【求助】preg_replace转成preg_replace_callback

[hua_zhixing_]

如何把下面代码中的preg_replace用preg_replace_callback代替？

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

这是ECShop里的代码，安装在php 5.5.x版本上时，会出现这类问题。

preg_replace_callback("/(\\'\$[^,]+)/" , function($r){return stripslashes(trim($r[1],'\''));}, var_export($t, true))

转成:

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

报错：
