- I want to define a variable locally (on every page of a site)
- Then create a HTML template with meta tags that use those variables
- Then include it in every page, and fill it with the local variables.
- Theoretical Example:
about.php:
```
<?php
$title = "his is About page"
include "links.php"
?>
<html>
<head>
<?php meta_links(); ?>
```
links.php:
```
function meta_links()
{
    echo "<title><?php $title; ?></title>"
```
But when I try this, I get an error for the $title variable in links.php not being defined (which makes sense, I guess).

How is this done?

You need to pass a parameter. Google “PHP function parameter” for more info, but in brief;

about.php
```
<?php
$title = "This is About page";
include("links.php");
?>
<html>
<head>
<?php echo meta_links($title); ?>
```
links.php
```
<?php
function meta_links($my_title) {
    return $my_title;
}
?>
```

@beverleyh thank you. Makes sense. I’ll try that when I get home.
