Php 保存以数组形式存储的数组内容';s内部阵列
我有这个数组。我只想将此数组([choices])中一个的内容提取到一个新数组中。我如何用php实现它Php 保存以数组形式存储的数组内容';s内部阵列,php,Php,我有这个数组。我只想将此数组([choices])中一个的内容提取到一个新数组中。我如何用php实现它 Array ( [0] => Array ( [key] => field_54df3275b708a [label] => Idioma [name] => idioma [type] => select [ins

我尝试了以下代码(我认为这是一个糟糕的代码):
foreach($k=>v的数组){
if(is_数组($v)){
foreach($v为$l=>$w){
如果($w){
foreach($w为$s=>t){
$idiomas[]=$t.
;
}
}
}
}
}
但它将[choices]和[conditional_logic]保存到新数组中,我只需要[choices]
非常感谢您因为您一直在每个foreach中使用钥匙,您可以使用它来确保它是您想要的阵列:
foreach($array as $k=>$v) {
if (is_array($v)) {
foreach($v as $l=>$w) {
if ($w && $l == 'choices') { // $w is the wanted array
foreach($w as $s=>$t) {
$idiomas[]=$t.'<br />';
}
}
}
}
}
foreach($k=>v的数组){
if(is_数组($v)){
foreach($v为$l=>$w){
如果($w&&$l=='choices'){/$w是需要的数组
foreach($w为$s=>t){
$idiomas[]=$t.
;
}
}
}
}
}
如果
($w)
,我不确定你在测试什么,尽管用你的实际数组替换$arr
,它仍然可以工作
// your array (replace)
$arr = array(
"required" => 0,
"choices" => array(
"Catalan" => "Catalan",
"Castellano" => "Castellano",
"Ingles" => "Ingles",
),
"default" => NULL,
);
// the empty resulting array
$new_arr = array();
foreach($arr["choices"] as $key)
array_push($new_arr, $arr["choices"][$key]);
// your resulting array
print_r($new_arr);
您所需的数组保存在数组中
$new\u arr
$new\u array\u choices=$array[0]['choices'代码>
我花了一段时间创建了一个。我必须手动重新创建数组。第一个数组是否有多个元素,还是要选择每个“子”数组?$new\u array\u choices=$array[0][choices]代码>?@zipzit你是最棒的。简单而奇妙!!!谢谢
// your array (replace)
$arr = array(
"required" => 0,
"choices" => array(
"Catalan" => "Catalan",
"Castellano" => "Castellano",
"Ingles" => "Ingles",
),
"default" => NULL,
);
// the empty resulting array
$new_arr = array();
foreach($arr["choices"] as $key)
array_push($new_arr, $arr["choices"][$key]);
// your resulting array
print_r($new_arr);
