PHP preg_replace_callback替换preg_replace的问题

Question

$pattern = '/<!--\s#BeginLibraryItem\s\"\/(.*?)\"\s-->.*?<!--\s#EndLibraryItem\s-->/se';

$replacement = "'{include file='.strtolower('\1'). '}'";
$source = preg_replace($pattern, $replacement, $source);

本来是这样的，现在因为PHP版本升级，/e匹配会报错，需要用preg_replace_callback函数替换preg_replace

求大神教教怎么写，试了好久都有问题
