Really basic PHP templating

template.php

function template($string, $replace){
    $keys = array_map(function($k) {
        return '{'.$k.'}';
    }, array_keys($replace));
    $vals = array_values($replace);
    return str_replace($keys, $vals, $string);
}


echo tempate("Hello {name}, today is {weather}!", array(
    'name' => 'Dave',
    'weather' => 'sunny',
));
