我有一个创建$_POST变量的表单，如：
Array
(
[submit] => Update the List!
[12052,s] => 1
[12052,d] => 0
[12052,r] => 1
[11271,s] => 1
[11271,d] => 0
[11271,r] => 5
[16008,s] => 0
[16008,d] => 0
[16008,r] => 4
)
我想用PHP把它转换成一个多维数组，比如：
Array
(
[12052] => Array
(
[s] => 1
[d] => 0
[r] => 1
)
[11271] => Array
(
[s] => 1
[d] => 0
[r] => 5
)
[16008] => Array
(
[s] => 0
[d] => 0
[r] => 4
)
)
我知道我可以用以下代码手动制作这样的数组：
$test = array("12052" => array("s"=>"1","d"=>"0","r"=>"1"),"11271" => array("s"=>"1","d"=>"0","r"=>"5"),"16008" => array("s"=>"0","d"=>"0","r"=>"4"));
谢谢你帮我找出最好的方法！
试试这个：
$result = array();
foreach ($_POST as $key => $value) {
if ($key !== 'submit') {
$key = strtok($key, ','); // remove everything after ','
$result[$key][] = $value;
}
}
演示
以下代码应该可以工作：
$arr = array();
foreach(array_diff_key($_POST, array("submit" => "")) as $key => $val){
$exp = explode(",", $key, 2);
$arr[$exp[0]][$exp[1]] = $val;
}
print_r($arr); // Outputs the multidimensional array
