php include
PHP Include is very simple and very easy to understand, but using this you must save all your files as '.php' for them to work. Just follow these easy understanding steps below,
First you want to make a file with all your coding in it. So just follow the same steps as 'making your homepage'. You need to make a file called 'coding.php'.
Once you have that done, paste
all of your website coding in there. But make sure the content section is at the bottom without closing to that section. Such as this,

So that way the content section will turn out just fine. Then you make a new file call it whatever you want, 'yourfilename.php' Then, include this code to that file when in the editing process,
without any spaces; remove the spaces.
Then there it is, for each file(page) you make make sure to include '.php' in the file name and ALWAYS put that code at the top of each file. Saves you time and all the work.
