functions help

[Johnnyboy123]

As painfully simple as this may be, I seem to be doing something wrong as always. New to php and decided to start using functions. I'm trying to add functions from an external functions.php file to my other pages and then call the functions where necessary. How should I go about it? I tried something like this:

 

Functions.php:

<?php
function field() {
echo 'text heherh';
}
?>

 

and then when calling it to when needed for example:

include 'includes/functions.php'; // at the top of the page

<?php
// and when trying to call the function on a specific line 
if (!$sname)
	$errorstring = $errorstring . "<b>Surname:" . field() ; //field being the function name
?>

 

I know this is very simple but I have never used functions before.. tried google, didn't help much and I'm pressed for time so decided to ask here. Thanks in advance

Rather than use echo within your function you'd use return
