php怎样通过匹配表单名的部分字符串来获取相应表单的值

求助：php怎样通过匹配表单名的部分字符串来获取相应表单的值？
问题可能听着有点绕。
就是我的表单页面个表单个数是不定的，因为有增加表单的按钮，用户可以通过按这个按钮来增加表单个数，而表单的名字我是把它做了一个 ”前缀+递增数字“ 的形式， 比如 ”array_1“, "array_2"， 但是具体多少个是不定的，因为要看用户增加了多少个表单，所以，我现在要把所有的带 array_ 前缀的所有表单的值，放到一个数组里面，怎么实现呢？ 关键问题是不表单的个数是未定的。

新手学习，不知道把问题描述清楚了没，先谢过了

是增加表单 还是增加表单元素

你一个页面内有N个表单?

如果确实是有多个表单,我目前是用jquery动态地获取所有的表单值,然后将其传入后台

<br />
var postData="";<br />
$.each($("from"),function(i, n){<br />
    postData += $(n).serialize();<br />
});<br />
//通过ajax传到后台.<br />

不存在多个表单，只存在多个表单变量

foreach(preg_grep('/array_/', array_keys($_POST)) as $k) {<br />
  res[$k] = $_POST[$k];<br />
}<br />

$res 就是你需要的结果

其实你不是命名为 array_数字，而是命名为 array[] 就不需要那么麻烦了
------解决方案--------------------
将同一组元素的name定义成数组即可，如下：


.........

php 接收就是
print_r($_POST['array']);
------解决方案--------------------



print_r($_POST['array']['a1']);
print_r($_POST['array']['a2']);

这样才可以区分input值
