How to link a file into another file but in different folders on my server?

sorry if my title didnt make sense but what i want to do is this :

have a folder in my server called "components"
which contains a php file called "header.php"

then in another folder in my server i want a folder called "blog"
which contains a php file called "entry 1" which can include the "header.php" file

ive tried but cant get it to work

 

Just use the absolute path.

let's say your domain name is xxx.tld

the absolute path to "header.php" would be
http://xxx.tld/components/header.php



I hope that helped.

 

thanks mate
