以下new_content是mysql中使用select返回的内容 

$new_content='<P>下面我给大家讲讲javascript函数：</P><PRE class=js name="code"><script> <BR>function show() <BR>{ <BR>alert("hello world"); <BR>} <BR></script>
Copy after login
Copy after login

结果如图：
tu1

';
请问如何将其中的<script>和</script>转换成<script>和</script>


回复讨论(解决方案)

htmlspecialchars这个函数可以转义 

$new_content='<P>下面我给大家讲讲javascript函数：</P><PRE class=js name="code"><script> <BR>function show() <BR>{ <BR>alert("hello world"); <BR>} <BR></script>
Copy after login
Copy after login

结果如图：
tu1

';var_dump(preg_replace_callback('/<\/?script>/i', function($r){return htmlentities($r[0]);}, $new_content)) ;
