How to pass a function to another page?

[stevew]

functions.php

 

<?php
function copyright(){
    echo "July 30, 2012<br />";
}

?>
<?php
{
    echo copyright();
}

Result: July 30, 2012

 

 

 

How would I call this function from say footer.php?

[Jessica]

on that page, require_once('functions.php');

[stevew]

Thank you.

 

How do I require it more than "once"?

ie once in footer.php and once in  header.php?

[Jessica]

Don't require it more than once, because then you'll be defining the function more than once. Just call the function in header and footer.

also you're being redundant, you call echo copyright() but copyright doesn't return anything, it just echos. This is wrong.

Got it thanks. Ya, I noticed it seemed redundant () but was only using as an example. 

Thanks again
