根据数组值拆分数组
根据数组值拆分数组
提问于 2011-12-01 00:36:54
我有一个充满动态<select>字段选项的数组，我希望根据每个“循环”中的某个值将其拆分成单独的数组。
基本上，我想要两个数组:一个包含与[subfirmdetailtype_id] = 14相关的数据，另一个包含[subfirmdetailtype] = 25。
任何帮助都将不胜感激！

[0] => Array
(
[Subfirmdetailoption] => Array
(
[option] => Open
[subfirmdetailtype_id] => 14
)

[option] => Closed
[subfirmdetailtype_id] => 14

这将按照您想要的方式对数组进行分组：
$new_array = array();
foreach ($your_array as $array) {
$new_array['subfirmdetailtype_id'][
$array['Subfirmdetailoption']['subfirmdetailtype_id']
][] = $array['Subfirmdetailoption'];
}稍后，您可以像这样访问组：
$new_array['subfirmdetailtype_id'][14];
$new_array['subfirmdetailtype_id'][15];或者循环遍历这些分组的数组。

只是遍历它们吗？像这样：
$allvalues = array();
foreach ($_POST['values'] as $key => $value) {
$allvalues[$value['subfirmdetailtype_id']] = $value['option'];

这就是了：
$myarr = Array(
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Open",
"subfirmdetailtype_id" => 14
)
),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Closed",
"subfirmdetailtype_id" => 14
)
),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Large Growth",
"subfirmdetailtype_id" => 25
)
),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Large Blend",
"subfirmdetailtype_id" => 25
)
),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Large Value",
"subfirmdetailtype_id" => 25
)
),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Mid Growth",
"subfirmdetailtype_id" => 25
)
),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Mid Blend",
"subfirmdetailtype_id" => 25
)
),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Small Growth",
"subfirmdetailtype_id" => 25
)
),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Small Blend",
"subfirmdetailtype_id" => 25
)
),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Small Value",
"subfirmdetailtype_id" => 25
)
),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "World Bond",
"subfirmdetailtype_id" => 25
)
),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Multisector Bond",
"subfirmdetailtype_id" => 25

),
Array
(
"Subfirmdetailoption" => Array
(
"option" => "Municipal Debt",
"subfirmdetailtype_id" => 25

),
Array

foreach($myarr as $elem){
if ($elem["Subfirmdetailoption"]["subfirmdetailtype_id"] == 14) {
$id14[] = $elem["Subfirmdetailoption"]["option"];
}
if ($elem["Subfirmdetailoption"]["subfirmdetailtype_id"] == 25) {
$id25[] = $elem["Subfirmdetailoption"]["option"];
}
}
print_r($id14);
print_r($id25);
