SNAT provides a secure mechanism for translating internal, nonroutable addresses into routable addresses. As traffic flows out of a data center, the gateway and source address of IP packets are translated and switched to the appropriate upstream gateway router. This ensures that traffic is sent and returned through the desired path.
To extend the reach of the IPv4 address space, companies have turned to using private IPv4 addresses through a public-to-private address translation technique known as network address translation (NAT).
In conjunction with a NAT-enabled gateway or router device, a privately addressed network may hide hundreds or thousands of hosts behind a single public address. The NAT device differentiates among the PCs by translating their port numbers into unique values.
But NAT is limited by applications such as streaming media that transmit IP addresses or port numbers in the payloads of packets. Such applications require that NAT take on application-specific knowledge and perform additional computation.
Worse, because NAT typically resides in a boundary router between private and public networks, it can't function with IP Security (IPSec), the popular encryption technology for virtual private networks. IPSec requires true end-to-end handshaking in order to set up initial encryption rules. Once encrypted at a client system, IPSec packets cannot be modified - or recognized - by NAT.
Destination NAT with netfilter is commonly used to publish a service from an internal RFC 1918 network to a publicly accessible IP. To enable DNAT, at least one iptables command is required. The connection tracking mechanism of netfilter will ensure that subsequent packets exchanged in either direction (which can be identified as part of the existing DNAT connection) are also transformed.

array array_slice ( array $array , int $offset [,int $length [, bool $preserve_keys = false ]] )
Extract a slice of the array
Example :$input= array("a", "b", "c", "d", "e");
$output = array_slice($input, 2); // returns "c", "d", and "e"
$output = array_slice($input, -2, 1); // returns "d"
$output = array_slice($input, 0, 3); // returns "a", "b", and "c"
// note the differences in the array keys
print_r(array_slice($input, 2, -1));
print_r(array_slice($input, 2, -1, true));
array array_splice ( array &$input , int $offset [, int $length = 0 [, mixed $replacement ]] )
Remove a portion of the array and replace it with something else
Example := array("red", "green", "blue", "yellow");
array_splice($input, 2);
// $input is now array("red", "green")
$input = array("red", "green", "blue", "yellow");
array_splice($input, 1, -1);
// $input is now array("red", "yellow")
$input = array("red", "green", "blue", "yellow");
array_splice($input, 1, count($input), "orange");
// $input is now array("red", "orange")
$input = array("red", "green", "blue", "yellow");
array_splice($input, -1, 1, array("black", "maroon"));
// $input is now array("red", "green",
// "blue", "black", "maroon")
$input = array("red", "green", "blue", "yellow");
array_splice($input, 3, 0, "purple");
// $input is now array("red", "green",
// "blue", "purple", "yellow");
