PHP:如何修改动态多维阵列

Question

我具有一个函数，用户可以动态创建树视图层次结构。因此，每次用户创建一个新的treeview，我都会得到一组不同的数组，例如这样。因此，在用户完成TreeView之后，请单击"提交"，我只是直接将对象属性从JS传递到PHP，我无法更改JS的数据，因为其插件Vue-Jstree，因此我打算在PHP中更改它。但是，它不是修复的数组集，我可以告诉它它是否只有2 forloop。什么逻辑要删除或编辑所有这些键，甚至它的深度

Array
(
    [0] => Array
        (
            [id] => 0
            [text] => Hi-flyer
            [value] => Hi-flyer
            [icon] => fa fa-user
            [opened] => 1
            [selected] => 1
            [disabled] => 
            [loading] => 
            [children] => Array
                (
                    [0] => Array
                        (
                            [id] => 1
                            [text] => Cynthia Abanes
                            [value] => 5710

                            [loading] => 
                            [children] => Array
                                (
                                )
                        )
                    [1] => Array
                        (
                            [id] => 2
                            [text] => Ronnie De Guzman
                            [value] => 5806

                                (

Answer 1

您可以使用递归函数像下面一样执行此操作，

$array = array("id" => "value1", "value" => "Test", "text" => "Test", "loading" => "100", "children" => array("id" => "value1","value" => "Test","text" => "Test","loading" => "100","children" => array("id" => "value1", "value" => "Test",)));
$keys = ["text", "loading"]; //add all keys which are you want to remove
//we loop all keys and run arrayRemove function over each key here
foreach($keys as $key){
  arrayRemove($array, $key);
}
function arrayRemove(&$array, $key) {
   unset($array[$key]);
   foreach ($array as &$value) {
      if (is_array($value)) {
         arrayRemove($value, $key);
      }
   }
}

我的数组与您的数组不同，无论如何这将完成您的工作:)，结果将如下所示，

Array ( [id] => value1 [value] => Test [children] => Array ( [id] => value1 [value] => Test [children] => Array ( [id] => value1 [value] => Test ) ) )

Answer 2

您可以使用此

<?php 
    for ($i=0; $i < count($yourArray); $i++) { 
        unset($yourArray[$i]['text']);
        unset($yourArray[$i]['icon']);
        unset($yourArray[$i]['opened']);
    }
    // then display to check
    var_dump($yourArray);
?>

Answer 3

我看到了您的代码，并尝试解决您的问题。这是非常简单的递归过程，可以帮助解决您的问题。只需查看我的代码并尝试找到您的欲望。

<?php
$data = array(
        array('id'=>1,'text'=>'hi-flyer','icon'=>'fa fa-user','opened'=>1,'selected'=>1,'disabled','loading','children'=>array()),
        array('id'=>2,'text'=>'hi-flyer','icon'=>'fa fa-user','opened'=>1,'selected'=>1,'disabled','loading','children'=>array(array('id'=>4,'text'=>'hi-flyer','icon'=>'fa fa-user','opened'=>1,'selected'=>1,'disabled','loading','children'=>array()),array('id'=>5,'text'=>'hi-flyer','icon'=>'fa fa-user','opened'=>1,'selected'=>1,'disabled','loading','children'=>array()))),
        array('id'=>3,'text'=>'hi-flyer','icon'=>'fa fa-user','opened'=>1,'selected'=>1,'disabled','loading','children'=>array())
);
$data = change_text_using_id(1,$data,"Hello world!");
print_all_id_text($data);

function change_text_using_id($id,$data,$text){
    for($i=0;$i<count($data);$i++){
        if($id == $data[$i]['id']){
            $data[$i]['text'] = $text;
            echo "success<br>";
        }else if(count($data[$i]['children'])>0){
            $data[$i]['children'] = change_text_using_id($id,$data[$i]['children'],$text);
        }
    }
    return $data;
}
function print_all_id_text($data){
    for($i=0;$i<count($data);$i++){
        echo "ID==> ".$data[$i]['id']." And Text==> ".$data[$i]['text'].'<br>';
        if(count($data[$i]['children'])>0){
            print_all_id_text($data[$i]['children']);
        }
    }
}

谢谢。我认为您找到了答案。快乐编码：D
