specified machine.
Parameter
-
string $host - address of the host to check
-
string $minPort - lowest port to test to check
-
string $maxPort - highest port to test to check
-
string $timeout - time in seconds to wait for every 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
array - An associative array containing the scanning results for each port.
Note
This function can be called statically.
Example
Using checkPortRange
<?php
require_once "Net_Portscan/Portscan.php";
echo "Scanning localhost ports 70-90\n";
$result = Net_Portscan::checkPortRange("localhost", 70, 90);
foreach ($result as $port => $element) {
if ($element == NET_PORTSCAN_SERVICE_FOUND) {
echo "A service has been found on port " . $port . ".\n";
} else {
echo "No service has been found on port " . $port . ".\n";
}
}
