这是将javascript数组转换为php数组的代码.....这是用cookies完成的...
function getCookie(c_name)
{
var i,x,y,ARRcookies=document.cookie.split(";");
for (i=0;i<ARRcookies.length;i++)
{
x=ARRcookies[i].substr(0,ARRcookies[i].indexOf("="));
y=ARRcookies[i].substr(ARRcookies[i].indexOf("=")+1);
x=x.replace(/^\s+|\s+$/g,"");
if (x==c_name)
{
return unescape(y);
}
}
}
function setCookie(c_name,value,exdays)
{
var exdate=new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value=escape(value) + ((exdays==null) ? "" : "; expires="+exdate.toUTCString());
document.cookie=c_name + "=" + c_value;
}
function checkCookie()
{
var a_php = "";
var a=new Array();
/*
a[0]="Saab";
a[1]="Volvo";
a[2]="BMW";
a[3]="sample"
a[4]="Saab";
a[5]="Volvo";
a[6]="BMW";
a[7]="sample"
a[8]="Saab";
a[9]="Volvo";
a[10]="BMW";
a[11]="sample"
a[12]="Saab";
a[13]="Volvo";
a[14]="BMW";
a[15]="sample"
a[16]="Saab";
a[17]="Volvo";
a[18]="BMW";
a[19]="sample"
a[20]="Saab";
a[21]="Volvo";
a[22]="BMW";
a[23]="sample"
a[24]="Saab";
a[25]="Volvo";
a[26]="BMW";
a[27]="sample"
*/
for(var t=0;t<350;t++)
a[t]="hello"+t;
for(var count=0;count<a.length;count++)
a_php = a_php+a[count]+",";
setCookie("new_cookie1",a_php,3);
}
</script>
is there any possible way to convert javascript array to php without cookies....

Sometimes it is not possible to change server side to change output to json. I had input in the form i.e.
[ ['azz2465014416', '8', '22'],['azz2465014418', '10', '22'],['azz2465014420', '12', '22'],['azz2465014422', '14', '22'] ]
有时无法更改服务器端以将输出更改为 json。我输入了表格即
[ ['azz2465014416', '8', '22'],['azz2465014418', '10', '22'],['azz2465014420', '12', '22'],['azz2465014422', '14', '22'] ]
and I get php array from this input using this php code:
我使用这个 php 代码从这个输入中获取 php 数组：
<?php
$a = "[ ['azz2465014416', '8', '22'],['azz2465014418', '10', '22'],['azz2465014420', '12', '22'],['azz2465014422', '14', '22'] ]";
$b = '$c = '.(str_replace(array('[',']'),array('array(',')'),$a)).';';
eval($b);
print_r($c);
you will have then in varible $c resulted output. This is not ideal solution. It will not cover every javascript array, but if you have trouble with some array, you can change it to cover your situation.
然后您将在变量 $c 中获得结果输出。这不是理想的解决方案。它不会涵盖每个 javascript 数组，但如果您对某些数组有问题，您可以更改它以涵盖您的情况。

In JS:
在JS中：
var a, s;
a = [ 'one', 'two', 'three'];
s = JSON.stringify( a );
//Do something to send `s` to the server in a request
In PHP, assuming scame from client in a cookie
在 PHP 中，假设s来自客户端的 cookie
<?php
$a = json_decode( $_COOKIE['s'], true );
Simple as that.
就那么简单。

You Should Post it to another(or current) page to be processed with PHP. If you don't want page to be redirected Use AJAX to send Array to PHP.
您应该将其发布到另一个（或当前）页面以使用 PHP 进行处理。如果您不想重定向页面，请使用 AJAX 将 Array 发送到 PHP。

You can use JSON to do this.
On the JavaScript-side, just use JSON.stringify(theArray);to create a JSON-representation of that array.
In PHP you can use json_decode(theString, true);to get the array
Links:
http://php.net/manual/function.json-decode.phphttp://en.wikipedia.org/wiki/JSON
您可以使用 JSON 来执行此操作。在 JavaScript 端，只需用于JSON.stringify(theArray);创建该数组的 JSON 表示。在 PHP 中，您可以使用json_decode(theString, true);获取数组链接：http:
