Getting an IPv4 address with PHP is a relatively easy process. It can be done using the gethostname() function, which returns the host name of the current machine. Additionally, it can also be achieved using functions such as gethostbyaddr(), inet_pton(), and ip2long(). The first two will return a human readable IP address, while ip2long() will convert it into integer representation of that same IP address. This makes finding any specific IPv4 addresses within your network much simpler and more efficient. Furthermore, these same techniques can also work for obtaining other types of addresses including IPv6 or MAC Addresses as well – though slightly different methods may need to be employed depending on what type of information you are trying to obtain. All in all, getting an IPv4 address with PHP is quite straightforward and provides many useful functionality options for developers looking to interact with their networks programmatically.
