以前项目里有个函数:
<code>preg_replace("/([A-Z])/e", "'_' . strtolower('\\1')", $str)
</code>
升级完php之后，就一直报：
<code>preg_replace(): The /e modifier is deprecated, use preg_replace_callback </code>
请问这个要怎么改？

<code class="lang-php">preg_replace_callback('/([A-Z])/',
function ($matches) {
return '_' . strtolower($matches[0]);
},
$str)
</code>
提问前就没有想过看看文档吗？
