试试，没有环境没办法测试，根据提示信息改的

第483行：改成

$out = "<?php \n" . '$k = ' . preg_replace_callback("/(\'\\$[^,]+)/e" , function($r) { return stripslashes(trim('\\1','\'')); }, var_export($t, true)) . ";\n";

第1061行：改成

//$pattern     = '/<!--\s#BeginLibraryItem\s\"\/(.*?)\"\s-->.*?<!--\s#EndLibraryItem\s-->/se';
//$replacement = "'{include file='.strtolower('\\1'). '}'";
$source      = preg_replace('/<!--\s#BeginLibraryItem\s\"\/(.*?)\"\s-->.*?<!--\s#EndLibraryItem\s-->/se', function($r) { return '{include file='.strtolower('\\1'). '}';}, $source);

提示很清楚了啊
把preg_replace换成preg_replace_callback
看看preg_replace_callback的用法就明白了

/*
1、e参数去掉
2、后面的\1换成回调的数组对应的元素
*/
