How do I call a function which is set in another page?

[c-o-d-e]

If I have a file - functions.php with "function checkit()"

Within index.php page I include functions.php

 

How would I call the fuction in index.php?

Surely just saying "function checkit()" in the middle of no where is going to look a bit odd?

if you included function.php you just call the function, I don't exactly understand what you mean by odd

 

checkit();

Yes it is just that simple. When you "include" a php file in another it is almost exactly the same as if the code from the included file was written in-line to where it was included.

Hmm ok. Odd = empty, it doesn't look like its right, or fits in. Though if it's correct, I wont complain.

In a function, you'd have.. return true, return false.

What would that look like in index.php for function checkit() ?

do you know how to use functions? You use them the exact same way here...including a script in another script is pretty much for all intents and purposes the same as just cut-pasting the stuff in the main script.  Example:

 

functions.php

function makeBold($string) {
   return "<b>" . $string . "</b>";
}

 

index.php

include ('functions.php');

echo makeBold('hello');
// or
$string = makeBold('hello');
echo $string;
