echo '';
所以想通过写文件，读文件的方式来解决
if(empty($_REQUEST)){
<code>$html = </code> Copy after login
Copy after login
提交<script></script>
<code>$("#button").click(
function(){
$("#eval").load('',{content:$("#content").val()});
}
);
//ctrl +回车
function ctlSubmit(event) {
if (event.ctrlKey && event.keyCode == 13) { $("#button").click() }
}</code> Copy after login
Copy after login
<code>$content = $_REQUEST['content'];
$content = preg_replace('/；/',';',$content);// 分号容易犯错
$string = addslashes($content);
// echo $string;
// echo '<br>';
if(eval($string) === false){
echo '输入错误';
}</code> Copy after login
Copy after login
}
echo ''; 返回空 不是被PHP解析了 是被当成 HTML 标记了，你查看网页源代码看看……
你要输出带有 等特殊符号的内容到网页上，要用 htmlspecialchars 函数进行处理的呀 …… 不是 addslashes ， addslashes 是用来处理 SQL 过滤的……
