This small function replaces tokens in a string with values passed in as an associative array. Useful for creating small templates when something like Smarty is overkill or not available

Works great for quick form to email scripts.

<?php
function replaceTokens($tokenArr, $template)
{
    while(list($token, $value) = each($tokenArr))
    {
        $template = str_replace("<%".$token."%>", $value, $template);
    }

    return $template;
}


Example:
$tokenArray = array();
$tokenArray['name'] = 'My Name';
$tokenArray['email'] = 'foo@bar.com';
$tokenArray['phone'] = '555-1212';

$template = <<<END
Name: <%name%>
Email: <%email%>
Phone: <%phone%>

END;

$parsed = replaceTokens($tokenArray, $template);

print $parsed;
