PHP。走到多维数组?
我有一个包含数组和对象多维arrray。我在它来搜索一个值。我该怎么办?
I have a multidimensional arrray which contains arrays and objects. I have to search one value in it. How can I do?
view Object
(
[db_table] => views_view
[base_table] => users
[args] => Array
(
)
[use_ajax] =>
[result] => Array
(
)
[pager] => Array
(
[use_pager] =>
[items_per_page] => 10
[element] => 0
[offset] => 0
[current_page] => 0
)
[old_view] => Array
(
[0] =>
)
[vid] => 1
[name] => userone
[description] => userone
[tag] =>
[view_php] =>
[is_cacheable] => 0
[display] => Array
(
[default] => views_display Object
(
[db_table] => views_display
[vid] => 1
[id] => default
[display_title] => Defaults
[display_plugin] => default
[position] => 1
[display_options] => Array
(
这一样的阵列继续。我怎样才能如果值存在搜索?
Like this the array continue. How can I search if one value exists?
推荐答案
如果你只是想看看某个值存在,没有别的,这是微不足道的使用的递归迭代的:
If you only want to find out if a certain value exists and nothing else, this is trivial using recursive iterators:
$found = false;
foreach (new RecursiveIteratorIterator(new RecursiveArrayIterator($array)) as $value) {
if ($value == 'theValueImLookingFor') {
$found = true;
break;
}
}
这不是更复杂的递归函数写这个了:
It's not much more complex to write this up in a recursive function:
function recursive_in_array($array, $needle) {
foreach ($array as $value) {
$isIterable = is_object($value) || is_array($value);
if ($value == $needle || ($isIterable && recursive_in_array($value, $needle))) {
return true;
}
}
return false;
}
