怎么取同一php文件里的post值
代码假设为 

<br /><?php<br />if($_POST) {<br />$a = $_POST['a'];<br /> echo "$a ";   //可以正常输出的。<br />}else{<br />$a = $_POST['a'];<br /> echo "$a ";   //不能输出值！！！！！<br />}<br />?><br />
Copy after login



请问下，怎么才能在 else 里面获得 $_POST['a'] 的值？求办法。

说说你具体的需求，才能更好的回答你得问题。你这说的完全不清楚，无法回答。


就是在POST页面填写了一个内容，然后提交后，在非POST页面要获取这个内容


存到session里，数据库里，文件里，等等，再取
