Question

does anyone know a php templating system that is very simple, something like almost as simple as str_replace("{variable}", $variable); ?

I need this for a series of textareas in the administration panel, where the site admin should change templates for various elements of the website (not complex stuff like pages etc, just blocks of content)

Answer 1

/**
 * Renders a single line. Looks for {{ var }}
 *
 * @param string $string
 * @param array $parameters
 *
 * @return string
 */
function renderString($string, array $parameters)
{
    $replacer = function ($match) use ($parameters)
    {
        return isset($parameters[$match[1]]) ? $parameters[$match[1]] : $match[0];
    };

    return preg_replace_callback('/{{\s*(.+?)\s*}}/', $replacer, $string);
}
