Q: Pass variable to string in include file - PHP What I am trying to do is to have an include file with generalized language in a string that will be used across multiple pages, but I also need to pass a variable to the string from the current page.
Here is an example:
Here is a snippet of the index.php page:
<?PHP
require_once($_SERVER['DOCUMENT_ROOT'].'/lib/prefix.php');

echo $GENERAL_STRINGS['user_not_found'];
?>

Here is the include page:
<?PHP
$GENERAL_STRINGS['user_not_found'] = 'User account not found<br /><a href="/register/?email='.$email.'">Register Today for FREE</a>';
?>

The $email variable is always empty when the link is referenced, I assume this is because it is looking for the $email variable from the include page instead of the index page.  Is there a way around this?

A: Use printf() or sprintf():
<?php
$GENERAL_STRINGS['user_not_found'] = 'User account not found<br /><a href="/register/?email=%s">Register Today for FREE</a>';
?>

Use it in this way:
<?php
printf($GENERAL_STRINGS['user_not_found'], urlencode($email));
?>


A: I have tested it. All good. May be, you forgot assigning of $email.
<?PHP
$email = 'emal@email.com';
$GENERAL_STRINGS['user_not_found'] = 'User account not found<br /><a href="/register/?email='.$email.'">Register Today for FREE</a>';
?>
