How can PHP developers optimize resource usage when implementing a template engine in a large project?

To optimize resource usage when implementing a template engine in a large project, PHP developers can utilize caching mechanisms to store compiled templates and reduce the need for repeated parsing and rendering. By caching compiled templates, developers can improve performance and reduce the load on the server, resulting in faster response times for users. 

// Example of caching compiled templates using PHP
function renderTemplate($templateName, $data) {
    $cacheKey = 'template_' . $templateName;
    $cachedTemplate = apc_fetch($cacheKey);

    if (!$cachedTemplate) {
        $compiledTemplate = compileTemplate($templateName);
        apc_store($cacheKey, $compiledTemplate);
        $cachedTemplate = $compiledTemplate;
    }

    return renderCompiledTemplate($cachedTemplate, $data);
}
