php提交post数组参数实例分析_php技巧
本文实例分析了php提交post数组参数的用法。分享给大家供大家参考,具体如下:
首先php中要想从页面传送数组到服务端a,要在页面上多个空间同名,而且对于名称有要求,那就是 name="aa[ ]",注意这里要多加一个数组的符号,这样才能在服务端a取到
得到的为数组。
更深一层的问题是,假设我现在需要对post中的参数进行处理后,再传送给另外一个服务端,对于参数aa,应该怎么传递呢?
如果不做什么处理,拼装完post请求后,服务端b获取到的永远只是Array,无法取到实际值。
现在的解决方案是:现在服务端a进行序列化,然后在服务端b接收后进行反序列化。这样反序列化后的值就是一个数组了,和a段获取到的一样。
序列化
反序列化
$a = "a:2:{i:0;s:1:\"1\";i:1;s:1:\"2\";}"; var_dump(unserialize($a));
结果是什么呢:
array(2) { [0]=> string(1) "1" [1]=> string(1) "2" }
而在post中获取到的序列化后的参数是有进行添加过转义符的,获取后需要去掉,然后才能反序列化成功
$bb = $_POST["aa"]; $bb = str_replace("\\", '', $bb); var_dump(unserialize($a));
好了,这样才是你要的结果。
当然,还有一种问题是,你可以直接把数组值传递给页面的某一空间,提交给服务端。这种情况同样需要序列化和反序列化。
页面
<input type="hidden" name="aa" value="<?php echo base64_encode(serialize($array));?>" /> var_dump(base64_decode(unserialize(<pre class="html" name="code">{1}
POST['post_data'])));
不知道加了这个base64_encode有什么作用,貌似是给中文编码的吧?
希望本文所述对大家php程序设计有所帮助。
