如何分配我尝试过的关联数组选项

    $arr=$this->input->post('option[]');

    foreach($arr as $key => $value) 
    {
        echo($key);
    }

Answer 1

试试这个

$arr=$this->input->post('option');

Answer 2

试试这个

<?php
$arr = $_POST["option"];

foreach($arr as $key => $value){
   echo $key.":".$value;
}
?>

Answer 3

$ this-＆gt; input-post（'field_name'）在$ _POST数组中查找名为'field_name'的键。试试这个。

$arr=$this->input->post('option[adress]');

foreach($arr as $key => $value) 
{
    echo($key);
}
