What difference does it make if the web page extensions is php3 instead of php ? What are the differences between the two ?
Difference in php and php.3
in php version 3.x the .php3 file extension used to be common (i dont think it was mandatory). on occasion ive seen .php4 and even once .php5 as file extensions before, but i think it can be said that since php v4 the .php file extension is standard.
