Today I am going to tell how to validate IPv4 / IP address using PHP. Simple function which will used to check client IP address is valid or not.

Steps to validate IPv4 Address in PHP
  • Split IP address into segments  by dot(.)  using explode function
  • Make sure that there are 4 segments (eg : 192.168.1.45)
  • Make sure that IP cannot start with 0
  • IP segments must be digits & cannot be longer than 3 digits or greater than 255
