lithium\net\HostString::parse()

public static method

Parses host string that can either hold just the host name (i.e. localhost), a host/port combination (i.e. localhost:8080) or just the port prefixed with a colon (i.e. :8080). Also works with IPv4 and IPv6 addresses.

Note: IPv6 addresses must be enclosed in square brackets '[::1]:80'.

Parameters

string $host
The host string with host, host/port or just port.

Returns

array

An associative array containing parsed 'host', 'port' or both.
